The Inner Loop forms a "C" around downtown Rochester, beginning, from west to east, at I-490 exit 13, a directional T interchange adjacent to Frontier Field, the home of the Rochester Red Wings. It heads to the northeast, passing Frontier Field and the High Falls business district as it runs parallel to the CSX Transportation-owned Rochester Subdivision railroad line. About from I-490, the Inner Loop and the Rochester Subdivision both cross the Genesee River just south of where the river goes over High Falls. On the other side of the river, the highway turns toward the east, separating from the railroad a short distance southwest of Rochester's Amtrak station on Central Avenue. This is also the location of the first exit on the Inner Loop heading east—with Saint Paul Street and Clinton and Joseph Avenues—and is the beginning of the frontage roads that run parallel to the loop along its length.
