History

The South Side Elevated Railroad, the first rapid transit company in Chicago, opened on June 6, 1892, with ten stations, one of which was located on 18th Street. Eight of the ten stations on the line were built with street-level station houses.

In 1907, the railroad was allowed by the city to construct a third track for express operations. In exchange, it promised to demolish the station houses north of 43rd Street, including all of the original street-level station houses, and replace them with mezzanines in order to clear the alleyway below the track.
