Notes
  • Significance: Crooked River High Bridge was completed in 1926 as part of the Dalles-California Highway (U.S. 97). It was designed by State Bridge Engineer Conde B. McCullough. The bridge is a single-span steel deck arch that is 464' long and 27' wide. The main span is 330' long and consists of a double-hinged braced spandrel deck arch. Hinge pins were provided at both crown and skewbacks. The structure was designed to act under dead load as a three-hinged arch and under live load as an arch with skewback hinges only. There are 134 feet of reinforced concrete approach spans. The railing is constructed of precast concrete arches, with a cast in place cap. The structure was one of the highest bridges in the United States, at 295' from deck to streambed, when it was constructed. A high line cableway was used in the erection of the structure, rather than a traveling derrick or hoist.
