Kentucky State Police say northbound Interstate 65 in Hart County will be blocked for several hours because of a deadly crash early Tuesday.

The accident involves multiple commercial vehicles at the 65 milemarker in the northbound lanes.

Drivers headed northbound on I-65 are advised to exit at exit 58, or Horse Cave, onto Kentucky 218 then onto U.S. 31W north to Kentucky 728 in Bonnieville. Traffic will re-enter I-65 northbound in Bonnieville at exit 71.

State police say long delays should be expected.
