STH 175 & STH 167 (Holy Hill Rd.)
MTJ Roundabout Engineering provided the roundabout analysis, design, peer review for 30/60/90% plans, and public outreach support to WisDOT, as a sub-consultant to Westbrook Engineering. This challenging roundabout project includes high-speed approaches in a transitional/exurban setting.
Key to this effort was developing a design that was sensitive to ROW impacts replacing an existing two-way stop, while allowing safe residential drives to exist to ensure safety and access for all modes of travel. MTJ played a pivotal role in achieving the correct roundabout design solution and acceptance of this unique roundabout application.
