Washington Crossing Bridge
Significance: The bridge is an outstanding example of a long-span metal deck arch bridge. Its unique architectural details, forged in a successful collaboration between architects and engineers in the design and construction of the bridge, add to its significance. The bridge is also significant because its construction was the culmination of a conflict over Allegheny River bridge heights between the U.S. War Department and local governments.
