PIERRE, S.D. – The South Dakota Department of Transportation (SDDOT) says chip seal and fog seal projects are scheduled to begin on S.D. Highway 204 and S.D. Highway 1804 in the Pierre Area. Crews will begin chip seal and fog seal projects on Monday, July 18, 2022. The project length is approximately two miles on Highway 204 and 31 miles on Highway 1804, beginning at mile marker 251.


Weather dependent, the contractor will move from one project to the next in the scheduled following order:

  • Project begins at the turnoff to Cow and Spring Creek and proceeds south to Highway 204.
  • Sealing of Highway 204 in its entirety is then planned.
  • Project will seal Highway 1804 to the junction of U.S. Highway 14.
  • Contractor then proceeds back north to the end of the project and finishes the remaining leg to Cow and Spring Creek.

 The chip seal will take approximately five days and then the fog seal two days to complete.


On the two-lane routes receiving a chip seal and fog seal, the traffic will be reduced to one lane and guided through the project with the use of flaggers and a pilot car. A delay of up to 15 minutes can be expected while traveling through the work area during daytime hours.


Loose gravel could be present for a period of 36 to 72 hours after each day’s chip seal application. Traffic should travel at 40 mph or the speed limit, whichever is less, during this time frame. The permanent pavement marking is scheduled to be applied within 14 days of completion of the chip & fog seal projects.


The prime contractor for this $1.6 million project is Jensen Rock & Sand, Inc. of Mobridge, SD.
