The nearest metropolitan centers accessible on I-74 are the Quad Cities to the west, and Bloomington-Normal to the east.

In addition, U.S. Route 150 serves as the main arterial for the northern portion of the Peoria area, becoming War Memorial Drive before heading west towards Kickapoo. It enters from the McClugage Bridge; east of the bridge, then runs southeast to Morton. U.S. Route 24 runs concurrently with Interstate 474 in the southwest portion of the city.
