The latest I-20 wreck happened about 10 am Thursday in the westbound lanes near mile 11, the Graniteville exit area.
It involved a delivery type truck and another vehicle.
The smaller vehicle flipped onto its side at the side of the road.
State troopers called in a helicopter to take the injured to the hospital.
Traffic was slowed quite a while by the mess.
There's no word yet from the patrol on the events leading up to the wreck, but traffic is now moving normally again.
Much earlier Thursday morning, a truck loaded with steel wrecked on I-20 a few miles away.
The trucker may have fallen asleep, and the 18-wheeler flipped, spilling the load of beams.
Both westbound lanes were blocked for a little while, but one lane was opened pretty quickly.
The trucker is not seriously hurt.
It happened at about the 8 mile marker.
