Icy road conditions are being blamed for a milk tanker rollover accident on Tuesday that caused 6,000 gallons of milk to spill into a creek in southeastern Minnesota. It happened at around 3am Tuesday just south of Interstate 90 near the town of Elkton. The road was reportedly covered with about an inch of ice at the time. The thousands of gallons of milk poured into Schwerin Creek after the crash, prompting a witness at the scene to say that it looked like “a giant milkshake.” Environmental specialists from the Minnesota DNR and Pollution Control Agency were called to assess the contaminated water. The truck driver was treated for minor injuries and released.
