county highway reconstruction

Kenosha County, in partnership with the Wisconsin Department of Transportation (WisDOT), embarked on a 3.5-mile-long reconstruction to expand County Trunk Highway S from two lanes to a four-lane highway – the largest roadway project in the County to date. This new highway is a critical access point into Kenosha, is better equipped to handle the increasing traffic load, and now meets Wisconsin state highway safety standards.

Benesch led the construction management for this project, which included a new three-span precast girder bridge over the Canadian Pacific Railway, a new slab span bridge over the Kilbourn ditch, an extension of a box culvert over the S. Pike River, and a new at-grade Union Pacific Railroad crossing.

Other elements included staged construction, traffic control and detours to facilitate the addition of two new WB lanes of traffic, reconstruction of the existing lanes, an eight-foot-wide multi-use path, improved alignment with side street intersections, and installation of guardrails to improve traffic safety.

The project involved three new signalized intersections, including replacing two existing ones and adding a new one at a commercial development. A new stormwater detention pond also alleviated flooding issues caused by heavy rain events. Utility coordination and relocation were also especially critical.

The project included more than 350,000 cubic yards of common excavated materials, 220,000 tons of base aggregate, 200,000 tons of breaker run and 88,000 tons of asphalt pavement.
