Actually, they are two different types. This bridge is a cantilver (also known as a continuous) truss bridge. The Asylum Bridge is a very rare style known as a Reverse Parker. If you look carefully at the middle portion of the Asylum Bridge, you will notice that it resembles a Parker Truss, only with the top chords inverted. The Asylum Bridge is thought to be the only one of its kind in existence.

This bridge looks like a newer version of the Asylum Bridge.
Do you think its the same truss type, and are there any connections between the two?
