BACKGROUND
Dakota County Project Manager Doug Abere will be attending the work session to discuss two county
projects and provide updates. The discussions will include the Diamond Path/Connemara Trail
Roundabout Feasibility Study and the Highway 42 Visioning Study.
Diamond Path/Connemara Trail Roundabout Feasibility Study
Near the end of 2019, Dakota County began working with the cities of Rosemount and Apple Valley 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, the County is considering the
reconstruction of the intersection into a roundabout. The current feasibility study will look closely at
problems with maintaining the four-way stop and future design alternatives. This work will also consider
the potential for multi-use trails extending north of the intersection. The team has scheduled a public open
house meeting for Thursday, February 6, 4:30–6:30 p.m. at the Rosemount Community Center. The
timeline for future work anticipates final engineering design in 2021 and construction in 2022.
Highway 42 Visioning Study – Starting Soon
The County Highway 42 Visioning Study is a long-term 15-mile Corridor Study, from the County’s west
border in Burnsville, through Apple Valley, to US Highway 52 in Rosemount (15 miles). Highway 42 is a
principal arterial in the region’s highway system managed to balance efficient travel with limited access.
The Study will update a similar plan completed in 1999 to incorporate changes to the corridor since that
time, and to consider current traffic and land uses based on 2040 Comprehensive Plans. The work will
provide a framework to guide future improvements along the corridor. Dakota County is the lead agency
for the Study, with participation from the Cities of Rosemount, Apple Valley, and Burnsville. The Highway
42 Study is ready to begin at the end of January 2020 and will take up to 18 months to complete.
RECOMMENDATION
Dakota County will attend the meeting to update and answer questions regarding these two projects.
