It is located in the median of I-190 with one island platform serving two tracks, 16 miles (26 km) northwest of The Loop.

[2] The Rosemont station opened on February 27, 1983, as the terminus of an extension of the West-Northwest route from its former terminal at Jefferson Park.

The station name was changed in the mid-1990s, around the same time that the Dempster–Skokie and Des Plaines terminals on the Yellow and Blue Lines were renamed to reflect the suburb they serviced rather than the cross street.

In addition, there is a parking lot for commuters that costs $7 USD for 14 hours of allowed time.

Just west of the station is a maintenance facility built in a wide spot of the freeway's median.
