Columbia CTH V Reconstruction

« Return to Project Search

Columbia County hired Ayres Associates to design the reconstruction of approximately 4 miles of CTH V from STH 113 to CTH J. The westerly 2-mile segment of the project passes through a highly developed residential area serving many private residences along the shorelines of Lake Wisconsin. The roadway in this area is to be reconstructed as an urban roadway and currently has a substandard roadway section and vertical and horizontal alignments.

The preliminary design and plans were prepared for a new bridge carrying CTH V over Lake Wisconsin. Navigational clearance improvements and staged construction were key considerations. Final plans were prepared for three locations along the project requiring culvert structures. The structures involved two- and three-cell corrugated steel arch pipes with cast-in-place concrete headwalls.

Because of a lack of construction funding, the County decided to place a majority of the westerly portion of the project on hold indefinitely, stopping the design before a 60% plan submittal. However, final plans and specifications were prepared for the reconditioning of the easterly 2 miles of the project, which includes replacing the pavement and making geometric improvements to smooth out curves and hills. This section was constructed in 2015.

In addition, Columbia County plans to use recently secured STP funding to reconstruct a portion of CTH V from STH 113 to the structure spanning the Okee Bay/Spring Creek Inlet. Final plans are being prepared for this additional work.
