The City of Milwaukee and Wisconsin Department of Transportation (WisDOT) are planning to install four mini roundabouts on N. 51st Street/Boulevard at W. Hadley Street, W. Locust Street, W. Chambers Street, and W. Keefe Avenue. The traffic signals or stop signs currently at these intersections would be removed.

The intersections were selected for the following reasons:

• All four intersections experienced a high frequency and severity of crashes.
• These crashes included disregard of red/stop sign, rear-end, and left turn crashes resulting in right-angle crashes.
• There is a large number of pedestrians using and crossing the corridor due to schools near W. Locust Street, W. Chambers Street, and W. Keefe Avenue, as well as St. Joseph's Regional Medical Center at W. Chambers Street.
• The section of W. Locust Street at N. 51st Street and N. 51st Boulevard at W. Keefe Avenue are on the City of Milwaukee's pedestrian high injury network.

• Reduce crashes at the intersections
• Calm traffic throughout the corridor
• Increase safety for all users, especially people walking and biking

Mini-roundabouts, like other roundabouts seen in more suburban contexts, are one-way circular intersections where vehicles move counterclockwise around a central island. There are no traffic signals or stop signs so vehicles can flow continuously through the intersection.

Vehicles entering a mini-roundabout slow down and yield to the vehicles already within the circle.

The islands within a mini-roundabout are paved and designed to allow for larger vehicles to drive over them when extra space is needed.

The central islands in a mini-roundabout are bigger than the central islands in a traffic circle. The City of Milwaukee has several traffic circles installed throughout the City, including on Bartlett Avenue, Maryland Avenue and Washington Street. These streets have a lower volume of traffic than 51st Street.

The project is funded through the WisDOT Highway Safety Improvement Program (HSIP) and includes 90% Federal Funding, and 10% City funding.
