All lanes on Interstate 12 eastbound near the O’Neal Lane exit are now open.
The earlier closure was caused when an 18-wheeler jacknifed around 3:30 p.m., State Police spokesman Russell Graham said.
The driver of the 18-wheeler was following a vehicle in front of him too closely, Graham said.
The car ahead slammed on its brakes, which caused the truck driver to lock his brakes while trying to avoid rear-ending the vehicle, Graham said.
The incident happened in an area full of construction and concrete barriers, Graham said.
Traffic has backed up quickly because the accident happened during rush hour times, Graham said.
No one was injured, Graham said.
State Police are working to clear the scene and advise taking an alternate route.
