Route description
editSR 283 begins at an intersection with SR 281 at its interchange with I-90 northeast of George.[3] The two-lane highway travels due northeast through farmland in rural Grant County, passing Grigg Farm Airport and crossing over the Winchester Wasteway, before ending at an intersection with SR 28 southwest of Ephrata.[4][5]
Every year, the Washington State Department of Transportation (WSDOT) conducts a series of surveys on its highways in the state to measure traffic volume. This is expressed in terms of annual average daily traffic (AADT), which is a measure of traffic volume for any average day of the year. In 2011, WSDOT calculated that between 2,100 and 2,500 vehicles per day used the highway to travel between George and Ephrata.[6]
History
editSR 283 was created during the 1964 highway renumbering as the successor to the George–Ephrata branch of PSH 7.[7][8] The branch, created in 1949 to connect Ephrata to U.S. Route 10 (US 10),[9] was built and paved as a two-lane highway in the 1950s.[10] The bridge over Winchester Wasteway was built in 1953 and replaced with a newer concrete bridge that opened in April 2006.[11]
Major intersections
editThe entire highway is in Grant County.
