A brief history of the Chicago & North Western route to St. Louis:


Located near I-80 and IL-40, this large through truss bridge crosses the Hennepin Canal and the Hennepin Canal Parkway, near Buda.
Built in 1905, the bridge consists of a large Quadrangular Through Truss with riveted connections. The bridge is set onto stone abutments, repaired with concrete. The truss also contains a heavy M-frame portal bracing, typical of 20th Century Quadrangular trusses.
The Quadrangular design is rather rare on a national scale, although is actually rather common along the Chicago & North Western. The design was popular due to the resilience demonstrated in the event of damage.
Overall, the bridge appears to be in good condition. As a secondary mainline, the bridge is in better condition than trusses closer to Peoria.

The author has ranked the bridge as being moderately significant, due to the truss design.
