Blount County dispatchers say all lanes of Alcoa Highway reopened around 1:40 pm.
The northbound lanes of Alcoa Highway are shut down Friday afternoon, after an accident involving a dump truck.
The accident was reported around 11:40 am near Wheeler Road in Blount County, close to the Kia dealership.
The dump truck, which was carrying a load of dirt, overturned, blocking the roadway.
Emergency officials aren't sure how long the road will be closed. Pellissippi Parkway is the preferred detour around the closure.
