At least two people were killed in an estimated 100-vehicle pileup that forced the closure of Interstate 10 in Southeast Texas Thursday, officials said. Dozens were injured.
The collision happened around 8 a.m. on I-10 near Beaumont, about 80 miles east of Houston.
The Texas Department of Public Safety said at least 100 cars and trucks crashed in extremely dense fog.
Several big rigs and a charter bus were involved in the collision.
The Texas Department of Public Safety said the injured were taken to hospitals between Baytown, Port Arthur and Beaumont.
Investigators say there are three "pods" of accidents. One has been cleared, but two others are still active.
Interstate 10 was shut down in both directions for hours. The westbound lanes reopened at 12:30 p.m. When traveling eastbound, motorists are advised to use Highway 124 and Highway 73 in Winnie to avoid the traffic build up.
The eastbound lanes are expected to be closed for 8 to 10 hours.
