A private contractor is working on cleaning up and removing some 4000 gallons of liquid asphalt that spilled along LA 13 in the heart of Pine Prairie after an 18 wheeler flipped over early Saturday morning. Pine Prairie Mayor Terry Savant said he was notified that the driver of the 18 wheeler apparently fell asleep at the wheel at 2;30 Saturday morning.  Beside the 4000 gallons of liquid asphalt,  the accident ruptured the trucks fuel tanks causing a large amount of diesel to spill. Haz Mat teams were called in initially.  A large part of the business district in Pine Prairie was closed for a time over the weekend and motorists were detoured  while work crews were  busy cleaning up the spill. The matter has been turned over the State Department of Environmental Quality . Today’s rains are hampering and delaying the cleanup work according to Mayor Savant.
