OMNNI Roundabouts

College Avenue Roundabout

City of Appleton, Wisconsin


The existing College Avenue/John Street/Walter Street 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 selected alternative was a multi-lane roundabout with all three legs having dual lane entrances, with the eastbound approach designed to have a right-turn bypass added in the future.

Key to the success of this project was the public education on multi-lane roundabouts. OMNNI assisted the city in putting together education information including posters, brochures and presentations.

“The College/John/Walter roundabout has exceeded all expectations of the City of Appleton. Because this was our first dual lane roundabout we were unsure of the success of this new type of intersection within our community.¬†With OMNNI Associate’s design, construction management and public education expertise, the roundabout experience has been a huge success! This roundabout has significantly improved the capacity and safety of this intersection.¬†OMNNI staff went above and beyond in many ways including working with the City and WisDOT staff to develop an educational brochure which we believe played a significant role in the success of this roundabout.”
