The San Luis Bridge was constructed in 1911 in San Luis, Colorado, the state’s oldest town. It’s also known as “State Bridge” and “Bridge over Culebra Creek”.
The 57-foot-long (17 meters) bridge is designed with one span of reinforced concrete. The style is an open spandrel arch, a unique design for the Mountain West. In 2007, Costilla County was granted $150,300 to restore the bridge for pedestrian and bicyclist use only, so it no longer operates as a road bridge.
The San Luis Bridge was listed on the National Register of Historic Places on February 4, 1985. The original route was for State Highway 15 in Southern Colorado. It later switched to a county road by the 1980s. Today, it’s accessible off State Highway 159 in San Luis as a pedestrian-only bridge.
