Bridge Documentation

This bridge is noted for its unique design of rolled beams used on the vertical members. They do not conform to any common steel shapes rolled at steel mills today. These verticals also have patent dates stamped on them. The referenced patent however is more focused on the bridge connection details rather than the unique rolled beams used on this bridge. 

John Marvig provided some additional information on this bridge which answered some of the questions this bridge initially presented. His information follows: Bridge was assembled from three different bridges. The 232'6" Whipple Truss was brought in from the East Channel Bridge over the Mississippi River, at La Crosse, Wisconsin. Originally built 1876, the span was cut down 247' in 1903 when it was relocated, and strengthened in 1941 by additional bracing on the upper angle connections and end panels. The other two spans, a pair of 146'3" Pratt Through Trusses were relocated from side by side bridges. One came from the East Channel Bridge in La Crosse, and the other came from the French Slough Bridge, also in La Crosse. Both were built in 1876 as 160' Spans, and cut down in 1903. Strengthened in 1941 when additional bracing was added to the upper connection. The floorbeams came from the original Shortline Bridge across the Mississippi River in 1903, and were originally built 1880. American Bridge Works of Chicago, Illinois built the La Crosse spans. Information comes from the Milwaukee Road Archives at the Milwaukee Central Library

This bridge has a main span that is a rare example of a pin-connected Whipple railroad truss. Many such bridges once existed, but most were replaced by the early decades of the 20th Century with heavier railroad bridges. This bridge was abandoned around 1981 and is today converted for pedestrian use. In addition to the Whipple truss span, the bridge also has three stylistically similar Pratt truss spans. The substructure is concrete and has a 1903 date cast into it. However, the truss spans, by design, appear to be much older, perhaps from the 1880s.
