The road enters western suburbs River Grove and Franklin Park before the main segment ends with other parts of Belmont still going west.

The park's property is now home to the Riverview Plaza shopping center, the Belmont District Police Station, and DeVry Institute of Technology.

One of the landmarks on Belmont Avenue was the Bally Manufacturing Corporation complex located between Washtenaw and Rockwell.

Bally moved manufacturing and eventually the corporate office to the west side of Chicago and to the western suburbs of Bensenville and Franklin Park starting in the late 1970s.

The street was named in memory of the Battle of Belmont during the American Civil War that was fought on November 7, 1861, in Mississippi County, Missouri.
