COLUMBIA, S.C. — An overturned tractor  blocking multiple lanes of traffic on Interstate 20 in Columbia for several hours Tuesday afternoon

The crash was at mile marker 64 at the bridge on I-20 West at I-26 (exit 107). 

Video from the scene showed the big rig on its side. Crews were able to quickly open up a lane so that some traffic could get through while they worked to move the trailer from the road. 

It's not clear what led up to the accident. The South Carolina Highway Patrol's website said there were no major injuries.
