Previous story

It could be several days before all lanes of I-75 South reopen between Emory Road and Callahan Drive in Knox County.

A large pothole opened up early Tuesday morning, causing flat tires for several drivers before crews could get the right lane closed to traffic.

TDOT says crews are working on the repairs. The damaged concrete around the hole will be removed and structural repairs will be made before new concrete is poured.

The right lane may remained closed for several days, depending on the weather.

The weather, by the way, is most likely responsible for this and the many other potholes opening up on area roads. TDOT says this time of year, with freezing and thawing conditions, potholes and rockslides are frequent and unavoidable. However, as soon as TDOT is notified of a problem that could pose a danger to drivers, they work to get it repaired as quickly as possible.

We're told that just before 7 Tuesday morning several motorists hit the hole, causing their tires to go flat.

Crews are working to repair and fill the hole and according to TDOT they hope to have that section of interstate back open by 9:00 a.m. Tuesday morning.
