Located on the north of Mosby, this deck girder bridge crosses 144th Street at Cameron Road.
Built in 1931 during a line realignment, the bridge consists of a single deck plate girder span, set onto concrete substructures and featuring a ballasted deck. The design follows a pattern more commonly seen built between 1900 and 1905, possibly indicating that this bridge is older and from another location.
The Rock Island sometimes reused spans during realignments such as this. The author is currently doing more research into if there is further history of this bridge.
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 good condition, with no significant deterioration noted.

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