Kaibab Suspension Bridge
The Kaibab Trail Suspension Bridge (a.k.a. the Black Suspension Bridge) extends across the Colorado River in the inner canyon of Grand Canyon National Park with a span length of 440 feet. The bridge is part of the South Kaibab Trail used by mules going to Phantom Ranch. Before 1907 the only way to cross the river was by boat. Black Bridge was built in 1928 and designed by Ward Webber and constructed by John Lawrence. It remained the only river crossing for hundreds of river miles until the Silver Bridge's construction downstream.
