Highway reopened after 140-car pile-up in Texas

(NECN) - The Thanksgiving holiday turned tragic in Texas, where two people were killed and dozens more hurt in a massive, chain-reaction crash.

Authorities say at least 140 vehicles were involved in the pile-up in Southeast Texas.
    
Extremely dense fog is being blamed for the collision.
 
A man and a woman were killed in an SUV when a tractor trailer crushed their car.
   
One woman who survived the crash ran back to see if she could help a family behind them, but the cars kept piling up.

All lanes on the highway were closed for about eight hours, but are now back open.
