A Virginia acid spill is much larger than originally thought.Preview: One person is dead following an overnight crash on the Inner Loop of the Beltway in Fairfax County. The VSP says a tractor-trailer loaded with produce had slowed up for delays approaching a work zone near the Old Dominion overpass shortly before 2:00 this morning when a car slammed into the back of it. The car went partially under the trailer and the passenger cabin was completely destroyed. The crash shut down the Inner Loop for about four hours.
