The two main spans are dissimilar- one pin-connected Pratt through truss, one riveted camelback Pratt through truss. There are also two subdivided Warren pony truss spans leading to the main spans.
It appears that this bridge was constructed at least partially of older parts moved in. the pin-connected Pratt span almost certainly predates 1940.
Length of largest span: 100.1 ft.
Total length: 334.0 ft.
Deck width: 15.1 ft.
