Constructing a four-lane dual highway through the 12 miles of Colorado's Glenwood Canyon involves several engineering innovations: cantilevered roadways, unusual retaining walls and grouting that permitted spread footings instead of more expensive alternates, a comprehensive traffic control program managed by the consulting engineer, and 39 bridges designed to be bid as precast, poured concrete or steel. Because of the fragile ecology of the canyon walls, contractor sites are severely restricted. Construction began in 1981 and is scheduled for a 1993 completion.
