County Road 92 safety improvements

At Highway 12 in Independence

Hennepin County, in coordination with Minnesota Department of Transportation (MnDOT) and the City of Independence, is making safety improvements at two locations where County Road 92 intersects with Highway 12. This project is part of several planned improvements on Highway 12 in Independence, Maple Plain and Orono. For more information, visit MnDOT's Highway 12 Corridor Safety Improvement page.

Construction began in September 2021.

Project timeline showing planning and design phase complete. Construction is expected to begin in 2021. Major construction activities will be complete in 2022 and the entire project be complete in 2023.
 
Open all

Highway 12 segment closed

On Monday, April 18, we closed Highway 12 between County Road 90 and the south leg of County Road 92. The north leg of County Road 92 will remain closed. Both closures will be in place until fall.

There will be a significant amount of work happening in this area.

Getting around the closures

Highway 12 remains closed to through traffic between County Road 90 and the south leg of County Road 92. The north leg of County Road 92, which we closed last year, also remains closed. Please continue to use the signed detour as listed below.  

For people driving on Highway 12

  • Watertown Road (County Road 6)
  • South leg of County Road 92

For people driving on County Road 92

  • Watertown Road
  • County Road 90
  • County Road 11

Using the signed detour will keep you from experiencing additional delays and getting frustrated. It will also help local streets stay safe for the individuals and families who live and work in the area.

Temporary traffic signals on Watertown Road

Due to these traffic shifts, you will encounter temporary traffic signals at the intersections of Watertown Road and County roads 92, 90, 83 and 19. These traffic signals will remain in place until Highway 12 and County Road 92 reopen to traffic in the fall.

Maintaining local access

We will maintain access for people who live within the immediate construction area and emergency services during construction. This will be an active construction site, so there may be times when access is tightly controlled and driving surfaces may be uneven.

In addition, we will keep Highway 12 open between County Road 90 and Watertown Road (County Road 6) so people can continue to visit local businesses and destinations around Maple Plain and Independence.

If you are traveling around the area, please remember to allow yourself extra time to get to your destination, check signs regarding local access and drive safely around crews.

New County Road 92 bridge foundation and supporting structures complete  

Project crews recently finished constructing the new County Road 92 bridge supporting structures, including abutments, piers and beams.  

With this work complete, crews can begin constructing the new bridge deck. The bridge deck construction will be a lengthy process that includes:

  • forming and pouring the new bridge deck and approaches, 
  • constructing new concrete bridge railings, and
  • paving the new roadway connecting the bridge to the realigned County Road 92 

Completing all this work and allowing the concrete to cure, or harden to the desired strength, will take up to three months. 

Crews set the bridge beams on the new County Road 92 bridge over Highway 12

During the week of July 11, crews installed the new bridge beams for the County Road 92 bridge over Highway 12.

Utility and grading work continue  

The rest of the construction zone remains an active area as crews continue their work reconstructing Highway 12 and building County Road 92 in its new alignment.  

During the past few months, project crews completed a significant amount of grading work, adding sand and gravel along the new roadway. All this work helps ensure the roadway will hold up over time.  

Currently, they are installing new storm sewer systems along Highway 12, the roundabout intersection and County Road 92, and a new box culvert on County Road 92. This requires excavation, installation of the systems, careful placement of the culvert and other precision activities that means this work will take around a month to complete.  

The final phase of installing new curbs and gutters, paving and striping the new roadway will follow. We remain on schedule to complete all major reconstruction activities on both roadways this fall.

2022 construction

On Thursday, March 31, Hennepin County returned to the County Road 92 safety improvements at Highway 12 project in Independence for our final year of work.

Begun in 2021, the project will make safety improvements at two locations where County Road 92 intersects with Highway 12. The improvements are the result of both a collaborative engagement and design efforts between the county, the City of Independence, Minnesota Department of Transportation and the Highway 12 Safety Coalition.

Last year, we completed a significant amount of earthwork throughout the project area to stabilize and strengthen the foundations for the new road alignment and bridge on County Road 92. We also constructed the new frontage road and cul-de-sac off along Highway 12. 

In 2022, you will see these county construction activities:

  • Completion of the County Road 92 bridge over Highway 12
  • Completion of the Highway 12 and County Road 92 roundabout
  • A new alignment of County Road 92

We will construct the new intersection in stages to limit impacts for users of both County Road 92 and Highway 12.

Spring to fall: Highway 12 and County Road 92 north leg

On April 18, we have begun work on Highway 12 to construct the new intersection and continue work on the north leg of County Road 92. This work will be weather dependent. We expect to complete construction on Highway 12 in the fall.

Fall: County Road 92 north and south legs

In the fall, crews will continue to work on the north leg of County Road 92 and will return to the south leg, in order to place County Road 92 in its new alignment. We will send out more detailed information about the timing of this work as we have updates to share.

Learn more about the County Road 92 project

The planned improvements at County Road 92 are the result of both a collaborative engagement and design efforts between the county, the cities, MnDOT and the Highway 12 Safety Coalition.

Features of the new roadway include:

  • A new multi-lane roundabout that reduces the two intersections down to one
  • A realigned County Road 92 and bridge over Highway 12 and BNSF Railroad
  • A new County Road 92 curve and intersection at Lake Sarah Road

We will construct the new intersection in stages to maintain as much access as possible on Highway 12 and County Road 92 users. Barring any delays, we anticipate completing all major construction activities by fall 2022.

When complete, the project will provide a better experience and enhance the safety of people driving in the area.
