It is located at Oak Park Avenue and South Boulevard in the village of Oak Park, Illinois and is the closest station to the Frank Lloyd Wright Home and Studio.

Both lines created an unsafe grade crossing, especially as the community moved from horse-powered vehicles to the automobile.

On October 28, 1962, the station was elevated on an embankment and the main entrance was rebuilt by taking advantage of the small space along the road to include a ticket window and enclosed waiting rooms.

When the Green Line closed for a renovation project in 1994, the CTA had planned to permanently close the Oak Park station along with four other stations (Austin, Laramie, Homan and Halsted).

However, due to the political pressure and complaints of residents, the station was retained without being rebuilt and reopened with the Green Line on May 12, 1996.
