The Thomas A. Edison Bridge is an important example of a very large and early continuous deck plate girder highway bridge. It was the largest, highest, and longest span bridge of its type in the United States when completed. Its erection by the Bethlehem Steel Company involved the lifting of the world's longest (260') and heaviest (198 tons) girder to a height of 135'. Morris Goodkind made important contributions to twentieth-century highway bridge engineering.

Something seems off on the location; the coordinates are pointing to Driscoll Bridge, which is much, much larger.
