A tandem semi, enroute from Indianapolis to Vincennes, overturned on I-70 near the 25-mile marker westbound before dawn Tuesday. The truck was carrying sodium chloride, a hazardous, flammable material. When officials arrived on the scene, the driver asked for a hazardous materials team to be called to the accident. At 8:30 a.m., a Clay County Sheriff's Department spokesman told The Brazil Times there were no plans to evacuate residents in the area of the spill. The driver, whose name was not released as of press time, received some scratches and bruises, but was not seriously injured. He was able to exit the semi tractor without assistance. The driver told police the trailer's wheels on the passenger's side left the roadway, into some melting snow, and the driver was not able to get them back onto the highway. Traffic on I-70 was slowed for 2 1/2 miles when the accident occurred. Traffic was stopped when the hazardous materials team arrived, because of the fire potential.
