UPDATE: Riverside Drive to be closed for hours due to gas leak | Video

Atlanta Gas Light officials say it could be noon before Riverside Drive is reopened in the 3500 block where a gas leak has closed the road.

Shortly before 8:30 a.m. a road construction crew broke a gas main near the Ace Hardware store and Waffle House at 3620 Riverside Drive, said John Skvasik, a local supervisor for the gas company.

Crews need to dig up the line and patch it which could take hours, Skvasik said.

Workers inside the Georgia Department of Labor Vocational Rehabilitation office were told to evacuate the building until it could be checked for leaking gas, said Ed Leysath who works inside the office.

The road is closed from Tom Hill Senior Boulevard and Arkwright Road to Northside Drive, although cars are being allowed to travel to the Social Security office and the North Macon Medical Complex, said Capt. Kenny Nobles of the Macon-Bibb County Fire Department.

Firefighters are standing by to assist the gas company in case of emergency, Nobles said.

Although the Ace Hardware store and Waffle House remain open, customers can not drive to the buildings.

"We never close but the leak is keeping anybody from getting to us unless they walk or ride a bicycle," said Raschard Bradley, Waffle House manager.
