The bridge is long and high from water level to the top of the rail, and is composed of five spans and two spans. The footings were excavated down to bedrock, which ranges from to below the surface.Cohen, A. B. "The Delaware River Viaduct." Purdue Engineering Review, No. 6 (1909-10): 13. A total of of concrete and 627 tons of reinforcing steel were used to construct this bridge.

Construction of the bridge was described in an article by Abraham Burton Cohen, then a draftsman for the Delaware, Lackawanna and Western Railroad, who later went on to design the Tunkhannock Viaduct, an even larger structure on the railroad's Summit-Hallstead Cutoff.Cohen, A.
