S.D. Highway 50 and S.D. Highway 37 - Tyndall

Project Summary:

The project includes approximately three miles of reconstruction on S.D. Highway 50 through Tyndall. Work will begin on the east side of Tyndall at the start of the four-lane divided highway and extend west to just beyond the intersection of S.D. Highway 50 and S.D. Highway 37 South, where the divided highway ends.

The project includes full roadway grading to transition the four-lane divided highway into a five-lane undivided roadway with a center turn lane. Additional work includes new asphalt surfacing, culvert replacement, intersection realignment, roadway lighting and permanent signing to improve safety and traffic flow.
