I-40 westbound is shut down in Cumberland County because of a crash.
According to TDOT, the crash was reported around noon (eastern) at milemarker 333, just east of the Crab Orchard exit.
The Tennessee Highway Patrol says a tractor trailer has overturned and trapped another vehicle. There's no word on any injuries. Officials do not know what the truck was carrying, but something is leaking, so a hazardous material team has been sent to the scene.
Westbound traffic is being diverted at exit 338 onto Hwy. 70.
The eastbound lanes are open, but TDOT says there are "rubbernecking" delays.
