Crews from both states worked to reopen westbound I40 early Sunday. The eastbound lanes of the interstate have not been affected.
The mud slide in Tennessee happened Tuesday in Cocke County just over the state line, while the Friday rock slide in North Carolina happened around mile marker 7.
A massive rock slide on I-40 in North Carolina in October 2009 closed the interstate for six months.
The DOT said traffic should flow normally on I-40 West through North Carolina. However, motorists crossing into Tennessee will see the road narrow down to one lane at the site of the rockslide.
