Asylum Bridge

Posted February 28, 2008, by Robert L. Elder (Robertelder1 [at] gmail [dot] com)

The center span of this bridge is actually a Parker Truss with the top chords inverted so they "dip" towards the center of the span, hence the term Reverse Parker. This is easier seen in a side view of the bridge. This bridge is believed to be the only Reverse Parker Truss in existence.

Looks like a small cantilever bridge to me, ie a continuous through truss. Stylistically similar to the Thamesville Bridge in Ontario. I am not familiar with the term "reverse parker" unless this was an early term to describe cantilever technology.

This is a Reverse Parker through truss. This may possibly be the only example of Reverse Parker in existance.
