It should be noted that the bascule span was originally from a concrete arch bridge built in 1909 and collapsed in the same year; that's the reason why the bascule span wasn't aligned with the through truss.
This was a really cool old bridge, very narrow and long. This pic was taken in the early 1980's on the East Peoria side of the river.
