This large through truss bridge crosses the Wisconsin & Southern (former Milwaukee Road) tracks and Schilling Road west of Randolph.
Built in 1911, large Quadrangular Through Truss sits on concrete substructures, and is approached by a single deck girder span on the east.
A plaque indicates that the bridge was built by Pennsylvania Steel Company.
The main span is a Quadrangular Through Truss bridge with riveted connections and an A-Frame Portal.
Unlike many other bridges on this line, which were built with expansion points to be able to serve two tracks if ever needed, this bridge does not.
If a conversion to double track would ever have taken place, this bridge would have needed to be completely replaced, as it lacks typical expansion points found on other bridges.
Upon inspection, the bridge appears to be in fair condition, with some deterioration of the substructures noted.
The author has ranked this bridge as being moderately significant, due to the truss design.
The photo above is an overview. The bridge can be accessed from the road it crosses.
