1950s 11th Street Bridge over Cedar River in Waterloo, IA

(Satellite)

Judging by the flood wall on the far right, this river has some significant floods.

I normally don't note UCEB (Ugly Concrete Eyesore Bridges), but I normally don't come across a construction photo. At least these steel girders have some character with the bottom chord curve.
