Davis Dam-Kingman 69 kV Transmission LineGeolocation: 35.2143, -113.7633

Western Area Power Administration (Western) reconstructed the 69-kV Davis Dam to Kingman TAP transmission line. The new line, constructed with a combination of steel and concrete structures, will replace an existing wood supported line that was constructed in 1947. The new transmission line is approximately 27.3 miles in length and extends from the substation at Davis Dam located on the Colorado River on the west end, through Golden Valley, and terminates at the Mohave Electric Corporation's Kingman, Arizona TAP. Terracon overcame significant challenges to complete the geotechnical exploration of the site. Boring locations were chosen on the basis of project requirements and in concert with sensitive environmental and cultural resource issues along the alignment. Special rig access considerations were also required in the Lake Mead National Recreation Area on the west end of the project alignment.
