Opened to operations in 1915, the railroad bridge was at that time, the largest concrete bridge in the United States. Concrete was a rather new method of construction at the time, and many doubted the structure's integrity. Well for another 50 years the bridge continued to maintain its noteriety as the largest in the U.S. and was even considered to be the 9th wonder of the World by some. In 1977 the bridge was placed on the National registry of historic places.
Today the viaduct is still in use, helping to transport goods through northern Pennsylvania, as well as southern New York. And the bridge still serves as an essential component to tourism in a tiny mountain town in northeast Pennsylvania. Driving into the area as you witness the quiet town in the foreground, the massive infrastructure nearly takes your breath away.
