Oct 23 (Reuters) - A Louisiana "super fog" aggravated by marsh fires led to a pile-up of 158 cars just west of New Orleans on Monday that killed seven people, injured at least 25 and left a string of crumbled and charred vehicles on a bridge over Lake Maurepas, officials said.
At least one vehicle went over the edge and lay sideways in the water, pictures posted by the Louisiana State Police showed. The search for victims from the chain-reaction accident continued for hours after the crash, the state police said on Facebook.
A fire broke out in part of the crash scene, forcing emergency responders to off-load hazardous materials from a tanker truck, the state police said. The accident closed Interstate 55 in St. John the Baptist Parish.
