Lake Park/Plank Road
Lake Park/Kensington
City of Appleton, Wisconsin

The reconstruction of approximately 1,200 feet of Lake Park Road from the Plank Road to Kensington Drive intersection and includes the reconstruction of the Plank Road and Kensington Drive intersections as roundabouts.

The existing intersection of Lake Park Road and Plank Road was a four-way stop with Plank Road intersecting Lake Park Road at approximately 60 degrees. There is a significant amount of utilities located in and around this intersection, which added to the complexity of determining the best location for the roundabout. Three of the legs have single lane entries and exits. The fourth leg has a two-lane entry and a single lane exit.

The existing intersection of Lake Park Road and Kensington Drive was a three-way stop with a right turn bypass from Lake Park northbound onto eastbound Kensington. Adjacent to the intersection is a combination of commercial and residential properties. Lake Park, legs 1 and 2, are single-lane entries and exits. Leg 3, Kensington Drive, is a two-lane entry and a single lane exit.

USH 10 & STH 55 Intersection
Calumet County, Wisconsin

This project is located at the intersection of USH 10 and STH 55 southeast of the City of Appleton in the Town of Harrison, Calumet County. The existing condition required STH 55 traffic to stop for USH 10. Although the intersection had good sight distance in all directions, drivers were still making poor decisions when leaving the stop sign. The intersection had a crash rate of 1.55 with over 80% of the crashes being right-angle crashes and 62% of the crashes resulting in either injuries or fatalities. This project reconstructed the intersection into a roundabout with Highway Safety Improvement Project funding.

The roundabout is a single lane rural roundabout. Because of the high speed approaches, the splitter islands were designed to help reduce the speeds as traffic approaches the intersection. The roundabout was designed to facilitate large farming equipment and oversized trucks.

College Avenue/John Street/
Walter Street Intersection
City of Appleton, Wisconsin

The existing intersection experienced significant traffic delays and had a high amount of crashes. As part of the City of Appleton's reconstruction of College Avenue from Drew Street to Matthias Street, the intersection was redesigned. Both a signalized intersection and a roundabout were evaluated. The roundabout was selected and is a multi-lane roundabout with all three legs having dual lane entrances. The eastbound approach was designed to have a right-turn bypass added in the future.

STH 22 & 54 Bypass
Waupaca, Wisconsin

As part of the STH 22 & 54 bypass project, the connections of the bypass with the existing STH 22/54 on the east side of Waupaca was designed and constructed as a multi-lane roundabout. This roundabout includes design of high-speed approaches, exclusive right turn lane, exclusive left turn lanes and a right turn by-pass lane.
