Located between Logan and Woodbine, this large girder bridge has changed significantly since the original construction
First built in 1899 to cross the Chicago & North Western, the bridge originally consisted of a large Pratt Through Truss, approached by two deck girder spans on the north end. The north approach was rebuilt with the current spans in 1948, and a through girder span replaced the truss between 1973 and 1982.
The bridge runs at a significant skew. In addition, the substructures on the bridge are a combination of stone and concrete.
In addition to crossing present day Union Pacific, the girder spans also cross Perry Trail. The southern girder span features a fishbelly end to align with the through girder span.
Overall, the bridge appears to be in good condition, with no significant deterioration noted.

The author has ranked the bridge as being locally significant, due to the common design and newer age. Unfortunately, the deck girders are the only historic component remaining on this bridge.
