Fire officials told the Oakland Tribune (http://bit.ly/J38926) the line was capped Tuesday, about three hours after the leak was reported.
Pacific Gas & Electric Co. spokesman Jason King told KRON4-TV the utility responded to the scene and found a 4-inch plastic gas main had ruptured.
At one point television news footage showed flames coming from below the roadway. The fire was near homes located several blocks from Interstate 580.
