S.D. Highway 11 North of Brandon

Project Summary:

The project will reconstruct approximately one and one-half miles of roadway, including replacing two bridges over West Pipestone Creek and Split Rock Creek.

The roadway will be raised approximately 10 to 12 feet through the low-lying valley to reduce flooding impacts and improve long-term reliability. Once complete, the new asphalt surface will provide a smoother ride for motorists and help reduce future maintenance needs.

Anticipated Work - April 2026:

Contractor crews will continue grading outside the shoulders along S.D. Highway 11, County Highway 130 and 257th Street. Highway 11 and Highway 130 will remain open until after Monday, June 1, 2026, though drivers may see closures at the intersections of 257th Street and Palisade Street before that date.

Multiple utility companies are also working on relocations along Highway 11 and Highway 130.

In March 2026, the contractor began grading outside the shoulders and started hauling borrow material from pits near Knife River. Metal pipe culverts were installed in field approaches and driveways. Utility companies have been relocating gas, fiber and electrical lines.
