Located on the west side of Mosby, this deck girder bridge crosses the eastbound/northbound lanes of US Highway 69.
Built in 1931 during a line realignment, the bridge consists of a single deck plate girder span, set onto concrete substructures. The girder has markings indicating it was built by American Bridge Company, although the design follows a pattern more commonly seen built between 1900 and 1905. It is possible this span was moved here from another location and is older than 1931.
In addition, a second track can be seen built into the abutments. It is unknown if there ever was a second track, and if there was, when it was removed. The bridge also runs at a skew.
During 1930 and 1931, the Rock Island built a new alignment between Mosby and Lawson. As a joint agreement, the Milwaukee Road rebuilt their route through Mosby and the two shared operations of a single mainline. This bridge sits on a segment where the two mainlines split. Union Pacific maintains this as main track 1.
Overall, the bridge appears to be in fair to poor condition, with significant cracking noted on the north abutment. However, the southwest wing wall has been rebuilt with prefabricated concrete panels. The author will continue to research if this bridge is actually older than 1931.
The author has ranked this bridge as being locally significant, due to the common design.
