Seal coats on several hwys in southcentral and southwest MN to begin August 4

MANKATO, Minn. – Motorists are advised to expect delays on hwys 4, 14, 30, 71, 75, 83, 91, 109, 169, and I-90 in southcentral and southwest Minnesota beginning Monday, August 1, weather permitting, as crews apply a seat coat to protect the treated hwys from the harsh Minnesota weather. 

The impacted hwy portions include:

  • hwy 4
    • North of Sleepy Eye, from hwy 68 to just south of 280th Street
    • North of Sleepy Eye, from 280th Street hwy 19 near Fairfax
    • Iowa border to southwest of Sherburn
  • hwy 14
    • Cobden to west of 160th Street
    • Sleepy Eye, from Township Road 318 to County Road 27
  • hwy 30: Amboy to Mapleton
  • hwy 71: Windom to hwy 30 east of Jeffers
  • hwy 75: 1 mile south of I-90 to Luverne
  • hwy 83: 3 miles south of Waldorf to 3 miles north of Pemberton
  • I-90
    • Eastbound I-90 from Sherburn to Fairmont
    • Eastbound I-90 from Worthington to 10 miles east of Worthington
    • Eastbound I-90 south of Lakefield to west of Jackson
  • hwy 91: 4 miles south of Adrian to 7 miles north of Lismore
  • hwy 109: Wells to Alden
  • hwy 169
    • North of Blue Earth to Winnebago
    • Northbound from 1 miles south of Le Sueur to 1 mile north of Le Sueur

Traffic will be controlled with flaggers and a pilot car. Motorists should expect delays, drive with caution, and watch for workers, equipment, and traffic control devices.

The seal coat is a preventative maintenance measure that provides a protective layer, reducing deterioration due to sun and moisture. Drivers are encouraged to slow down and be alert for loose gravel and oil in these areas. 

The sealcoating process for each hwy segment will take one to two days. Crews will then return a couple weeks later to paint final striping, which will be done under traffic.  The entire project will be completed by early September, depending on weather and material availability.
