Bridge rehabilitation activities included the heat straightening of bent steel members damaged over the years by automobiles and large farm vehicles; pipe rail and sway bracing repairs; installation of new approach guard railing; concrete repairs and wing wall modifications; and reinforcement of bridge piers in accordance with United States Department of the Interior and Arizona State Historic Preservation Office guidelines. The repaving of the roadway approaches at each end of the bridge and the construction of an interpretive plaza provide for enhanced public access and enjoyment of this historic structure.
