Navajo Bridge, Spanning Colorado River at U.S. Highway 89 Alternate, Page, Coconino County, AZ

Significance: As the only crossing of the Colorado River for some 600 miles, the Navajo Bridge has had a profound impact on the commerce and transportation of a rugged, remote and isolated part of Arizona. Its construction opened the state from the north, providing a valuable tourist route to Grand Canyon National Park and the rest of the state. The Navajo Bridge marked an important milestone of engineering design, logistical planning and construction supervision. It was the first steel deck arch built in Arizona and a nationally prominent example of this uncommon structural type. An extraordinarily dramatic span high over the Grand Canyon, it is Arizona's most aesthetically and functionally successful example of civil engineering.
