Description
The original
bridge was a two-track, deck truss structure of seven fixed spans andone-center pier movable span with two deck plate girder approach spans on
the west end. The trusses on the west end were in good condition and were
not restored at that time. The piers were widened on both sides by building
on to the existing masonry, and the two additional trusses needed for
four tracks were erected on the outside of the present trusses. On the east
end, however, the old trusses were taken down and new piers were built for
three spans identical with those on the east end. AS copied from "NATIONAL REGISTER OF HISTORIC PLACES
