Abstract: The Michigan Ditch tunnel project is noteworthy because of its unique mix of challenging engineering problems, risk mitigation measures, novel evaluation and design, and innovative delivery method. The project challenges that had to be confronted during design and construction were significant and included a valuable natural resource in the Colorado mountains that had to be protected, an extremely demanding schedule, difficult site access, highly variable weather, and a remote location.
