Motorists are advised to expect delays in parts of southwest Minnesota beginning Monday, August 1, weather permitting, as crews apply a seat coat to protect the treated highways from the harsh Minnesota weather.
Impacted highway portions include U.S. 71 from Windom to Minnesota 30 east of Jeffers; U.S. 75 from one mile south of Interstate 90 to Luverne; 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; and Minnesota 91 from four miles south of Adrian to seven miles north of Lismore.
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 highway 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.
