Near the end of 2019, Dakota County began working with the cities of Apple Valley and Rosemount to address traffic and safety issues at the intersection of County Road 33 (Diamond Path) and 140th Street/Connemara Trail. Based on the traffic volumes and turns observed, we are considering the reconstruction of the intersection into a roundabout.
The county has evaluated needs and options for this 4-way-stop intersection periodically since 2008. Traffic volumes and anticipated growth are now causing increased concerns about safety and delays. The first step was a feasibility study, which looked closely at problems with maintaining the four-way stop and future design alternatives.
Our analysis and recent experience have confirmed that a roundabout should be a good long-term solution for this intersection. The feasibility study also addressed other issues along approach roadways. For example, we’ve heard many comments about the need for possible roadway improvements north of the intersection – including the addition of possible multi-use trails (design and construction to be addressed separately from the proposed roundabout).
Tentative project timeline
- 2020: Feasibility study and preliminary engineering design
- 2021: Final engineering design, including right-of-way and utility details
- 2022: Construction
Opportunities for public input
Dakota County and the cities are regularly providing project information. We welcome your input, even as public health guidance precludes an in-person public meeting. To stay informed and involved, please review the information below.
