Lake is an "L" station on the CTA's Red Line in the Chicago Loop that is part of the State Street subway. Lake is a transfer station between the Red Line and the Brown, Green, Orange, Pink, and Purple Lines at the State/Lake station and the Blue Line at Washington via the Chicago Pedway. In 2019, Lake had an average of 19,364 weekday passenger entries, making it the busiest 'L' station.[2]
On November 20, 2009, the Chicago Pedway connecting the unpaid portions of Lake and Washington stations reopened to service.[3]
This station was originally part of the closed Washington station. The two were separated on June 2, 1996, due to the renovation project of the Randolph-Washington mezzanine and Lake became an independent station on November 18, 1997, in order to better facilitate transfers between the Red Line subway and the elevated State/Lake station.
