Crews clear wreckage after ‘superfog’ near New Orleans causes highway crashes that killed at least 7

NEW ORLEANS (AP) — Crews worked through the night clearing the wreckage of more than 150 vehicles involved in a series of crashes on Interstate 55 near New Orleans caused by a “superfog” of marsh fire smoke and dense fog that killed at least seven people and injured another 25. Hazardous driving conditions Tuesday morning prompted several schools in the area to close or delay. Louisiana State Police say an estimated 158 vehicles were involved and 25 people injured, warning the death toll could climb as first responders looked for victims. Louisiana Gov. John Bel Edwards issued a call for blood donors and asked for prayers “for those hurt and killed.”
