Racine Street Bridge Roundabouts

Winnebago County

PROJECT PROFILE

Centralized Advancements

A roundabout design in the heart of Menasha boosted efficiency, reduced delays, and ensured smooth operations, even during lift bridge operations.
The Opportunity

In the heart of the City of Menasha, the infrastructure flanking the Menasha Channel posed significant traffic issues. With a lift bridge on Menasha Street and signal-controlled intersections on either side of the channel, traffic congestion was a persistent issue, particularly during bridge operations, and hindered transportation efficiency. Roundabouts emerged as the optimal solution to replace the signal-controlled intersections, promising smoother traffic flow and reduced delays. 

Bridge stretches over river leading to a roundabout in a downtown setting
The Outcome

Traffic efficiency was dramatically improved by replacing signal-controlled intersections with strategically positioned roundabouts. The northern roundabout at Racine Street and Main Street required outside-the-box thinking, as the intersection was surrounded by historic and park property, and the lift bridge was a mere 30 feet south of the northbound entry. The roundabout had to be designed within these physical constraints while minimizing impacts on the surrounding historic properties.   

JT also modified the roundabout design to allow flexibility when the lift bridge is operating and the south leg is closed. A southbound-exclusive lane was added that had minimal impacts on the nearby historic properties. An eastbound right turn lane was also added, allowing vehicles to make a left turn at the roundabout while still allowing cars to queue when the lift bridge is in operation which minimized backups. 

The innovative roundabout design in Menasha has significantly improved traffic flow and reduced delays, even during lift bridge operations, by addressing the unique challenges of the area’s historic and infrastructural constraints.
