This project involves replacing a deficient six-barrel culvert on the Holzwarth Access Road with a new steel girder bridge and cast-in-place concrete deck, located in Rocky Mountain National Park about nine miles north of Grand Lake, CO, at an elevation of 8,900 feet. Work includes removal of the existing culvert, new abutments and micropiles, temporary stream diversion, riprap, roadway surfacing, relocation of an electrical line, and relocation of historic head gates. Site access is restricted via a narrow 13-foot road with tight turns, requiring temporary widening and a truck turnaround, with no construction access allowed more than 100 feet west of the bridge. The anticipated schedule runs from advertisement in September 2026, award in December 2026, to contract completion in November 2027. The total estimated cost is between $700,000 and $2,000,000.
