Route description
edit
I-190 begins as West Boulevard and has an intersection with Omaha Street, which is signed as US 16/South Dakota Highway 44 (SD 44). US 16 westbound goes east on Omaha Street and eastbound runs north concurrently with I-190. I-190 then becomes a freeway, with an exit to North Street. I-190 then passes under Anamosa Street before an onramp from the northbound lanes of West Boulevard. Both US 16 and I-190 then terminate at a trumpet interchange with I-90/US 14/SD 79.[3]
State law
editLegally, the route of I-190 is defined at South Dakota Codified Laws § 31-4-203.[4]
History
editA freeway replacing West Bypass to connect downtown Rapid City to I-90 was proposed by the city government.[5] The designation of I-190 for this connector was approved by the American Association of State Highway Officials in November 1958.[2]
I-190 was opened in 1962 to connect Rapid City to the recently completed I-90 bypass, which was built outside of Rapid City's northern boundaries.[6]
The interchange with I-90 was rebuilt from 2000 to 2001, changing from a directional T interchange with a left exit to a trumpet interchange.[7][8][9] The Omaha Street intersection was rebuilt in 2004,[10] while the North Street interchange was converted to a single-point urban interchange in 2017.[11]
Exit list
editThe entire route is in Rapid City, Pennington County.
