View an article regarding the construction of this route.
Located on the west side of Mosby, this steel stringer bridge crosses the westbound/southbound lanes of US Highway 69.
Built in 1954 when the road was expanded, the bridge consists of a single steel stringer span, set onto concrete substructures. The design consists of six parallel beams per track, with a ballasted deck.
This style of bridge was commonly used for grade separations during the 1940s and 1950s, due to the ease of construction and little maintenance required. Although 69 was upgraded here in 1954, I-35 would open to the west approximately 10 years later.
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 good condition, with no significant deterioration noted.
The author has ranked this bridge as being minimally significant, due to the common design and newer age.
