The eastbound lanes of Interstate 94 have reopened after being closed for several hours after a tanker carrying milk overturned in the Lowry Hill Tunnel in downtown Minneapolis.

The tanker was headed westbound on 94 around 11:15 a.m. when it struck the concrete median and flipped over onto the eastbound lanes, spilling milk on the highway, said Lt. Eric Roeske of the Minnesota State Patrol.

At least three other vehicles were involved in the crash. The truck driver and one other person were taken to the hospital, Roeske said.

Authorities shut down eastbound 94 and traffic was diverted on to exits for westbound 394 and Lyndale Avenue. Long backups continued into early afternoon.

Westbound lanes of 94 were closed briefly after the crash, but then reopened.
