Brief Description:

The CTA's® first newly designed rapid transit line, the Congress Line, opened in June 1958 and pioneered a new, completely divergent philosophy of station (and indeed, route) design. The Congress Line, or "West Side Subway" as it was also called in its early years, was built to replace the 50+ year old Garfield Park elevated, whose removal was required by the construction of the Congress Superhighway (later called the Eisenhower Expressway, Interstate 290). The new, replacement line followed an innovative new concept: putting a rapid transit line in the center of an expressway.
