Four people were killed in an accident on I-20 tonight that shut down all of the east bound lanes. It happened around 5 o'clock in Gregg County, one mile east of highway 135 near Liberty City. DPS troopers say a tan 4-door Toyota traveling in the west bound lane of I-20, lost control, crossed the median and hit head-on a gooseneck trailer carrying heavy equipment. The four passengers in the Toyota were dead at the scene. Authorities say the driver of the trailer is in good condition. All the east bound lanes were closed for at least three hours while the scene was being cleaned up.
