Abstract: Since 1852, the Portage Viaduct has carried a rail line across the Genesee River Gorge, near the town of Portageville, New York. First made of timber, then replaced with a wrought iron structure after a destructive fire, the crossing became an icon for the community. Tasked with replacing the viaduct, bridge engineering firm Modjeski and Masters worked with the community and the Norfolk Southern Railway Co. to create a new iconic arch bridge for the gorge.
