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


This small I-Beam bridge crosses Troy Drive on the north side of Madison.
Originally built in 1896 as a dual track deck girder, that bridge would later be replaced with the current I-Beam span.
Significant work was done between 1960 and 1966 through this area. Part of this could have been the replacement of the older girder span with the current span. The bridge continues to rest on the 1896 stone abutments.
Overall, the bridge appears to be in good condition.

The author has ranked this bridge as being minimally significant, due to the common design.
