Roundabout Design

The Wisconsin Department of Transportation is replacing the Racine Street movable bridge over the Fox River in Menasha. To reduce the overall cost of the project roundabouts are being proposed at the adjacent intersections which allows for the bridge to be reduced from three lanes to two lanes. JT Engineering (JT) was retained to review the roundabout analysis and review/optimize the preliminary horizontal geometrics at the intersections on Racine Street at Main Street and at Ahnaip Street/Keyes Street.

JT optimized the roundabout designs to fit within the bridge controlled alignment while minimizing right-of-way impacts without compromising the roundabouts capacity, safety (performance checks) and truck accommodations.
