On March 8, 2010, a rockslide caused extensive damage to Interstate 70, punching holes in the road bed and tearing into retaining walls and bridge girders near the Hanging Lake exit, causing a 17-mile stretch of I-70 to be closed to traffic.

Work involved bridge deck and retaining wall repairs that included 150 linear feet of new steel bridge rail; concrete barrier repair that included 400 linear feet of replacement; removed and replacement of 450 square feet of retaining wall; the straightening of steel bridge girders using a flame straightening process; asphalt paving; some lighting and electrical repairs; and repairs to the bike trail below.

Despite adverse weather conditions, Flatiron worked seven days a week and reopened this stretch of I-70 12 days earlier than planned. Flatiron received the maximum allowable early completion bonus for their efforts.
