Built in 1899, the curved trestle has an overall length of 323 feet and rises 52 feet above the canyon floor. Vertical supports spaced 15 feet apart consist of 12" x 12" timbers. The rails (removed in 1948) and crossties were placed on 8"x16" stringers held together with three-quarter-inch bolts and cast iron spacers.
