Steel construction recently began on the main arch span of the Modjeski and Masters-designed Portageville Bridge across the Genesee River in Letchworth State Park. The Portageville Bridge, also known as the High Bridge, is considered to be the vital link along Norfolk Southern Corporation’s Southern Tier Route, a railroad line that runs between Binghamton and Buffalo, New York.
Built in 1875, the historic 820-foot steel viaduct can no longer meet the demands of a Class 1 Heavy Freight Railroad. Construction to replace the bridge began in 2015. To date, construction has been focused on the preparation of the foundations and approach piers, which has included blasting of the gorge walls.
