Hwy 22

Mapleton - Mankato

Traffic Impacts

Road closures

  • Begins March 27, 2017 - Ends October 2017 for the winter.
  • 2017 Detour will be necessary for southern segment to replace bridges, culverts and where pavement is reconstructed. The detour includes Highway 30, Highway 83 and Blue Earth County Road 90.

 

  • MnDOT encourages people to use the official detour for the following reasons:
    • The pavement on the detour routes is designed for heavy trucks and large traffic volumes.
    • The detour route has better safety features including wider shoulders, gentler curves, and clear signing.
    • Using other routes may result in more maintenance and dust problems for local road authorities.
  • However, Highway 22 north of County Road 16 is a public road that is open to traffic so it is not illegal to drive on it.
  • Please use the official detour to reduce the negative impacts of using local roads.
    • 2017 Detour Frequently Ask Questions
      • Will MnDOT make the intersection of Hwy 22 and CR 90 a 4-way stop?
        In response to drivers on CR 90 assuming that southbound Hwy 22 traffic also has a stop sign, MnDOT has added these signs:
        • Westbound CR 90: TRAFFIC FROM RIGHT DOES NOT STOP
        • Eastbound CR 90: TRAFFIC FROM LEFT DOES NOT STOP
        • Northbound Why 22:  ONCOMING TRAFFIC DOES NOT STOP

        Converting the intersection to an all-way stop is an option, but will be a last resort.  If converted, CR 90 traffic could become accustomed to all Hwy 22 traffic stopping during the seven-month long detour.  When the through-stop configuration is restored in the fall, high-speed right angle (T-bone) crashes could occur if the CR 90 traffic fails to remember the intersection’s traffic control has reverted to the pre-construction configuration.

        We will continue to monitor the intersection to see if the additional signs help, and will continue to take steps to improve motorist compliance if necessary.

      • Can I access Hwy 22 from Blue Earth CR 10 in Beauford? Sorry, no. Construction will be taking place through the intersection and north of the intersection that would make it unsafe for the traveler and the construction workers.
      • Where can I cross Hwy 22? Any roads north of and including CR 16 will be able to cross Hwy 22 this season. Crossing roads south of CR 16 to just north of Mapleton will be dependent upon on the contractor's operations. Typically, only one crossroad will be closed at a time.
      • Can I travel on the north section (Hwy 22 between CR 16 and CR 90)? You can travel on Hwy 22 north of CR 16 if you are a local traveler.
      • How do I access businesses south of CR 90? You are allowed to drive around the barricades at CR 90 to reach these businesses - and they will all be open and appreciate your business! Please note the addition of a STOP sign for northbound traffic on Hwy 22 south of the barricade.
      • How do I access businesses & church in Beauford? You will be allowed access to businesses and the church by entering the work zone at the closest point - CR 10. Please use extreme caution in this area.
      • How do I access businesses in Mapleton? Work on Hwy 22 in Mapleton will not include a reconstruction at this time - only a resurfacing later in the season, so it will be safe for you to enter from the south junction of Highway 30 or any of the crossroads in town. Please continue to frequent the Mapleton businesses!
      • What if I live in the construction zone? You will be provided access by the contractor - Mathiowetz Construction.
      • REMINDER - It is illegal to travel "through" the fully-barrided road closed construction zone and law enforcement can ticket motorists. It is a misdemeanor with fines up to $1000 and/or 90 days in jail. The reason for this law is to keep both motorists and workers safe.
  • 2018 Detour will be necessary for northern segment and construction of roundabout at Hwy 22 and CR 90
