Interstate 90 is closed after a trucker lost the load off his semi Thursday afternoon.
South Dakota Highway Patrol says a semi driver lost control after hitting the shoulder and over-corrected to the median. The semi jack-knifed, shifting the lumber, causing logs to spill onto the interstate.
Both eastbound lanes remain closed as of 5 p.m., but a trooper says the South Dakota Department of Transportation is working to clear one lane.
Traffic is being diverted off at Exit 107.
No one was hurt.
