Crews painted double yellow centerline stripes and triangular yield lines in the median of Highway 14 and Olmsted County Road 3 on Oct. 21, 2022 as part of increased safety measures to remind motorists of traffic at the intersection east of Byron.  MnDOT is scheduled to install oversized Intersection Ahead warning signs along Highway 14 as well. Those signs will be equipped with flashers later this season.

The work is part of an overall interim plan to improve safety at Hwy 14 intersections west of Rochester.

Construction work to close the Hwy 14 medians at Olmsted Co. Rd. 44 and 7th St. NW west of Rochester was completed in late July 2022..

MnDOT maintenance crews removed the pavement along the medians as part of an interim safety effort aimed at reducing high-speed, right-angle crashes (T-bone crashes) until an interchange can be funded and built at Co. Rd. 44. Removing the option for traffic to cross Hwy 14 at these two intersections will reduce the chance of these types of crashes, which often cause serious injuries or death.

MnDOT’s decision to close the two medians is an interim safety measure until an interchange crossing can be funded at Co. Rd. 44. MnDOT and Olmsted County are working in partnership on a design and will have plans ready whenever funding might be secured.

The safety work will be occurring along the Hwy 14 corridor both this year and in 2023. Plans call for:

Hwy 14 and 7th St. NW

  • Permanently close the median at 7th St. NW.
  • Vehicles will still be able to exit and enter, however not cross Hwy 14.
  • Not allowing vehicles to cross the roadway helps prevent T-bone crashes. These kinds of crashes often result in serious injuries or death.

Hwy 14 and Olmsted Co. Rd. 44

  • Permanently close the median at Hwy 14 and Olmsted Co. Rd. 44.
  • Vehicles will still be able to exit and enter, however not cross Hwy 14.

Hwy 14 and Olmsted Co. Rd. 3

  • Construct a J-turn at Hwy 14 and Olmsted Co. Rd. 3 in 2023
  • Vehicles will exit and enter Hwy 14, but only be able to cross the roadway at designated U-turn sections.
  • This change stops vehicles from going directly across and significantly reduces T-bone crashes. It also allows for vehicles to cross over the roadway.
  • Other interim safety changes, like the installation of flashing warning signs to alert drivers at the intersection and additional pavement markings, will be installed in 2022 to help draw driver’s attention to the crossing.

Hwy 14 and Country Club Rd.

  • Delay the closure of Country Club Rd. until the J-turn at Olmsted Co. Rd. 3 is constructed in 2023. That construction is expected to take place from April 17-June 18, 2023.

High-tension cable median barriers

  • Continue with the installation of the high-tension cable median barriers along the Hwy 14 ditch in 2023
  • This change will not affect safety at intersections, but can reduce head-on cross-over crashes, which often result in serious injuries or death.

MnDOT will continue to collaborate with our partners at Olmsted County on funding options for a future interchange and interim safety measures.

Future of Hwy 14 and Olmsted Co. Rd. 44

Olmsted County, in partnership with MnDOT, is planning improvements at Co. Rd. 44 and Hwy 14. The project is looking into long-term solutions that improve safety while accommodating future growth. Different interchanges are being analyzed along with other options. A public meeting was held on June 30, 2022. Information about the development of this project can be found on the Olmsted County project web page. Additional outreach is planned to ensure the public and nearby businesses and residents have information about the project as the work progresses.

Traffic impacts

Olmsted County Road 3 traffic will be detoured during some of the J-turn construction work at the intersection in 2023. Details will be posted in early 2023.
