Duben Avenue Upgrades

Location: Anchorage, AK

These improvements included an upgraded road section, new sidewalks, storm drainage, lighting, and signal modifications for this one-mile-long roadway. Duben “West” had steep grades over 10% and a narrow right-of-way, making it necessary to construct large retaining walls to limit the impacts of roadway improvements. As the Engineer of Record, CRW provided construction administration and special inspection during the retaining wall installations.
