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.

During construction, the highway will be closed to through traffic.

IRENE, S.D. – The South Dakota Department of Transportation (SDDOT) says that S.D. Highway 46, from U.S. Highway 81 to the west edge of the city of Irene, is scheduled to reopen to through traffic on Friday, Dec. 15, 2023. This portion of Highway 46 has been closed to through traffic since April 2023.

The temporary interim surfacing consists of a chip sealed blotter for the first four and one-half miles east of the Highway 81 junction. The remaining seven and one-half miles will be gravel surfacing treated with dust control chloride. Motorists should expect a rough road, loose gravel, and no pavement marking for the gravel surface portion of the project. A posted reduced speed limit of 55 mph will be in effect for the entire length of the project until final paving operations are completed during the summer of 2024.

The prime contractor will be responsible for maintenance of the gravel surfacing, with snow and ice removal operations to be performed by SDDOT crews.
