For a few minutes Tuesday morning a Rockdale intersection could have passed for a Yellowstone thermal feature with natural gas bubbling up through a pool of water. Just before 8 a.m. a city crew fixing a water leak inadvertently cut a 2-inch gas line at MLK and Seventh, according to City Manager Randy Holly. Firefighters and police were called and a family with an infant was briefly evacuated. An Atmos Energy crew repaired the line. No injuries were reported.
