Highway 6 near the south city limits of Calvert was closed for more than four hours Thursday night into Friday morning following a three vehicle crash.
The initial DPS investigation indicated a northbound semi-trailer was attempting a U-turn on Highway 6 near Coopers Lane when it was struck by two cars.
A 1984 Corvette was trapped under the trailer. That driver, 19 year old Julian Oldham of Crowley, was flown to a Bryan hospital with incapacitating injuries.
The driver of the other car and the driver of the semi were not injured.
The crash was reported Thursday around 10:10 p.m. and the highway reopened to all traffic Friday at 2:40 a.m.
