Location

The Delaware River Viaduct is a reinforced concrete railroad bridge across the Delaware River about two miles (3.2 km) south of the Delaware Water Gap that was built from 1908 to 1910 as part of the Lackawanna Cut-Off rail line. It is the sister to the line's larger Paulinskill Viaduct. The Delaware River Viaduct also crosses Interstate 80 on the east (New Jersey) side of the river and Slateford Road and the Lackawanna Railroad's "Old Road" (now Delaware-Lackawanna) on the west (Pennsylvania) side. Abandoned in 1983, it is part of an Amtrak proposal to introduce passenger service between Scranton, Pennsylvania and New York City, a distance of 135 mi (217 km).

The bridge is 1,452 feet (443 m) long and 65 ft (20 m) high from water level to the top of the rail. It is composed of five 150 ft (46 m) spans and two 120 ft (37 m) spans. It was considered the largest reinforced concrete structure in the world when it was completed in 1910.^[1]
