A view of the Navajo Bridge from inside an adjacent stone building, possibly the Old Cliff Dwellers Lodge (Blanche Russell Rock House), that was built circa 1920. Navajo Bridge crosses the Colorado River's Marble Canyon near Lee's Ferry in Arizona. It carries U.S. Route 89A. Spanning Marble Canyon, the bridge carries U.S. Route 89A northbound travelers to southern Utah and to the Arizona Strip, the otherwise inaccessible portion of Arizona north of the Colorado River, which includes the North Rim of Grand Canyon National Park. Prior to the construction of the first Navajo Bridge, the only river crossing from Arizona to Utah was at nearby Lee's Ferry, where the canyon walls are low and getting vehicles onto the water is relatively convenient. The ferry offered only unreliable service, however, as adverse weather and flooding regularly prevented its operation. Construction of the original Navajo Bridge began in 1927, and the bridge opened to traffic in 1929. The steel spandrel bridge design was constructed by the Kansas City Structural Steel Company. The bridge is 834 feet (254 m) in length, with a maximum height of 467 feet (142 m) from the canyon floor. Its roadway offers an 18-foot (5.5 m) surface width with a load capacity of 22.5 tons (although the posted legal weight limit was 40 tons). In 1990, however, it was decided that the traffic flow was too great for the original bridge, and that a new solution was needed. Deciding on a solution was difficult, due to the many local interests. Issues included preservation of sacred Navajo land, endangered plant species in Marble Canyon, and the possibility of construction pollution entering the river. A new steel arch bridge was commissioned by the Arizona Department of Transportation and the Federal Highway Administration, and was completed in September 1995, at a cost of approximately $15 million. The original Navajo Bridge is still open to pedestrian and equestrian use, and an interpretive center has been constructed nearby to showcase the historical nature of the bridge and early crossing of the Colorado River. Bungee jumpers are frequently seen using the span. The original bridge has been designated as a Historic Civil Engineering Landmark. The bridge was placed on the National Register of Historic Places on August 13, 1981.
