SPANNING THE GRAND CANYON

A new Navajo Bridge will replace the present one that crosses the Grand Canyon at Marble Canyon, Arizona. The new bridge is 277 m (909 ft) long with a 221 m (726 ft), braced-spandrel, steel-arch main span that will carry two lanes of traffic 143 m (470 ft) above the Colorado River. The new bridge is being built downstream from the old structure, which will be used as a pedestrian crossing upon completion of the new bridge. This article details the design and construction of the new bridge as well as the historic and political factors involved in this $14 million project.
