Main Street Bridges over Fox River in Ottawa, IL

I looked closer at the photo to try to determine if it was pin connected. That is when I noticed there are two bridges. One with three truss spans, and a second with one tied-arch span. I presume the truss bridge was for street cars. A tied-arch span would have been way ahead of its time back then.

The UCEB (Ugly Concrete Eyesore Bridge) was built before 1939.
