Traffic Impacts:
During the project, on divided highways, traffic will be reduced to one lane as road work is completed. On two-way highways, traffic will be reduced to one lane and guided with the use of flaggers and a pilot car. Delays of up to 15 minutes should be expected while traveling through the work area during daytime hours.

Loose gravel and fresh oil will be present in the project area for a period of four to 48 hours after each day's chip seal application. Traffic is advised to reduce speed or use an alternate route during this time. The permanent pavement marking is scheduled to be applied within 14 days of completion of the chip seal and fog seal projects.

The prime contractor on this $2.3 million project is The Road Guy Construction Co., Inc. of Yankton, SD. The overall project completion date is Friday, Oct. 16, 2026.
