Navajo Bridge, Marble Canyon, ArizonaThe original Navajo Bridge, on the right, was built in 1929 at a cost of $390,000 to provide a more reliable crossing of the Colorado River than Lees Ferry, which was often unavailable due to weather or other considerations. Apart from the bridge at Page, it is the only crossing of the river for over 600 miles. By 1990 the old bridge had become obsolete, and needed to be replaced. The new bridge, built in 1994 at a cost of $14,700,000 was designed to compliment the original structure, which is still in place for use by pedestrians and horses. The bridge spans the Colorado River and Marble Canyon north from Navajo Nation Reserve, and is the main route for tourists who wish to visit the North Rim of the Grand Canyon.
