LENNOX, S.D. – On April 20, 2026, S.D. Highway 44 closed from the south side of the Oriole Avenue intersection to the intersection of Highway 44 (280th Street) to begin grading work by Lennox.

 A signed detour route is available using 465th Avenue on the west side of Lennox and 280th Street to travel east and west on Highway 44.

 The project includes several roadway improvements on Highway 44. The north/south segment from 279th Street to 280th Street will be reconstructed with two 12-foot lanes, a center turn lane, eight-foot shoulders, and roadway lighting. The east–west segment from 280th Street to Interstate 29 will be milled and resurfaced.

 The prime contractor on this $5 million project is Central Specialties, Inc. from Alexandria, MN. The overall project completion date is Friday, Oct. 30, 2026.
