Information about upcoming traffic impacts will be posted as details become available. 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.
About this project
In 2021 and 2022, 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. MnDOT will construct this project in 2021.
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 severe crashes and make it easier for traffic to turn onto and from Co. Rd. 90. MnDOT will construct this project in 2021. The improvements include:
A reconfigured Co. Rd. 90 to better connect the lanes north and south of Hwy 12
Access for walkers and bicyclists crossing Hwy 12
Drainage ponds to protect the environment
Improved sightlines for motorists entering Hwy 12
15-foot-wide raised concrete median
Westbound roundabout designed to accommodate expansion
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. The project will realign Co. Rd. 92 with a bridge over Hwy 12 and the railroad tracks and construct a roundabout on Hwy 12 for traffic entering and exiting Hwy 12 from Co. Rd 92. Hennepin County will construct this project starting in 2021 and continuing into 2022.
