A four vehicle accident on Interstate 20 Monday closed the highway for about five hours. Palo Pinto County Emergency Management Coordinator Buddy Harwell said a truck carrying sod from Dublin to Keller lost part of its exhaust stack, resulting in a fire along the Interstate that also caught the cab on fire. "Around 11:57 a.m., there was a call that there was a truck on fire on I-20 near the Erath County line," explained Texas Department of Public Safety Trooper Gary Rozzell, DPS information officer. He said the truck pulled to the right shoulder on the eastbound side of the Interstate. "Other traffic started slowing down," he continued. "Approximately a half mile back in traffic, on the right hand side, was a truck-tanker." In the left lane was a U-Haul box truck pulling a trailer with a vehicle on it. It was followed by a mini-van. "In the traffic came a Dodge pickup in the left lane, it rear ended the mini van, spun it into the truck puncturing the fuel tank," Rozzell related." The Dodge continued into the trailer and went on the left rail of the flat bed trailer. The U-Haul trailer detached." He said the Interstate was shut down for the fire, but remained closed for the danger associated with Xylene, the tanker's cargo. "The tank was empty but had fumes," Rozzell said. "Because of that we waited for hazmat," he said.
