This bridge is part of a total of 4 bridges that make up the La Crosse railroad crossing. The other three bridges, moving east, are the East Channel Rail Bridge, French Slough Rail Bridge, and the Black River Channel Rail Bridge. These bridges were built by the Milwaukee Road, which merged with the Soo Line, which has since been bought out by the Canadian Pacific Railway. La Crosse is one of three places that the Amtrack Empire Builder passenger train crosses the Mississippi River, with the other two being Hastings, MN, and Little Falls, MN.
The upper two photos were taken in September, 2007, while the remaining photos were taken in June, 2007. Notice that the trees on the near side of the river have been cut down, resulting in much better sight lines for photographing this old bridge.
