Contractor hired for I-70 tunnel repair

Pete FowlerGarfield County correspondent

GLENWOOD SPRINGS The Colorado Department of Transportation has hired a contractor to repair the crack in the eastbound bore of the Hanging Lake Tunnel.”CDOT has undergone its emergency contracting procedure to hire Concrete Works of Colorado,” CDOT spokesperson Nancy Shanks said. The company worked on the Grand Avenue Paving Project in Glenwood Springs and is contracted for an upcoming Interstate 70 paving project, she added.Interstate 70 traffic in Glenwood Canyon is being diverted through the westbound tunnel, which has one lane open in each direction. Shanks said she was not aware of any traffic delays or problems associated with the diversion.Shanks said CDOT officials met Tuesday to discuss the scope of the repair work that needs to be done, and that equipment has been mobilized in preparation for fixing the crack. No specific information from the meeting was available.”They’ll learn a lot more after they map out the scope of work,” she said.CDOT announced Friday that engineers found a crack that widened to the point where it was no longer safe to drive through the eastbound bore. Engineers had been monitoring the crack, and an inspection showed it had recently expanded. The crack is above the eastbound lanes/bore in the five-story command center building.The 4,000-foot-long tunnels, completed in 1992, run between two rock outcrops. The command center was backfilled during construction, and over the years rockfall and debris have added excessive weight. The increasing weight opened a crack that is estimated to be more than 70 feet long.The cost of the project, method and length of time required for repairs were unavailable Tuesday afternoon.
