Bridge Documentation

This bridge no longer exists!

Bridge Status: Demolished and replaced.

This bridge is one of two similar truss bridges in the area. The other is the Beaverdams Road Bridge, which has one pony truss spans instead of two.

Supports for the bridge appear to be an unusual combination of concrete and steel caisson. Original lattice railings are present on the bridge. There is a concrete slab approach span at each end of the bridge. A collapsed concrete road that appears to have led to a preceding bridge remains just west of the bridge. A person can walk out on this road and get nice views of the bridge. There is a sign on this old road alignment that warns people that the sediment in Lake Gibson is polluted and toxic.

This bridge retains good historic integrity with no significant alterations to its original materials and design. Its trusses offer a geometric beauty not found in modern bridges. The trusses are composed of built-up beams that are riveted and include v-lacing and battens, which only adds to the geometric art of the bridge. There is v-lacing on the diagonals and under the top chord and end post.

This bridge has been owned by Ontario Power Generation. After this bridge was demolished and replaced, following that project, the bridge is owned by Niagara Region. It would have been nice instead to see the bridge rehabilitated. The number of riveted truss bridges in the Niagara Region has been dropping rapidly, and there are plans for demolition of a number of bridges.
