The scope of the project included milling and removal of a road and bridge constructed in the 1920s, installation of a new road and bridge to divert traffic from the pristine Gibbon River, paving a major complex parking area with three pedestrian viewing areas, restoration of extensive vegetation in sensitive environmental areas, positioning boulders and landscape logs in picnic areas and placement of bio-degradable wattles for erosion control. HK Contractors completed highly skilled excavation with cuts as high as 124 feet to allow for accessible parking areas and trails. Work was completed within wetlands, geothermal areas, thermal seeps and thermal cores. The work schedule anticipated 25,000 vehicles per week travelling through the construction zone in the high tourist summer season.
