  1.  S.D. Highway 75 – Project begins north of Highway 20 to the North Dakota state line. The chip seal and fog seal will take place Wednesday, July 21, 2021, through Saturday, July 24, 2021.
  2.  U.S. Highway 85 – Project begins 10 miles north of Buffalo and will continue north for six miles. The chip seal and fog seal will take place Saturday, July 24, 2021, through Monday, July 26, 2021.

Traffic will be reduced to one lane and guided through all projects with the use of flaggers and a pilot car. Delays of up to 15 minutes can be expected while traveling through the work area during daytime hours. The contractor will be working Monday through Saturday for the duration of the projects.


Loose gravel will be present on all projects for a period of 36 to 72 hours after each day’s chip seal application. Traffic is advised to travel 45 miles per hour or the posted speed limit if it is less than the advised speed during this timeframe. Permanent pavement striping is scheduled to be applied seven days after the chip seal on each project.
