Skyline Parkway Retaining Wall
Historic Retaining Wall Restored
After the City of Duluth received Federal Transportation Alternatives Program (TAP) funds to rehabilitate the historic bluestone retaining walls that line the Skyline Parkway Corridor, LHB was selected to survey and investigate each site. We determined existing conditions, developed preliminary work scope, coordinated with the MnDOT Cultural Resources Unit and the State Historic Preservation Office, completed detailed plans and specifications for rehabilitation, and performed construction administration services for the City. The Section Three Turnout site, pictured above, was completed in the fall of 2018. This site included a 1,100-foot long dry-stacked stone masonry wall located just below Enger Park. Rehabilitation work at this site included select locations of dry-stack wall reconstruction, concrete cap and guard stone replacement, and pavement restoration on the parkway and turnout.
