Overview
Denali State Park Byers Lake Outlet Bridge suffered a structural failure in 2020 due to deterioration of the existing girders. Several of the existing gabion basket supports have shifted off center and provide minimal seismic restraint. Existing railing construction and deck slopes are a potential risk to public safety. Ak-JAKE provided the Alaska Department of Natural Resources with 4 design alternatives. The chosen alternative was was evaluated to 35% design.
The project is located approximately 147 miles north of Anchorage and 97 miles from Denali National Park Service Entrance.
