This massive warren pony truss bridge was originally constructed near Las Animas, Colorado to carry the Las Animas branch across the Arkansas River.
The bridge was moved here in 1940 as part of the construction of the Sunflower Army Ammunition Plant. Originally, the road underneath was K-10; which has since been relocated to a freeway bypass nearby.
It is one of the few examples of a railroad crossing solely over a highway using a truss span.
The truss is a 6-panel riveted Warren Pony Truss. It was built in 1907 by the Wisconsin Bridge & Iron Company. It was likely moved and re-erected by American Bridge Company.
The substructures of the bridge are typical concrete spans.
Overall, the bridge remains in good condition. The bridge appears to see occasional maintenance. There is no sign of much deterioration.
The author has ranked the bridge as being moderately significant due to the design and the relocation history. The ammunition plant was decommissioned in the late 1990s.
Since being decommissioned, the track only serves a couple of spurs.
