Irene - S.D. Highway 46 from U.S. Highway 81 to Irene
Project Summary:
This project is a 12-mile-long full reconstruction of S.D. Highway 46 in Yankton County. The project begins at the U.S. Highway 81/S.D. Highway 46 intersections and ends at the west edge of the city of Irene. Work on this project will consist of full roadway grading, structure replacement, culvert replacement, interim surfacing, intersection lighting at U.S. Highway 81/S.D.
