The Salt River Canyon Bridge is on an s-curve alignment at the bottom of a steep canyon and matches the existing bridge which was converted to a pedestrian bridge; the new bridge was intended to contrast the old bridge by showing a modern streamline example of the traditional arch form; the red color was selected for the bridge to signify contemporary features and to complement the reds and browns of the canyon walls; the Indian art forms on the bridgerail and adjoining rest area structures were designed by the two Apache Indian Tribes residing on either end of the bridge. The bridge has an overall length of 380 feet and a main span of 186 feet
