Built in 1856-57 by the Genesee Valley RR to span the Conesus Outlet, the 200 ft. long x 12 ft. wide limestone bridge was part of the Rochester-Avon-Geneseo-Mt. Morris Line. Avon became a RR hub connecting Buffalo-Rochester-Corning-Hornell. The line was electrified in 1907, with 13 runs daily between Rochester and Mt. Morris. In 1941 the Avon-Mt. Morris section was abandoned and the rails removed.
