Description 

FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY: The 1921, 750'-long viaduct has a riveted, 176'-long, Parker thru truss main span and 8 thru girder, deck girder, and adjacent box beam approach spans. The last are replacements dating from 1977. The safety shape parapets and cantilevered sidewalk with modern steel railing date to 1984. The viaduct uses common technologies and has no innovative or distinctive details. Nor is it significant in association with the former Pennsylvania Railroad main line, because the viaduct was built as a highway oriented project meant primarily to improve vehicular traffic flow, not by the railroad to increase the efficiency of its operations. The viaduct is neither historically nor technologically significant.

Lest we forget: Michael Strank was the leader of the Marines photographed raising the flag on Iwo Jima. He died ten days later.
