  • Very long, very high footbridge spanning the canyon. Originally built for bridge workers building the Glen Canyon Bridge (the large deck arch next to the dam). Survived at least until 1959.
  • From a Roebling ad in the July 1958 issue of Civil Engineering: "The bridge was completed in sixty days and features a steel mesh deck, to reduce wind resistance. Construction was started by lowering two 5/8 in. cables to the bottom of the west side of the gorge, transporting them across the river by boat and raising them on the east side by block and tackle. The six main suspension cables are 1 3/4 in. diameter prestretched galvanized bridge strands. From them are hung sixty-four 5/8 in. suspenders, attached to 7 ft-wide floor beams. The wire mesh floor is laid on eight 1 in. diameter deck cables. These in turn are supported every twenty feet by the floor beams. For safety, four handrail cables are attached to the suspenders. To add stability in strong winds, two 1 3/4 in. bridge strand wind brace cables run below the deck on either side for its length."
