A semi-trailer truck overturned on southbound Interstate Hwy. 35W at Hwy. 10 shortly before noon Monday, blocking two lanes and causing traffic to be re-routed. The eastbound Hwy. 10 ramp is also closed.

A Minnesota State Patrol spokesman urged drivers to take alternate routes.

The semi was carrying auto parts, and cleanup was expected to take some time.

No one was injured in the accident, officials said.
