Lake station (CTA)

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 Blue via the Chicago Pedway. In 2019, Lake had an average of 19,364 weekday passenger entries, making it the busiest 'L' station.

Lake is linked to Millennium Station and Millennium Park via a Chicago Pedway connection that can be accessed at its Randolph–Washington exit.

On November 20, 2009, the Chicago Pedway connecting the unpaid portions of Lake and Blue stations reopened to service.

This station was originally part of the closed Red 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.
