The driver of a car that plowed into a construction site on I-20 early Friday may have been impaired, the Georgia State Patrol said.

A construction worker was killed and three others were injured in the crash, which shut down westbound lanes of I-20 in Carroll County for more than two hours.

About 3:10 a.m., a westbound Honda Civic drove onto the north emergency lane and hit the construction crew members, who were working between the interstate and the exit ramp for Ga. 61, according to the GSP.

One of the construction workers was pronounced dead on the scene. Two others were taken to a hospital in Atlanta, one by air and the other by ambulance. A fourth construction worker was treated and released from Tanner Medical Center in Villa Rica.

The driver, who had to be freed from the mangled Civic, was flown to an Atlanta hospital, the GSP said.

While authorities suspect the driver was impaired, they have not specified if the driver was under the influence of alcohol, drugs or something else.

All lanes reopened about 5:30 a.m., according to the WSB 24-hour Traffic Center.
