Rio Grande Bridge at Radium Springs

Historical marker location:

NM Highway 185, Radium Springs , New Mexico

( 1 mile south of Radium Springs)

This structure – one of the best surviving examples of timber and beam bridge construction in the state – was erected in 1933. The superstructure consists of 19 spans, each 25 feet in length. The roadway is 475 feet long. During the 1920s and 30s, timber beam bridges were an economical and easily maintained solution for crossing arroyos and waterways. Although the bridge no longer carries motorized traffic, it continues to serve pedestrians, bicyclists and equestrians.
