Crews begin repairs in Glenwood Canyon
GLENWOOD CANYON – The Colorado Department of Transportation began repairs Monday on damage caused by the March 8 rock slide that closed I-70 in Glenwood Canyon for about four days. The cost of the repair project is approximately $860,000. However, the total cost of the rock slide – including CDOT maintenance and design work – is expected to be much higher.Because of the critical need to speed repairs on the interstate, the contract carries with it a $5,000/day incentive for early completion – with $5,000 deducted each day the work runs past their set completion date. Flatiron Construction, in its bid package, set a completion date of May 15; the company can earn a maximum of $31,000 in early-completion incentives by beating this projected date.The repair work is taking place between mile markers 124 and 125, just west of Hanging Lake Tunnel. The work will involve bridge deck and bridge wall repairs (including 150 feet of new steel bridge rail); guardrail repairs (about 120 linear feet) to hillside concrete barrier; median concrete barrier repair (replacement of 400 linear feet); removal and replacement of 690 square feet of concrete retaining walls; straightening of steel bridge girders using a flame straightening process; some lighting and electrical repairs; and repairs to the bike trail below. Finally, the contractor will use approximately 500 tons of base course material on the roadway, as well as 400 tons of patching asphalt to repair the driving surface.Work will be done during the day, Monday through Saturday. There will be a single lane of traffic open in each direction, but motorists may encounter occasional traffic stops, when safety or equipment mobilization warrant. The speed limit is reduced from 50 to 40 mph, and delays should be minimal. While the Glenwood Canyon bike path should open sometime in April, the section between the Shoshone power plant and Hanging Lake rest area will remain closed for safety until the project is completed in May.
