John A. Latsch Wagon Bridge
This 12-span open spandrel concrete arch bridge was built in 1916 to connect to the Winona High Bridge and provide a complete route across both channels of the Mississippi River. It crosses the state line.
In 1942 the new Main Channel Bridge was opened (BH 20674, the one that today carries eastbound traffic), along with a new North Channel Bridge, so in 1942 the old High Bridge was torn down to salvage its steel for the war effort. This concrete bridge had little salvage value, so it was spared. However, since the old High Bridge trestle had connected directly to this bridge, that left its west end as a dead end in mid-air.
In 1947 a new concrete ramp was built to connect the west end of the bridge to the ground. This approach span is interesting in its own right, as a set of concrete rigid frame structures.
The bridge was closed due to deterioration in 1996. A local fundraising effort paid for repairs, and it reopened in 2004.
