This bridge is known locally as the Nicholson Bridge because it located in Nicholson, Pa. on Routes 11 and 92.
It was built from 1912 to 1915 as part of a major improvement to the Delaware, Lackawanna and Western Railroad. It is 2,375 feet long, 34 feet wide and 240 feet at it's highest point above Tunkhannock Creek.
At the time it was built it was the largest reinforced structure of it's kind and is the world's largest concrete railroad bridge.
Novelist Theodore Dreiser called this viaduct "One of the true wonders of the World."
To truly appreciate the size of this structure you really should see it other than in photographs.
