Heading northeast from exit 47 of the New York State Thruway (I-90), I-490 passes through rural portions of eastern Genesee County and western Monroe County, skirting the villages of Bergen and Churchville. Gradually, the expressway takes a more easterly alignment near exit 3 before returning to the northeast at exit 4. At exit 6, I-490 intersects the Airport Expressway (NY 204). Past this interchange, I-490 heads due north, connecting to NY 33 and NY 531 before returning east. Prior to crossing the Erie Canal, I-490 meets NY 390 and I-390. Beyond the junction lies the canal and the city of Rochester.
