It now sits in a village-owned park.","why_significant":"The nomination cites Criterion A for transportation, as a bridge of the Genesee Valley rail line linking farms and industries to Rochester markets. It cites Criterion C as an excellent example of a mid-nineteenth century masonry arch railroad bridge, built by the noted railroad contractors Phelps, Mattoon & Barnes.","narrative":"Spanning Conesus Outlet Creek in Avon, New York, this limestone railroad bridge was built between 1856 and 1857 as part of the line connecting Rochester, Avon, Geneseo and Mount Morris. It is about 200 feet long, twelve feet wide and roughly thirty feet high, with five elliptical arches of rusticated coursed ashlar, three of whose piers rest in the creek bed. Timber braces were added over the arches in the late nineteenth century to cope with heavier locomotives, and a concrete cap was added when the rail gauge changed. The railroad firm Phelps, Mattoon & Barnes built it to help farms and small industries reach markets in Rochester. Trains stopped crossing it in 1941, and the Village of Avon bought it in 1971 for use as a park. Volunteers repaired it in 1992, and a 2009 report found the stonework in good condition. It is considered significant for its role in regional transportation and as a fine example of masonry arch construction.","period_of_significance":"1856-1857","architect_builder":"Phelps, Mattoon & Barnes","architectural_style":null,"criteria":["A","C"],"status_note":"The rail line was abandoned in 1941 and the bridge was acquired by the Village of Avon in 1971; it is now part of a village park.
