Leaving the Inner Loop, Interstate 490 follows the West Expressway to the exchange with I-390 (Outer Loop freeway) south to ROC Airport and NY 390 north to Greece. Continuing west through Gates, I-490 splits with NY 531, a freeway spur leading toward Spencerport and Brockport. I-490 turns south from NY 531 to Chili and west again ahead of Churchville. The western end at the New York Thruway falls within a rural area south of Bergen and north of Le Roy.

As part of the Western Gateway Project reconstructing Interstate 490 from I-390 east to Downtown Rochester, the aging Troup Howell Bridge was replaced with a signature span featuring three 70 foot high arches. Work on the crossing, which spans the Genesee River at a height of 85 feet, commenced in April 2004 and was completed on June 18, 2007. The bridge was subsequently renamed the Frederick Douglass-Susan B. Anthony Memorial Bridge in July 2017.
