Most of Jimmie Dyess Parkway has reopened to traffic after workers stopped a gas leak just south of Interstate 20.
Both southbound lanes and one northbound lane of traffic have reopened, said Columbia County Emergency and Operations Director Pam Tucker in an email.
Martinez-Columbia Fire Rescue staff, along with the Columbia County Sheriff's Office, kept the lanes closed while awaiting repair of a cut natural gas line that created "a large vapor cloud."
A contractor laying telephone line hit a high-pressure gas line just before 10 a.m. to cause the leak, Tucker said.
No buildings are being evacuated because of the leak, Tucker said, because the only building affected already is unoccupied.
