Oak Park was nearly identical to every other station built in the Eisenhower Expressway, including an island platform, small station houses on Oak Park's overpass containing only a ticket booth and turnstiles and a long, enclosed, sloping passageway/ramp connecting the two.

Each street-level station entrance was identified by a large, electrically illuminated sign (since removed from all Congress stations). This type of advertising was far more proactive than anything posted in front of most stations previously, although this may have been a requirement, in part, necessitated by the removal of the station entrance from the surrounding neighborhood and its isolation in the middle of the expressway, coupled with the invisibility of the tracks and trains themselves, hidden in the open cut. The buildings were small compared to many older stations, about 42 feet long and 21 feet wide, and provided only the most minimal, necessary amenities. Exterior walls were a combination of glazed brick and structural glass blocks. Station entrance facades were a combination of aluminum panels, polished plate glass windows, and aluminum framed plate glass doors. The use of a glass front, which provided increased visibility into the station from the street and vice versa was a new concept that would be further explored in the CTA's next generation of median stations in the Kennedy-Dan Ryan project. The station exteriors were largely devoid of the type of ornamentation seen in the previous 50 years of station design, save perhaps for the door handles on all Congress stations, which were molded in the shape of the CTA logo. Recalling that the platform is set between two streets a quarter mile apart, there is a rather long distance that needs to be traversed between the station houses and the platforms in between. Thus, connection between the station houses and platform was achieved using long, enclosed ramps from the back of the station houses to the ends of the platform.

Oak Park featured an auxiliary entrance at East Avenue. The East entrance featured an even smaller station house with an agent's booth, a single agent-controlled turnstile, and an exit rotogate. In later years, the station house was remodeled and the original booth and fare controls were removed. Farecard-only High-Barrier Gate (HBG) turnstiles have been installed to allow unmanned entrance through East at all times. Unlike the long ramp at the Oak Park entrance (and most Congress entrances), East is connected to the platform by a set of stairs and a track-level walkway protected by fencing to the east end of the platform.
