US-14+61 Bridges over Mississippi River at La Crosse, WI

"The 87 foot tall arch for the Cameron Avenue bridge was built in a dry dock downstream and floated into place. This allowed the main channel to remain open for shipping during construction. The Cass Street bridge is being rehabilitated during 2005 and 2006, with all traffic routed on the Cameron Avenue bridge during the project." [John Weeks III]

The approach spans are non-trivial bridge structures in their own right. It looks like curved trapezoidal tub girders were used for the new bridge.

The previous bridge at this location was a low level crossing, consisting of pin-connected through truss spans including a swing span. One of the spans was destroyed in a vehicle collision in 1935.
[I assume the photo is 1881 instead of 1981. Since the high-level truss was not competed until 1939, I wonder if the town had to use a ferry service for four years.]
