One person has died following a crash in Cumberland County this morning.

The Tennessee Highway Patrol says that around 4:00 a.m. a tractor-trailer overturned on 40 West near mile marker 327.

THP says two vehicles were involved and that westbound lanes had to be shut down with traffic being diverted to exit 329 near Crab Orchard.  We understand at least one lane west bound is open now with both lanes to be clear by noon today.
