A resurfacing project began on U.S. Highway 81 in Watertown on April 8. The project area stretches from a quarter mile north of 20th Avenue SE in Watertown to the east junction of S.D. Highway 22 and Highway 81. The 10-mile project includes cold milling asphalt concrete, asphalt concrete resurfacing, and culvert repairs.
Highway 81 will remain open to traffic for the entirety of the construction project. Traffic will be controlled by a pilot car and flaggers once milling and asphalt overlay begin. The primary contractor for the $6.1 million project is Duininck of Watertown.
Work is expected to be completed by October 2025.
