The Clark Street Tunnel is a rail tunnel of the New York City Subway under the East River between the boroughs of Manhattan and Brooklyn, connecting the IRT Broadway–Seventh Avenue Line and IRT Eastern Parkway Line. The 2 train uses the tunnel at all times, while the 3 train uses it all times except late nights.

The tunnel was constructed as part of the Dual Contracts expansion of the subway system, and opened in 1919. After being heavily damaged by flooding caused by Hurricane Sandy in 2012, it was closed on weekends in 2017–2018 to be reconstructed.

Description

edit

The tunnel is about 5,900 feet (1,800 m) long, with about 3,100 feet (940 m) underwater.[1]

History

edit

Planning

edit
 
Emergency exit, Furman Street, Brooklyn

The Interborough Rapid Transit Company (IRT) opened its first subway line in 1904;[2] the line was extended from Manhattan to Downtown Brooklyn in 1908 with the opening of the Joralemon Street Tunnel.[3] Residents of Brooklyn Heights, a largely residential neighborhood near Downtown Brooklyn, expressed concerns in 1909 that there was no subway station within Brooklyn Heights, even though the line had an emergency exit at Joralemon and Hicks Streets in the center of the neighborhood.[4]


"On May 26 , 1908 , the IRT requested the Manhattan Bridge route to connect the Manhattan 3rd Avenue el to the Contract II subway at Nevins Street . Both were refused "[5][6]


1912 decided on[7]; agreement[8]

Cost savings[11] After the first line opened, the city began planning new lines. In April 1912, the New York Public Service Commission gave the Brooklyn Rapid Transit Company (BRT) the right to operate the proposed Clark Street Tunnel under the East River, between Old Slip in Lower Manhattan and Clark Street in Downtown Brooklyn, with a stop along Clark Street.[12][13] The next month, the Old Slip–Clark Street route was assigned to the IRT instead; the plans called for a station at Clark Street.[14][15] As part of the Dual Contracts between the government of New York City, the BRT, and the IRT, which were signed in 1913, the Clark Street Tunnel was assigned to the IRT, becoming the Brooklyn branch of the Broadway–Seventh Avenue Line, which diverged from the original subway south of Times Square.[16]

The Clark Street Tunnel consisted of a pair of 5,900-foot-long (1,800 m) tubes, with a station at the eastern end of the tubes.[17] This station, the line's first stop in Brooklyn, was to be at Clark and Henry Streets[18] and was initially known as the Brooklyn Heights station.[19][20] As early as November 1913, the Public Service Commission had determined that the Brooklyn Heights station would be a deep-level station that would be solely or primarily accessed by elevators.[21] Booth & Flinn Ltd. and the O'Rourke Engineering Construction Company received a $6.47 million contract in July 1914 to build a tunnel between Old Slip in Manhattan and Clark Street in Brooklyn.[22][23]

Construction

edit

Construction of the tunnel began on October 12, 1914, using a tunneling shield in conjunction with compressed air.[24] The tunnel was designed by civil engineer Clifford Milburn Holland, who later served as the first chief engineer of the Holland Tunnel.[25][26] Five hundred men, working in several shifts, excavated the tubes for 24 hours a day.[27]

The north tube was holed through on November 28, 1916,[30][31] followed by the south tube on December 19 of the same year.[32][33]

Need to finish tunnel[52]

By January 1919, the tracks had been completed, but signals and station finishes were still being installed.[53] Because the station was 80 feet (24 m) deep, it could only be accessed by elevators from the lobby of the Hotel St. George.[19] The IRT decided to push forward the tunnel's opening after learning that BRT workers might go on strike.[54]

Operation

edit

On April 15, 1919, the Clark Street Tunnel opened, and this station opened with it, extending West Side Line express trains from Wall Street on the other side of the East River to Atlantic Avenue via a new connection at Borough Hall.[59][60][61] The connection doubled the number of IRT trains that could travel between Manhattan and Brooklyn, and it eased congestion in the Joralemon Street Tunnel,[62] the only other tunnel carrying IRT trains between the two boroughs.[63] Direct express service to Times Square was provided to the inhabitants of Brooklyn for the first time as a result (trains through the Joralemon Street Tunnel made express stops in Manhattan, skipping Times Square).[60] Soon after the station opened, the Public Service Commission began planning to install an escalator there, as passengers had to climb 71 steps to exit the station.[64]

"The problem facing the TA is it doesn't have enough capital funds to both complete that new $ 633 million 63rd Street tunnel and plug the holes in the old Clark Street tube"[79]

1985-POOR condition fans[80]

On December 28, 1990, snowfall on a third rail caused an electrical fire in a tunnel near the Clark Street station, trapping passengers on a subway train for over half an hour. The fire killed two people and injured 149 others;[81] it was the subway's worst-ever fire at the time.[82] Some riders left their train and tried to walk through the smoke-filled tunnel.[83]

The severity of the fire was exacerbated by the fact that ventilation fans near the station were not working.[84][85] The MTA had ordered four replacement fans in 1977[86] but did not install them until after the fire.[87] The fans were modified when MTA officials discovered that the fans would not turn on because they required too much electricity.[87]

Toxic fumes[88]

New fire safety plans[89]

Mix-up[91]

Sandy damage[92]

Hurricane Sandy also damaged the Clark Street Tubes, necessitating a full closure on weekends from June 27, 2017 to June 24, 2018, thus affecting 2, 3, 4, and 5 service. In addition, as a result of the closure for repairs of the Clark Street Tubes, the stations on the Brooklyn Branch of the line (Park Place to Borough Hall, as well as Hoyt Street on the Eastern Parkway Line) saw closures on weekends as well (2 trains continued to operate to Brooklyn on weekdays and weekday late nights as did 3 trains on weekdays except late nights).[93] The new South Ferry station reopened on June 27, 2017, in time to accommodate the Clark Street closures.[94][95][96] Throughout the duration of the Clark Street tunnel closures, a free out-of-system MetroCard transfer was provided between South Ferry (where 2 trains were rerouted from 11:45pm Fridays to 5:00am Mondays), and Bowling Green (where 4 and 5 trains ran local in Brooklyn in place of the 2 and 3 trains during those same times).[97] Normal service on the Brooklyn Branch resumed on June 25, 2018.[98]

BMT changes

edit

On January 22, 1934, the BMT began operating two special morning rush hour express trains from 95th Street to Broad Street via the Manhattan Bridge on an experimental basis. Trains would leave 95th Street and 8:06 a.m. and 8:18 a.m.. Ridership checks found that riders from Bay Ridge heading to downtown Manhattan transferring to expresses at 59th Street and back to tunnel trains at Pacific Street slowed down service through those points. The new trains were expected to speed up Sea Beach and West End service.[1][2][3] In the first week of service, the trains were heavily used. On January 24, BMT officials said that there were no plans at the time for a return express service in the evening.[4]

On December 17, 1934, the BMT began operating two special morning express trains during rush hours from Brighton Beach to Broad Street via the Manhattan Bridge on an experimental basis. Trains would leave Brighton Beach at 8:07 a.m. and 8:19 a.m.,[5] run express via the Brighton Line, and skip DeKalb Avenue and Myrtle Avenue.[6] These trains would be similar to the special service on the Fourth Avenue Line, which was effective at diverting downtown Manhattan-bound passengers from Sea Beach Line express trains to Times Square. Ridership checks had found that many riders along the Brighton Line headed to downtown Manhattan used Brighton express trains to Times Square and transferred at DeKalb Avenue. The heavy interchange at that location slowed up operations of trains in the area and led to congestion on the express trains. There was no additional track capacity for additional express service to Times Square via the Manhattan Bridge. The two special Brighton Line trains during the peak hour were believed to eliminate the need for riders to transfer at DeKalb Avenue and reduce travel times for riders.[7]

On June 14, 1937, another Wall Street Special weekday rush hour express train was added between 95th Street and Broad Street to improve convenience for workers in offices in downtown Manhattan. The trip, leaving 95th Street at 8:30 a.m., supplemented two other express trains, running express via Fourth Avenue and via the Manhattan Bridge.[8] The three trips would leave 95th Street at 8:06 a.m., 8:18 a.m., and 8:30 a.m..The previous trips had been added on January 22, 1934.[9]

Effective June 30, 1950, a series of service improvements was made in Brooklyn service. Two new Brighton expresses to Brighton Beach began operating from Chambers Street via the Montague Street Tunnel weekdays, leaving at 5:05 p.m. and 5:22 p.m..Two new Fourth Avenue expresses to 95th Street began operating via the Manhattan Bridge from that stop at 5:09 p.m. and 5:26 p.m.. West End trains began running express between 36th Street and Pacific Street all times. Sea Beach trains would run express from 59th Street to 36th Street and Pacific Street at all times except for Coney Island-bound trains between 3 a.m. and 7 a.m., which would run local between 36th Street and 59th Street. Saturday morning rush hour Sea Beach trains that skipped 36th Street would now stop there. On Saturdays, West End tunnel trains between Chambers Street and Bay Parkway via Fourth Avenue Local would be replaced with Culver Line tunnel trains between Chambers Street and Stillwell Avenue. Culver Line trains had previously terminated at Ninth Avenue.[10][11]

With the opening of the Harlem River Tunnel and connection to the IRT White Plains Road Line, then known as the West Farms Branch, half of Lenox Avenue Line (East Side Branch) trains were extended to 180th Street—Bronx Park. On the same day, the subway was extended south from Wall Street to Bowling Green and South Ferry loop. All express trains and some Broadway Local trains were extended to South Ferry.[16][15] Trains on the West Farms Branch ran every 30 minutes during late nights, between 12:01 and 6 a.m, and ran every 5 minutes afterwards.[17] Express service continued to end shortly after midnight.

On September 3, 1905, the IRT shortened many of the Sunday Lenox Avenue expresses to 3 cars, having already done so for local trains. The IRT had determined that ridership on Sunday in hot weather was not as popular, with more people traveling by elevated or surface cars, where there was more fresh air.[19]

The Brooklyn extension opened to Atlantic Avenue on May 1, 1908. Dyckman Street expresses, which were half of the Broadway expresses, were extended to Atlantic Avenue during rush hours to accommodate the increased demand from the extension.[25]

All Lenox Avenue express (which included West Farms Express trains) trains would run to Atlantic Avenue between 6:35 a.m. and 1:10 a.m.. All Dyckman Street express trains would also run to Atlantic Avenue between 7:58 and 9:14 a.m. and between 4:56 and 6:37 p.m..

A new schedule took effect on March 14, 1910, adding 128 local and express trains to the schedule, increasing the number of trains run from 1,776 to 1,904. Express trains would run every 1 minute and 48 seconds from 7 to 10 a.m. and from 3:40 to 6:40 p.m., every 2 minutes between 10 and 10:30 a.m., 2:56 to 3:40 p.m., 6:10 to 6:40 p.m., every 2.5 minutes from 10:30 a.m. to 2:53 p.m., and every 3 minutes between 6:40 p.m. and 12:00 a.m.. Between 10:30 a.m. and 2:56 p.m., five- or six-car trains would run on the Broadway branch while eight-car trains would run on the Lenox Avenue branch. Prior to the opening of the subway, engineers estimated that its capacity was 450,000 people a day. Ridership several days a week exceeded 800,000, and on some days exceeded 1 million. This schedule improvement was made possible with the arrival of new train cars.[34][35]

Failure of it and the Dual Contracts

edit

After the statutory debt ceiling for the now-united city of New York had been raised, there were more plans for subway construction until 1908. The Triborough plan comprised three new lines:

The BRT lines were built to wider profiles because the BRT did not want to use IRT trackage, which was narrower by comparison and carried far fewer passengers per hour. The design was inspired by the cars built for the Cambridge subway (MBTA Red Line) which were designed after studies were conducted on the design and operation of a subway car that could carry the most passengers the most efficiently. The rolling stock, however, had to be the same track gauge so the trains could interoperate under the Dual Contracts. The Fourth Avenue and Sea Beach lines were opened on June 19, 1915, after years of delays for building of these lines and the Nassau Street Line. The first BRT section, however, had opened on September 16, 1908, from Essex Street across the Williamsburg Bridge, but using narrow-width cars.[40]

 
1910 plan for IRT expansion

The Triborough System was a proclamation for new subway lines to the Bronx and Brooklyn. The new lines include the IRT Lexington Avenue Line, IRT Pelham Line, and IRT Jerome Avenue Line. The Manhattan Bridge line described below later became the BMT West End Line, BMT Fourth Avenue Line, the BMT Sea Beach Line, and the Nassau Street loops.[41][42]

The route of the new subway ... comprises a main trunk north and south through Manhattan Borough on Lexington Avenue and Irving Place from the Harlem River to Tenth St. and on Broadway, Vesey and Church Sts. from Tenth St. to the Battery; two branches in Bronx Borough, one northeast via 138th St. Southern Boulevard and Westchester Ave. to Pelham Bay Park. the other northerly via River Ave. and Jerome Ave. to Woodlawn Road, connecting with the Manhattan trunk by a tunnel under the Harlem River; a Manhattan-Brooklyn line extending from the North River via Canal Street across the East River on the Manhattan Bridge to connect with the Fourth Avenue subway in Brooklyn now being built, which thus becomes an integral part of the larger system; two branches southerly from the Fourth Ave. line extending south to Fort Hamilton and southeast to Coney Island; and a loop feeder line in Brooklyn through Lafayette Ave. and Broadway, connecting with the Fourth Ave. line at one end. and at the other crossing the Williamsburg Bridge and entering the Centre Street Loop subway in Manhattan which is thus also incorporated in the system.

In 1911, William Gibbs McAdoo, who operated a competing subway company called the Hudson & Manhattan Railroad, proposed building a line under Broadway between Hudson Terminal and Herald Square.[43] He later proposed that the Broadway line be tied into the IRT's original subway line in Lower Manhattan. The Broadway line, going southbound, would merge with the local tracks of the IRT Lexington Avenue Line in the southbound direction at 10th Street. A spur off the Lexington Avenue Line in Lower Manhattan, in the back of Trinity Church, would split eastward under Wall Street, cross the East River to Brooklyn, then head down the Fourth Avenue Line in Brooklyn, with another spur underneath Lafayette Avenue.[44]

The Triborough System later became part of the Dual Contracts, signed on March 19, 1913 and also known as the Dual Subway System. These were contracts for the construction and/or rehabilitation and operation of rapid transit lines in New York City. The contracts were "dual", in that they were signed between the City and the IRT and Municipal Railway Company, a subsidiary of the BRT (later BMT).[45]

Some lines proposed under the Contracts were not built, most notably an IRT line to Marine Park, Brooklyn (at what is now Kings Plaza) under either Utica Avenue, using a brand-new line, or Nostrand Avenue and Flatbush Avenue, using the then-new IRT Nostrand Avenue Line. There were also alternate plans for the Nostrand Avenue Line to continue down Nostrand Avenue to Sheepshead Bay.[46]

Design

Lines designed to be used for higher capacity rolling stock than the IRT; unclear operator that would operate them

[47]

Dual Contracts

edit

 
The original "H" system that predated the contracts

The Dual Contracts, signed on March 19, 1913, also known as the Dual Subway System, were contracts for the construction and/or rehabilitation and operation of rapid transit lines in the City of New York. Most of the lines of the present-day New York City Subway were built or reconstructed under these contracts. The contracts were "dual" in that they were signed between the City and two separate private companies (the Interborough Rapid Transit Company and the Brooklyn Rapid Transit Company), all working together to make the construction of the Dual Contracts possible.

Background

edit

In the late 19th century and for most of the 20th century, New York was host to millions of immigrants each year. Many of the immigrants crowded into tenements and other apartment buildings in the inner city. This resulted in overpopulation of the buildings, and congestion of city streets. Manhattan's population had risen from 516,000 people in 1850 to 2.33 million people just sixty years later.[48] Living in Manhattan was becoming a hazard due to the higher probability of crime and overcrowding, and for the most part, the first subway line only served areas that were already developed.[49] The first subway lines to the outer boroughs were planned during the early 20th century.[50] Dispersion resulted in the expansion and development of the boroughs, and helped prepare New York for the millions of immigrants that came in the following years.[citation needed]

In 1906, Charles Evans Hughes was elected as the governor of New York, and the next year, he created the New York State Public Service Commission (PSC). The PSC was responsible for new rapid transit lines in New York City. Although the PSC had created ambitions plans for the expansion of the city's subway system, they only had $200 million on hand (equivalent to $6,540,000,000 in 2023).[51] In 1911, George McAneny was appointed leader of the Transit Committee of the New York City Board of Estimate, which oversaw the subway expansion plans.[52]

Some opposed the Dual Contracts as they thought that the company owners and city officials were just looking for another way to produce personal revenue.[52] Reformists like Hughes and McAneny would not have it any other way than to see the expansion of the city and the subway. They wanted to see the inner city become less populated and spread the people to the outer boroughs of the city. They planned to expand the city and disperse the people by building subway lines which would hopefully result in new homes being built near the subway lines and the areas surrounding. This would lower population densities in the city and also made as a good reason to help prove the subway expansion as necessary.[citation needed]

Crowding

Before the Contracts, there was crowding in many of the forms of transportation in the city. The following is a list of annual ridership for each mode of transportation between June 30, 1910, and June 30, 1911:

  • Interborough Rapid Transit Company – subways, elevated roads — 578,154,088
  • Hudson and Manhattan Railroad — 52,756,434
  • Brooklyn Union Elevated Railroad System — 167,371,328
  • East River ferries — 23,460,000
  • Municipal ferry to Staten Island — 10,540,000
  • Hudson River ferries — 91,776,200

In total, 924,058,050 passengers were carried that year over these six modes of transport.[53]

Planned effects

edit

It was expected that, within five years of completion:

When completed the rapid transit facilities of the City will have been more than trebled. During the year ended June 30, 1911, shortly after which the construction of the new system was begun, the existing rapid transit lines carried 798,281,850 passengers. The new Dual System will have a capacity of upwards of [3 billion], although it is not expected that such capacity will be demanded immediately upon the completion of the system. The combined trackage of the existing lines (including 7.1 miles of the Hudson and Manhattan Railroad) amounts to 303 miles of single track. To this will be added by the new lines of the Dual System 334 miles of single track, making a new system with 637 miles of single track. What this will mean to the City may be appreciated by considering how the existing lines will be amplified by the new additions and extensions. The Hudson and Manhattan road, however, is not to be a part of the Dual System.[53]

This system expansion was expected to be as big as, if not bigger, than the proposed Second System expansion put forth by the Independent Subway System in 1929 and 1939.

The Contracts

edit
 
1910 plan for IRT expansion

Contracts 1 and 2

edit

Built before the Dual Contracts, the first regularly operated subway in New York City was built by the city and leased to the Interborough Rapid Transit Company (IRT) for operation under city Contracts 1 and 2. Until 1918, when the new "H" system that is still operated - with separate East Side and West Side lines - was placed in service, it consisted of a single trunk line below 96th Street with several northern branches. The system had four tracks between Brooklyn Bridge–City Hall and 96th Street, allowing for local and express service on that portion.

Contract 1 was for the original 28 stations of the subway system that opened on October 27, 1904, from City Hall to 145th Street, as well as for stations opened before 1908 on several IRT extensions. The original system as included in Contract 1 was completed on January 14, 1907, when trains started running across the Harlem Ship Canal on the Broadway Bridge to 225th Street,[54] and the Contract 2 portion was opened to Atlantic Avenue on May 1, 1908.[55]

Contracts 3 and 4

edit

On March 19, 1913, the Dual Contracts were signed between the City and the two private operators. Contract 3 was signed between the City and the IRT, who operated the subway that was built under Contracts 1 and 2. Contract 4 was signed between the City and the Municipal Railway Company, a subsidiary of the BRT (later BMT), formed especially for the purpose of contracting with the city for construction of the lines. Contracts 1 and 2 were the original subway contracts between the City and the IRT for the city's first subway. These contracts predated the Dual Contracts, which were contracts 3 and 4.[56]

Under the terms of Contracts 3 and 4, the city would build new subway and elevated lines, and rehabilitate and expand certain existing elevated lines, and lease them to the private companies for operation. The projected $366 million cost would be borne mostly by the City, which paid $200 million, and the companies would pay the difference.[57] The City's contribution was in cash raised by bond offerings, while the companies' contributions were variously by supplying cash, facilities and equipment to run the lines.

Queensboro Plaza

edit
 
Queensboro Plaza track plan

The contract negotiations were long and sometimes acrimonious. For instance, when the IRT was reluctant to the BRT’s proposed access to Midtown Manhattan via the Broadway Line, the city and state negotiators immediately offered the BRT all of the lines under proposal. This included lines that would have only been operable using IRT rolling stock dimensions, such as the upper Lexington Avenue Line and both lines in Queens. The IRT quickly gave in to the "invasion" of Midtown Manhattan by the BRT.[58][59]

The assignment of the proposed lines in Queens proved to be an imposition on both companies. Instead of one company enjoying a monopoly in that borough, both proposed lines — a short line to Astoria, and a longer line reaching initially to Corona, and eventually to Flushing — were assigned to both companies, to be operated in what was called “joint service.” The lines would start from a huge station called Queensboro Plaza. The IRT would access the station from both the 1907 Steinway Tunnel and an extension of the Second Avenue Elevated from Manhattan over the Queensboro Bridge. The BRT would feed the Queens lines from the 60th Street Tunnel in Manhattan. Technically the line was under IRT "ownership", but the BRT/BMT was granted trackage rights in perpetuity, essentially making it theirs also.[58][59]

The BRT had a big disadvantage, as both Queens lines were built to IRT specifications. This meant that IRT passengers had a one-seat ride to Manhattan destinations, whereas BRT passengers had to make a change at Queensborough Plaza. This came to be important when service was extended for the 1939 World’s Fair, as the IRT was able to offer direct express trains from Manhattan, and the BRT was not. This practice lasted well into the municipal ownership of the lines, and was not ended until 1949. Both companies shared in the revenues from this service. To facilitate this arrangement originally, extra long platforms were constructed along both Queens routes, so separate fare controls/boarding areas could be established. This quickly turned out to be operationally unworkable, so eventually a proportionate formula was worked out. The bonus legacy of this construction was that the IRT was able to operate 11-car trains on this line, and when the BMT took over the Astoria Line, minimal work had to be done to accommodate 10-car BMT units.[59]

Conditions

edit
 
The large Chambers Street station was the BMT's Manhattan hub.
 
The large Coney Island Terminal in Brooklyn was the BMT's largest terminal outside of Manhattan.
 
The IRT rebuilt the Steinway Tunnel, originally a trolley tunnel, for subway use.

Several provisions were imposed on the companies, which eventually led to their downfall and consolidation into city ownership in 1940:

  • The fare was limited to five cents; that led to financial troubles for the two companies after post-World War I inflation. The BMT could charge ten cents for fare to Coney Island Terminal, as well as to stations "where such ten cent fare is now allowed, until the time when trains may be operated for continuous trips over wholly connected portions of the railroad" between Coney Island and the Chambers Street station in Manhattan.[60]
  • The City had the right to "recapture" any of the lines it built and run them as its own.[60]
  • The City was to share in the profits.[60]

There were other conditions in regards to specific operations of the lines, as part of a deal between the IRT, the BMT, and the Public Service Commission. Many of the conditions applied all across the dual system. For example:

  • After the Commission finished constructing the line, the company was to operate it, providing its own rolling stock and furnishings.[60]
  • The companies, if they operated lines temporarily, had to operate them as if they were subway extensions. For subway extensions, if a company accepted the extension, it could operate it as part of its system; if not, the company had to pay a significant amount to the city every three months to operate it. This was implemented as part of the Queensboro Plaza trackage-sharing operation.[60]
  • The companies had operate these lines "according to the highest standards of railway operation and with due regard to the safety of the passengers and employees thereof, and of all other persons."[60]
  • Free transfers would be given at stations where needed, such as transfer stations between lines of the IRT and BMT, bus–subway transfer stations, elevated–subway transfer stations, or streetcar–subway transfer stations, according to the Commission's discretion.[60]
  • Freight, mail and express trains could use these companies' tracks if they did not disrupt passenger operations.[60]
  • Advertising was prohibited in stations, railroad tunnels, elevated structures, or other places. Bulletins telling of service changes were allowed.[60]
  • Selling things in the stations was prohibited, except if it needed for the operation of the subway, or if it was a newspaper, periodical, or magazine that the Commission had permitted.[60]
  • Each company was to post their intentions to operate newsstands in the form of proposals to the Commission.[60]

Some conditions applied only to certain parts of the system:

IRT lines

edit

Under the original "H" system, the original line and early extensions built for the IRT are:

The following lines were built under the Dual Contracts for the IRT:[53]

The following lines were rebuilt with extra tracks:[53]

Some of the IRT lines proposed under the Contracts were not built. Most notably, there were plans to build an IRT line to Marine Park, Brooklyn (at what is now now Kings Plaza) under either Utica Avenue, using a brand-new line, or Nostrand Avenue and Flatbush Avenue, using the then-new IRT Nostrand Avenue Line. There were also alternate plans for the Nostrand Avenue Line to continue down Nostrand Avenue to Sheepshead Bay.[61]

BMT lines

All Manhattan and Queens BMT lines were built under the Dual Contracts, as were all subway and some elevated lines in Brooklyn.[53]

Lines and line segments built new

edit

The most important of the lines the the BRT got built as part of the Dual Contracts was the Broadway Line. In the Dual Contracts, the line was merged with the Fourth Avenue Line, collectively being called the Broadway–Fourth Avenue Line. The line would start at an elevated complex at Queensborough Plaza as a two-track line. The line was then planned to go over the Queensborough Bridge before going underground, with one track going under 59th Street and one via 60th Street to Fifth Avenue, where the two tracks would converge and continue as a two-track line until 59th Street and Seventh Avenue. From here, the line would turn southward as a four-track line. The line would run via Seventh Avenue and then Broadway to Canal Street. This would make up Subdivision I. Subdivision II, would have a line over the Manhattan Bridge built. It would start at Canal Street near Broadway, with a connection to Subdivision I, and continue under Canal Street until the approach to the Manhattan Bridge, where the line would become four tracks. Across the bridge, at Nassau Street and Flatbush Avenue Extension, the line would go underground, continuing until Willoughby Street.[56]: 287 

The third section, Subdivision III, would extend the first section into Lower Manhattan. From Canal Street, the line would continue as a four-track line until Park Place, where it would become two tracks. North of Vesey Street, the line would turn west under private property to Church Street and Trinity Place. After going via these streets, at Morris Street, the line would go east under private property to Whitehall Street, and thence to the East River. The next section of the line would be today's Nassau Street Line, or Subdivision IV. It would start in Lower Manhattan from Subdivision III under the East River. The two-track line would run under South Street, Broad Street, and Nassau Street to Park Row. Then, the line would go via Park Row to a point underneath the Municipal Building. The line would then be a four-track line under Centre Street until Walker Street. Here, the two easternmost tracks would split off, going under private property and Walker Street to Canal Street, from where the line would go over the Manhattan Bridge, with a connection to Subdivision II. The two-westernmost tracks under Centre Street would become four tracks, and would continue going north until Broome Street, from where, the line would curve under private property to Kenmare Street. After running under Delancey Street, the line would become a two-track line, going over the Williamsburg Bridge before meeting up with the Broadway Elevated. Subdivisions III and IV would be extended as Subdivision V under the East River through the Montague Street Tunnel, Montague Street and Court Street before going under public property, Fulton Street, and private property before going underneath Willoughby Street. Finally, the line would reach Flatbush Avenue Extension.[56]: 287–288 

As part of the Dual Contracts, two elevated lines that were operated by a subsidiary, the New York Consolidated Railroad, of the BRT, the Broadway Line and the Fulton Street Line, were extended. The Broadway Line, prior to the Dual Contracts, had extended to Cypress Hills, where it had terminated since 1893. The line was to be extended to Grand Street (now 168th Street) in Jamaica, Queens, and would then be known as the Jamaica Line. The line was constructed with two tracks and space for a third track that could be used for express service. The Fulton Street Line had ended at the border of Brooklyn and Queens at Grand Street since 1894. The line was then extended as a three-track line along Liberty Avenue to Lefferts Avenue (now Lefferts Boulevard) in Queens as the Liberty Avenue Line.[56]: 258 

Grade-separated rights-of-way built to replace surface railroads

edit

Existing rights-of-way rehabilitated and expanded

edit

As part of Contract 4, the Brooklyn Rapid Transit Company was authorized to install center express tracks on three elevated structures: the Myrtle Avenue Line, the Jamaica Line, and the Fulton Street Line. The Jamaica Line was expanded to three tracks from two from Marcy Avenue to Broadway Junction. The Myrtle Avenue Line was expanded from two to three tracks from Broadway–Myrtle to Myrtle–Wyckoff Avenues, including the addition of a track connection to the Jamaica Line. Finally, the Fulton Street Line was expanded to three tracks from Nostrand Avenue to east of the split from the Canarsie Line at Pitkin Avenue. Additionally, a new flying junction complex with six tracks replaced two tracks between the former Manhattan Junction in East New York and Pitkin Avenue. This portion gave the Canarsie Line two dedicated tracks.[56]: 229–231

Effects

edit

As reformists predicted the Dual Contracts resulted in city expansion. People moved to the newly built homes along the newly built subway lines. These homes were affordable, about the same cost as the houses in Brooklyn and Manhattan.[57] The Dual Contracts were the key to dispersion of the city’s congested areas. The Dual Contracts helped lower high population areas and probably helped saves lives as people were no longer living in heavily diseased areas. According to the Federal Census of New York City for 1920 the population in Manhattan below 59th Street decreased from 1910 to 1920. The census resulted in the following:

  • 1905 State census: 1,271,848
  • 1910 United States census: 1,269,591
  • 1915 State census: 1,085,308
  • 1920 United States census: 1,059,589[62]

People were allowed to move to better parts the same cost and could have a better and more comfortable life in the suburbs. They could still commute to work every day as most of the better off city workers who moved to the outer boroughs did.[57] This also helped the business districts as people could still work.
