Chicken fat clogged a major traffic artery in Louisiana Tuesday, a day after a leaky truck left a stinky, slippery trail along a one-mile stretch of an interstate highway. Crews spread sand over the spill, which was mainly in one eastbound lane, and worked Tuesday to scoop up the mess and keep it from oozing farther on the concrete bridge deck, Kelly said. Traffic was able to use the second lane. A second truck was brought in to transport the remaining fat. The spill was considered noxious but not toxic, according to a hazardous materials officer, Monroe fire officials said. It was not immediately clear where the fat originated.
