There are two fare-card only, unattended entrances atop two long stairways accessed directly from Wells Street, just north of Kinzie Avenue.

There are two side platforms both long enough to support eight-car trains, the longest possible on the CTA system.

Kinzie was a station on the Northwestern Elevated Railroad's North Side Main Line.

The primary purpose of the station is to serve the Merchandise Mart, one of the world's largest commercial buildings, although there are some galleries and restaurants nearby.

Because of its recent construction from 1987 to 1988, the station is accessible to passengers with disabilities and is already of sufficient length to accommodate eight-car trains, thus no major renovation was needed during the project.
