Located on the west side of Mosby, this large deck girder bridge crosses 122nd Street just east of US-69.
Built in 1931 during a line realignment, the bridge consists of a single deck plate girder span, set onto concrete substructures. While the original approach was likely a trestle, two new steel stringer spans were added on each end in 1948.
Because the bridge runs at a heavy skew, the bridge has a distinct look. The approach spans are unusual, as they feature only two beams, similar to a deck girder.
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. To the east of this location, the railroads used a split mainline.
This bridge is also considered to be a DM&E bridge instead of Union Pacific, as DM&E does the maintenance on this segment of track.
Overall, the bridge appears to be in good condition, with no major deterioration noted.
The author has ranked this bridge as being locally significant, due to the common designs.
