It was extinguished around 1 p.m.Police haven't said what caused the tanker to leak fuel and catch fire, but Doug Thomas told Local 4 his brother, Ron, was the tanker's driver and got cut off by another car. Thomas said his brother was forced to swerve and hit a wall."As he was hitting the wall, the sparks ignited the fuel, I guess. Or, took the hoses off," Doug Thomas said.Eyewitness Damus Manover said he was driving behind the tanker and saw it make an abrupt move out of the center lane."I had to make a quick right turn to duck the debris, and (I was) afraid to get blown up in an explosion," Manover said.No one was seriously injured
