The 1993 Outstanding Civil Engineering Achievement Award goes to the $490 million I-70 Glenwood Canyon in Colorado. The final link in Interstate 70 from Baltimore, Md. to Cove Fort, Utah, it opened to traffic October 14, 1992. Packed into Glenwood Canyon's 12.5 miles are 39 bridges and viaducts; the first U.S. highway tunnels to use rock reinforcement for permanent support, which also feature state-of-the-art incident detection and management facilities; a retaining wall system that squeezed four lanes of traffic into a space that had barely fit two previously; and numerous other technical innovations. Also included was a traffic management system that kept up to 18,000 vehicles per day moving at the peak of construction without a single traffic fatality or serious injury. Perhaps most significant, the project involved an unprecedented degree of cooperation between the project team and environmentalists and recreationalists to create a major highway that preserved and even enhanced one of the nation's premier natural settings.
