The Rio Grande Bridge at Radium Springs is a historic timber beam bridge built in 1933. As of 1997, it still carried NM 185 over the Rio Grande, about 1miles south of Radium Springs, New Mexico. It was listed on the National Register of Historic Places in 1997.
In Google Streetview imagery captured May 2018, and in Google satellite view, the bridge is unused except by pedestrians, and is seen immediately adjacent to a modern replacement bridge.[1]
It was described by David Kammer in its 1997 NRHP nomination as a 19-span timber beam bridge, crossing the "Rio Grande as it flows in a now well-defined channel some forty miles below Elephant Butte andCaballo Dams. / The substructure consists of 18 creosote-treated timberpiers, or bents, each containing seven piles stiffened withdiagonal timbers, or sways. The bents measure approximately 12feet from the waterway to the deck. Timber abutments, protectedby steel bulkheads, are located beneath each of the approaches.The superstructure consists of 19 spans, each measuring 25 feetin length. The deck, consisting of a 2" x 4" timbers with anasphalt surface, rests on steel stringers. The roadway is 475feet long and 29 feet wide and is flanked by timber felloes. Thebridge's timber rails are lined with metal guardrails."[2]
