From Wikipedia:

Tunkhannock Viaduct

Tunkhannock Creek Viaduct (also known as the Nicholson Bridge and the Tunkhannock Viaduct) is a concrete deck arch bridge on the Nicholson Cutoff rail line segment of the Norfolk Southern Railway's Sunbury Line that spans Tunkhannock Creek in Nicholson, Pennsylvania.

Opened by the Delaware, Lackawanna and Western Railroad (DL&W) in 1915, the bridge is used daily for regular through freight service.

The bridge measures 2,375 feet (724 m) long and towers 240 feet (73.15 m) above the creek bed; it stands 300 feet (91.44 m) above bedrock. It was the largest concrete structure in the world at its completion; a half-century later, it still merited "the title of largest concrete bridge in America, if not the world".

In 1975, the American Society of Civil Engineers designated the bridge as a National Historic Civil Engineering Landmark. The bridge was listed on the National Register of Historic Places on May 3, 1977.
