The bridge, 2,375 feet long and rising 240 feet above Tunkhannock Creek, was the focal point of a 39.6 mile relocation between Clarks Summit and Hallstead.

1. Once the Largest Concrete Structure in the World:
When the Delaware, Lackawanna and Western Railroad (DL&W) rerouted and straightened its main line in the early 1900s, the resulting realignment required deep cuts, high embankments, and massive bridges. Named for the creek it crosses, the Tunkhannock Viaduct, also known as Nicholson Viaduct because it towers above the town of Nicholson, north of Scranton. At one time it was the largest reinforced-concrete structure in the world.
At the dedication ceremonies on November 6, 1915, Pennsylvania Governer Martin C. Brumbaugh compared the Tunkhannock Viaduct to the Walnut Lane Bridge over the Wissahickon Creek in Philadelphia's Fairmount Park which, when it opened in December 1908, was hailed as the largest concrete bridge in the state. Walnut Lane's main span measured 233 feet long and rose 147 feet over the valley. You could put a dozen Walnut Street bridges under this monster and not notice them.”
