LEXINGTON, S.C. — If your commute takes you on Interstate 20 in Lexington, you could be delayed Wednesday morning.

The Lexington Police Department says an overturned semi truck closed westbound lanes on I-20 near mile marker 58 (near exit for Highway 1/Augusta Road).

Highway Patrol says the crash happened around 4:30 this morning and injuries were reported.

Officials began detouring interstate traffic onto Sunset Blvd/U.S.-378.

Around 5:30 am, one lane reopened westbound and traffic is no longer being diverted. However, officials say traffic is slowing eastbound as drivers rubberneck to see the westbound crash.

Troopers say the crash happened as the semi was traveling west on I-20. The truck then ran off the right side of the road and hit a disabled car that was in the emergency lane.

Officials say the car that was hit went off the road into a ditch and the driver was able to crawl out.

The tractor trailer also left the roadway and hit several trees before it jackknifed. This is what blocked the second lane of I-20 westbound.

Troopers say the driver of the car was taken to the hospital with minor injuries.  The driver of the tractor trailer needed to be extracted from the truck, but refused medical treatment.
