Construction is broken into three phases and covers two construction seasons.
Phase one starts at the east edge of Beresford and ends at the S.D. Highway 11/S.D. Highway 46 intersection. Work in phase one will be completed during the 2024 season with an interim completion date of Nov. 2024.

During construction, the highway will be closed to thru traffic. Access to residents and landowners adjacent to the project will be maintained, but travelers are encouraged to use the signed detour route around the project. The detour route around the project for phase one includes Interstate 29 to Lincoln County 152 and Highway 11. Phase two detour includes Highway 11 to Lincoln Co 152 and Lincoln Co 143.
