MOBRIDGE, S.D. - On Monday, April 13, 2026, a project is scheduled to begin on U.S. Highway 12 from Mobridge west approximately 15 miles and on S.D. Highway 1806 both north and south of Highway 12. The Highway 12 project will primarily involve pipe and guardrail corner improvements on the shoulders of the highway.

On Highway 1806 north of Highway 12, work will include mainline pipe installations and short grading sections. Traffic will be reduced to one-half width in these work zones during daytime hours, with flaggers and a pilot car guiding the traveling public.

On Highway 1806 south of Highway 12, work will focus on a slide repair. Traffic will be controlled with stop signs through the work zone. At times during the daytime, flaggers and a pilot car will guide the traveling public.

Commuters should be alert through the entire work zone for workers adjacent to moving traffic, construction vehicles entering and exiting the work zones, and changing traffic patterns.

The prime contractor on this $24.5 million project is Central Specialties, Inc., of Alexandria, MN. The overall completion date for this multi-year project is Saturday, June 20, 2026.
