Mankato, MN — A decade ago, the introduction of roundabouts at two of Mankato’s busiest intersections met with skepticism and dread. The once controversial traffic design is now seeing broad acceptance and even support amidst reflections on their success and local impact over the years. Initially met with predictions of traffic chaos, these roundabouts have instead demonstrated significant safety benefits, with a substantial reduction in severe accidents.
In 2011, state transportation officials proposed installing multi-lane roundabouts at the intersection of Highway 22 and Adams Street, as well as another at the junction with Madison Avenue. This plan initially appeared outlandish to many local residents, including Vance Stuehrenberg, a Blue Earth County commissioner, who likened the concept to “bumper cars” due to the busy nature of the intersections.
Despite widespread apprehension, the Minnesota Department of Transportation (MnDOT) pressed forward with the idea, driven by a desperate need to enhance safety. According to MnDOT’s data, prior to the roundabouts there were multiple fatal and numerous injury-causing accidents at these locations. Scott Thompson, a MnDOT traffic engineer, assured at the time that the decision was rooted in safety, not trend.
The communication strategy employed by MnDOT was robust, involving community outreach that featured interactive demonstrations like a roundabout carpet in their lobby and a tabletop model with toy cars. Despite initial resistance — epitomized by blunt criticisms at community meetings — the narrative began to change once the roundabouts were constructed and operational.
Fast forward to the present, the data validates MnDOT’s decision: since the installation, there have been zero fatal crashes and a clear reduction in severe injuries at these intersections. The figures speak volumes — for example, at the Adams Street junction fatal crashes dropped from two to none, and the total number of injuries fell significantly.
However, the transition wasn’t seamless. Increased minor collisions, primarily sideswipes and fender-benders, occurred due to the learning curve associated with the new traffic pattern. These accidents were often due to failures to yield, underscoring the ongoing need for public education on how to navigate roundabouts properly.
Thompson recounts extensive efforts to familiarize the public with roundabout navigation, including taking his message to various community groups and utilizing media ranging from local TV spots to social media platforms. Educational initiatives even included hands-on learning experiences such as a temporary roundabout setup where locals could practice driving through in golf carts.
Over the years, public sentiment has shifted considerably. Today, many residents appreciate the reduced wait times at intersections and acknowledge the safety improvements. Stuehrenberg himself has turned from a skeptic to a supporter, acknowledging the evident benefits—including potentially life-saving impacts—of the roundabouts.
As the city anticipates the construction of another roundabout, the debate that once raged seems to have calmed. Even those initially opposed or skeptical have observed the benefits these roundabouts have brought to the community in terms of safety and traffic flow.
Reflecting on the journey from resistance to acceptance, MnDOT’s approach—combining data-driven rationale with persistent public engagement—highlights a successful strategy in urban planning and community safety. This transformation in Mankato serves to remind other communities nationwide of the potential benefits of embracing change, even when it initially seems unconventional.
