DES MOINES, Iowa — The City of Des Moines is considering replacing two high-crash intersections with mini roundabouts.
The planned changes would affect the Cottage Grove Avenue and Woodland Avenue intersections at 31st Street. This proposal is part of the city's Vision Zero project, which aims to eliminate all traffic deaths and serious injuries by 2040.
According to city officials, these intersections have significant potential for safety improvements. Woodland Avenue ranks 76th and Cottage Grove Avenue ranks 4th statewide for crash reduction potential among similar intersections. Over the past five years, there have been 52 reported crashes at these locations.
Residents have expressed concerns about safety. “When you're trying to leave and come off of Woodland Avenue, you are taking your life in your hand,” said local resident Kay Kopatich.
Pedestrian and cyclist safety has also been raised as an issue. Alex Rice from the Des Moines Street Collective highlighted difficulties due to heavy cross-traffic on 31st Street.
City Traffic Engineer John Davis stated mini roundabouts could reduce speeding and the likelihood of right-angle crashes, potentially saving lives. “They are easy to negotiate,” he added.
During an informational open house attended by about two dozen residents, community feedback was discussed. If approved, the design process will follow. The project is estimated to cost just under $500,000, with funding from the Vision Zero Capital Improvement Program and potential support from the Iowa DOT's Transportation Safety Improvement Program. Construction is expected to begin in spring 2028.
