Travel Impacts:
Motorists should expect delays and periods where traffic will need to drive on dirt surfaces. A temporary gravel service road will be constructed from Interstate 90 to S.D. Highway 248 to provide access to local businesses. Wet weather may cause the roadway to become impassable, requiring temporary closures until the surface is safe again. For updates on road conditions and possible temporary closures for Highway 73, please visit https://SD511.org.
