C&NW built its first bridge here in 1871; the swing span collapsed under load when a bridgetender failed to align the tracks properly upon closing it. It was promptly rebuilt. The swing span was replaced in 1899. The entire bridge was reconstructed by C&NW in 1928, replacing the through-truss approach spans with plate girder spans. It was abandoned and mostly demolished in 1977.

It also included an approach bridge over the North Channel, which actually crossed the state line. This North Channel bridge is still intact except for one span that has been removed.
