UPDATE: Aall lanes of traffic have returned to normal after tractor-trailer overturned on I-75 south just past the 75/24 split, which closed the southbound lanes for several hours Wednesday.

TDOT says the southbound lanes are blocked and traffic is slowly passing on the left shoulder. 

The tractor-trailer has been cleared, but officials are still working to clear debris. 

TDOT hopes to have the roadway cleared by 2:36pm, according to their SmartWay website.
