Wet weather causes sinkhole to form on I-90

May 6, 2024

CHAMBERLAIN, S.D.–While the recent rain has been welcome for many, it has caused some issues near Chamberlain.

A sinkhole has formed on the Interstate 90 business loop between Chamberlain and Oacoma, resulting in traffic being reduced to one lane.

The Department of Transportation had originally planned to start construction in that area next year, but will now speed up their plans.
