Show 1931 Projects completed during this period were: Deadwood Dam - Utah's early years of dam building activities culminated in the mile-high Deadwood Dam built only by combining and using the stern lessons already learned with new methods and machinery. Had it not been for experience gained in construction organization and methods developed at Deadwood, the building of future giants Hoover, Bonneville, and Grand Coulee--might have been delayed many years. The first bulldozer, diesel trucks, and gasoline-powered shovels solved the access and construction problems of the job -- where railroads could not be built, and where everything had to be hauled 67 narrow, mountainous miles from Cascade over three summits 6,800 feet to 7,400 feet high. The site was accessible only six months of the year, and to get an early start in the spring the concrete-mixing plant and two-inch cableways, enormous for the times, were hauled to the dam site by sleigh through snow 16 to 35 feet deep in the mountain heights. Concrete pouring from an overhead cable started early in the spring of 1930, foundation stripping having been done the previous year, and finished in the falling snow of November. Snow was nine feet deep in the passes and when the only tractor broke down, the last group of men coming out had to walk the 67 miles to Cascade. Deadwood Dam was the second joint dam-building venture of Morrison- Knudsen Co., Inc. and Utah. This concrete gravity-arch storage dam is located in central Idaho on the Deadwood River and is an irrigation and power unit of the Boise Project. The approximate cost of this project was $4,928,000. Railroad Grading in Utah for Bingham and Garfield Railway in the amount of $3,987,000. Hoover Dam Railway in Nevada for the U. S. Bureau of Reclamation in the amount of $520,000. Keddie-Bieber Railway cutoff in California for Western Pacific Railroad Company in the amount of $5,000,000. Eight cutoff tunnels on the Keddie-Bieber line in California for the Western Pacific Railroad Company. The cost of this was included in the project above. Salina-Emery Highway in Utah for the U. S. Bureau of Public Roads in the amount of $44,000. Nephi Highway in Utah for the Utah Road Commission in the amount of $66, 000. |
