Description 

This bridge was built on what was once the main north-south route in the area, replacing an existing wooden stringer bridge. Ironically, the new bridge built in 2007 to replace this truss is a wooden bridge of modern laminated treated lumber!

This is very interesting because they made replica caissons.
