The hill to hill bridge is located in Bethlehem, Pennsylvania. The bridge carries PA 378 over the Lehigh River and connects the north and south sides of Bethlehem. It was built in the 1920s and is made up of a concrete arch (pictured above) and a truss (barely seen to the right in the photo).
Just upstream of the hill to hill bridge, there’s an old railroad truss bridge (still active, I believe).
