Elevated station (1895–1992)

The original elevated station opened on September 22, 1895 as one of three stations on the Lake Street Elevated Railroad's "Wabash extension". This extension became the Lake Street leg of the Union Loop when it was completed in 1897.

Subway station (1951–1992)

The subway station opened as Lake Transfer on February 25, 1951.

Combined station (1992–present)

From 1988 to 1992, the elevated station was reconstructed, with its main entrance in the James R. Thompson Center. This allows transfers between the elevated station and the subway station without leaving the paid area, and so the stations were combined into a single station. Due to this, it is the only station that serves six of the eight lines. The Blue Line serves the subway station while the Green Line stops at both sides of the elevated station, Orange, Pink and Purple Line trains stop at the Inner Loop platform, and Brown Line trains stop at the Outer Loop platform.
