The spectacular Navajo Bridge spans the Colorado River at Marble Canyon along Hwy 89A, about 14 miles past the Hwy 89/89A fork. Actually, there are two bridges: a modern one for motorists that opened in 1995, and a historical one from 1929. The Navajo Bridge Interpretive Center on the west bank has good background information. Look up – California condors are often spotted overhead – and look down, too, to possibly catch a view of rafting groups who've recently left nearby Lees Ferry on the start of a river journey through the Grand Canyon.
