April 7, 2025 - Press Release:
Beginning on Monday, April 21, 2025, work is scheduled to begin on the U.S. Highway 81 surfacing project between the City of Yankton and S.D. Highway 46. This project includes resurfacing the asphalt shoulders and the four-lane divided roadway north of Yankton.
Work on the project will include concrete surfacing of the newly constructed four-lane divided roadway from 306th Street to 302nd Street, resurfacing the asphalt shoulders adjacent to the existing concrete pavement from S.D. Highway 50 to 306th Street and from 300th Street to Highway 46. The project also includes guardrail widening at the James River Bridge.
Phase one of the concrete surfacing is set to begin on Monday, April 28, 2025. Two-way traffic will be placed in the northbound lanes for the first phase of the concrete surfacing and onto the newly paved southbound lanes for the second phase. Traffic will be moved through the asphalt shoulder resurfacing project using a pilot car, flaggers, and lane closures. Motorists can expect delays during these times.

Dec. 20, 2024:
December Completed Work: Lighting has been installed at the main intersections throughout the project, traffic control for the winter has been installed, and project cleanup continues.
Traffic is directed through the project in their designated lanes by use of traffic control devices. One lane of travel is being maintained in both directions. The speed limit is reduced to 45 mph through the work zone on interim blotter or gravel surface. Travelers will need to drive with caution as the roadway is rough.
Anticipated work in Spring: All remaining erosion control items will be completed along with the remaining project cleanup. After this, the surfacing project will begin.
