The Genesee Arch Bridge (also known as the Portage Viaduct or Portage Bridge) is a steel arch railroad bridge over the Genesee River in Letchworth State Park, Livingston County, New York. It is the third bridge at this location: the original timber bridge burned in 1875 and was replaced by an iron bridge, which lasted until it was replaced by the current bridge in 2017. It carries the Southern Tier Line of Norfolk Southern Railway.[1]
