Authorities said a Mack truck registered to an Irving company slammed into several vehicles on Interstate 35 near Gainesville, killing three people.
Two people were also injured in the multivehicle wreck that shut down Interstate 35 for seven hours.
The crash occurred at about 11:55 a.m. in the northbound lanes at the Elm Creek bridge near FM 1306, where bridge maintenance had narrowed the two lanes to one.
DPS Trooper Mark Tackett said an 18-wheeler driver by James Crayton, of Dallas, apparently did not slow before it hit the first vehicle. The car exploded on impact, killing Anthony and Kimberly Brandon, of Bedford.
Crayton's truck then slammed into a Honda Accord driven by Carol Whaley, 63, of Yalaha, Fla., injuring him and his wife, Linda, 61.
The 18-wheeler then hit another vehicle, ramming it into the rear of another 18-wheeler. The driver of that vehicle, Darryl Hoosier, 55, of Lafayette, La., was killed.
The driver of the second truck was not injured.
