Two rare Strauss vertical overhead counterweight bascule bridges sit next to
each other at this location. In the photos provided here, a nice comparison is
offered, with one bridge raised and the other one lowered. Vertical overhead
counterweight bridges were designed by Joseph Strauss for small bascule bridges,
under 100 feet in span length and typically featured plate girder leaves. For
larger bascule bridges, his company designed heel-trunnion bascule bridges,
which typically featured truss leaves.
Today, only the southern bridge remains in use by trains.
