BUCKHEAD, Ga. — Traffic was blocked for more than five hours on Interstate 20 in Morgan County after a crash Wednesday.

Three people were injured in the crash at 10:14 a.m., about 3 miles east of the Madison/Eatonton exit.

A mechanical failure in one of the three involved trucks — two commercial vehicles and a pickup — was the reported cause, the Georgia Department of Public Safety said.

The trailer of the first commercial vehicle separated from its power unit and came to rest in the eastbound lanes of the interstate. A second commercial vehicle, then a Ford F-250, struck the trailer.

The driver of the second commercial vehicle — 55-year-old David Andrukevich, of Hamden, Connecticut — became trapped and had to be extricated from his truck. He was transported to Piedmont Athens Regional Medical Center.

The driver of the Ford — 33-year-old Robert Coleman, of Alpharetta — was injured and transported to Morgan Memorial Hospital in Madison.

James Overton, 32, of Jackson, South Carolina, was the driver of the first truck.

The interstate was closed until 3:23 p.m.
