Chicago "L" station
Washington is an 'L' station on the CTA's Blue Line. It is situated between the Clark/Lake and Jackson stations in the Milwaukee-Dearborn subway and is near the Richard J. Daley Center.
History
Washington opened on February 25, 1951, as part of the Milwaukee-Dearborn subway, the second of two subways to be constructed in Chicago. The station was entirely renovated from 1982 to 1984. As constructed, the station has two closed stairways to a lower level pedestrian transfer tunnel to the closed Washington station in the State Street subway. At midnight on October 23, 2006, the lower level transfer tunnel to the Red Line closed as part of the construction of a planned superstation under the Block 37 mall. On November 20, 2009, the pedway linking the Lake station's unpaid area to that of Washington reopened [2] and beginning in May 2013, the CTA provided a farecard transfer through the pedway between the stations.[3]
This is the northernmost of the three stations on one long continuous platform underneath Dearborn Street, with the stops at Monroe and Jackson being the other two.
