Sliding surface soils had resulted in reducing the width of a private access road in western Colorado. In order to restore it both to its original width and to improve safety and access, Hayward Baker designed and built a shoring system. Working at an elevation of 7,500 ft, the company installed 2,200 linear ft of 20-ft high wall consisting of soldier piles and lagging in the most unstable sloughing-prone section along the road. The project included a total of 350 soldier piles, 175 200-kip ground anchors and 44,000 sq ft of permanent wood lagging. The road was cleared and opened to traffic nightly during construction. The project was completed in approximately four months during one of the worst Colorado winters in the past 25 years when snow was 3 ft deep a majority of the time. Once completed, the work resulted in a 10-ft to 13-ft wider road than before construction began.
