Mile 4.5 - Navajo Bridge & Marble Canyon Bridge

During the 1990s, a second structure called Marble Canyon Bridge was modeled after the historic Navajo Bridge and built 330 feet downstream from it. This newer bridge accommodates vehicle traffic, while the older one is reserved for foot traffic only. These bridges, with the exception of the Hualapai Skywalk at mile 266, are the most pronounced man-made features in the canyon corridor between Lee’s Ferry and Pearce Ferry.
