The Río Grande Gorge Bridge will be down to just one lane until Dec. 15 so the state transportation department can repair damaged guard rails.
Crews are cutting out damaged rails and poles, welding in new lengths of metal and repainting the repaired areas.
Traffic is being regulated at either end of the bridge.
The estimated cost of the repairs are about $40,800, according to Rosanne Rodríguez, a district spokesperson for the New Mexico Department of Transportation.
Rodríguez said the project and traffic restrictions are estimated to last through Dec. 15.
