The Tunkhannock Viaduct in the town of Nicholson, PA, near Scranton, was completed by the Delaware, Lackawanna and Western Railroad in 1915. It is the largest reinforced concrete structure in the world. It is still used today by the Canadian Pacific Railway. It stretches for 2,375 feet across ten 180-foot arches and two 100-foot arches. It consumed about 350,000 tons of concrete and 1,140 tons of reinforcing steel.
