Completed in 1926, the Rio Felix Bridge became one of the most important structures in New Mexico’s highway system. It was placed across the river at nearly a 45-degree angle to increase stability during floods. Constructed with three 144 foot Pratt Truss spans, it is the longest bridge of its type in New Mexico. Bypassed in 1984, it is listed in the National Register of Historic Places for its design and for enhancing local farming and tourism at Carlsbad Caverns.
