A wreck that almost took up seven and a half hours finally cleared Friday morning before the bulk of the commute traffic began to flow.
Around 9:30 p.m. Thursday night, an 18-wheeler traveling in the southbound lanes of I-65 swerved into the median before over correcting and crashing through the guard rail on the west side of the interstate.
Officials said it took about an hour to remove the driver from the 18 wheeler.
The crash occurred about a mile north of Exit 365 to Ardmore.
State Troopers on the scene said it took about an hour to remove the driver from the truck. He was then taken to a helicopter pad in Ardmore before being flown to Huntsville Hospital in serious condition.
It took crews several more hours before they were able to flip the truck and remove it from the ravine, in which it was lodged.
Officials said the truck was carrying construction equipment.
At certain points throughout the night, one southbound lane was able to be opened, but was then shut down again.
The scene didn't completely clear until shortly before 5 a.m.
What caused the driver to go off the road is still under investigation.
