SIOUX FALLS, S.D. (AP) - Authorities are investigating whether icy conditions played a role in a crash that killed a man on the interstate near Humboldt.
The South Dakota Highway Patrol says the 54-year-old man lost control of his car on Interstate 90, traveled into the median and flipped over. The man died at the scene of the crash Wednesday, a day in which icy conditions caused numerous accidents, including another near Beresford in which a semi rolled over on Interstate 29 and blocked traffic.
Treacherous travel is also expected this weekend. A winter storm watch is in effect for much of the region from Friday night through Sunday morning.
The National Weather Service is expecting 5 to 9 inches of snow in parts of southeast and central South Dakota with up to 11 inches further south.
