STH 42 / Interstate 43 & STH 42 / Vanguard Dr.
MTJ Roundabout Engineering’s Mark Johnson, PE, as a subcontractor to the prime site civil firm, provided expert roundabout planning, analysis, feasibility, design, and peer review for this big-box retail development project located in Sheboygan, WI.
MTJ delivered an innovative series of three compact, high-capacity, multi-lane roundabout designs that facilitate business access, a safe pedestrian environment, and effective traffic flow for this existing interchange.
This series of three roundabouts provided the traffic mitigation and access solution for the proposed development for a retail supercenter at this site. The interchange design had to fit within existing ROW to ensure meeting the project development schedule.
Mark Johnson participated in the roundabout educational public involvement component for the presentations to the community, business owners, and elected officials leading to the implementation at this controversial site.
