Part of Interstate 65 in northwest Indiana was shut down Saturday night, after a milk truck overturned near Lowell.

Indiana State Police said the truck overturned about two miles south of the Lowell exit, ending up in a field off the expressway.

The northbound lanes of I-65 were closed near Lowell as crews work to offload the milk from the tanker before the truck is towed away.

Northbound traffic was being diverted off I-65 at Indiana State Road 10 (Exit 230).
