Located in Rocky Mountain National Park, approximately nine miles north of Grand Lake, CO, along US HWY 34 at an elevation of 8,900 feet, the culvert conveys flow from the Colorado River and provides access to the Holzwarth Historic Site. The purpose of this project is to prevent future roadway damage and flooding while maintaining access to employee housing, the historic site, and National Park Service and Forest Service recreation opportunities. SCOPE OF THE WORK:    The project will consist of removal of the existing six barrel culvert and construction of a new steel girder bridge with a cast in place concrete deck. New bridge abutments and micropiles. Temporary stream diversion and riprap. New aggregate roadway surfacing. Relocation of an existing electrical line. Relocation of existing historic head gates into a new concrete slab. Access to the site is through a gate at the south end of the Holzwarth Historic Site Parking Lot and along the Holzwarth Culvert Access Road. The Holzwarth Culvert Access Road is approximately 13’ wide with tight turns. Temporary widening will be necessary to prevent truck off tracking on to sensitive environmental resources. A temporary truck turnaround will also be necessary as no construction access is allowed more than 100’ west of the bridge.
