For the next mile (1.6 km), I-390 follows a more northwesterly alignment along the northeastern edge of the Greater Rochester International Airport grounds. It meets Brooks Avenue (NY 204) at the northern edge of the grounds before leaving the airport area and curving more to the north, matching changes in the Erie Canal's alignment as both entities proceed around the southwestern edge of the city. Now in Gates, I-390 crosses over the Rochester and Southern Railroad just south of another partial cloverleaf interchange with NY 33A. The freeway continues on, passing under the CSX Transportation-owned Rochester Subdivision and NY 33 before connecting to I-490 at a complex interchange roughly west of the canal and the city limits. I-390 ends here; however, the freeway continues northward toward Greece as NY 390.
