A brief history of the Chicago & North Western route from Beloit to Winona:


The largest bridge in Beloit, this four span through girder bridge crosses the Rock River.
Built between 1911 and 1912 to replace an aging pony truss bridge, this bridge consists of four heavily built through girder spans.

These spans are set onto the substructures that were once used for the pony truss. It is believed that the former pony truss bridge was recycled and reused in another location.
Overall, the bridge remains in good condition. Currently, it serves as a trail.

The author has ranked this bridge as being locally significant, due to the common design.
The photo above is an overview. The bridge can be accessed from the trail it carries.
