Highway 12 Corridor Safety Improvement

About this project

In 2021, MnDOT, in conjunction with Hennepin County, will construct three projects aimed at improving safety and reducing crashes along Hwy 12.

On Hwy 12 from Co. Rd. 6 to Baker Park Rd. in Maple Plain, MnDOT will reconstruct Hwy 12 to install a center concrete barrier. This project will eliminate head-on crashes within this section of Hwy 12.

At Hwy 12 and Co. Rd. 90 in Independence, MnDOT will construct a roundabout. The current intersection has challenging sight lines for entering cars, which contributes to the higher-than-average crash rate. The roundabout will greatly reduce crashes and make it easier for traffic to turn onto and from Co. Rd. 90.

At Hwy 12 and Co. Rd. 92 in Independence, Hennepin County will lead a project in partnership with MnDOT to address the safety issues seen at this location. Currently, the proposed design is under consideration and more details will be available soon.

Summary of work

• Center concrete barrier on Hwy 12 between Co. Rd. 6 and Baker Park Rd.
• Roundabout at Hwy 12 and Co. Rd. 90
• Improved intersection at Hwy 12 and Co. Rd. 92
• Reduced crashes and improved safety within corridor

Traffic impacts

Future

Hwy 12 will be closed at the locations of the three projects. A single detour will bring traffic around the projects. Local residents will maintain access to Hwy 12 where needed. Hwy 12 will be closed to through traffic, a detour will be provided. Details of the proposed detour will be made available soon.
