The North Texas Tollway Authority has released video showing last month's deadly tornado crossing the highway.
Cameras posted at the Interstate 30 and President George Bush Turnpike interchange captured the massive tornado in the glow of lightning.
Another angle shows high winds pushing debris across the roadway.
Of the 11 people who died during the severe weather on Dec. 26, five of those were driving along I-30 near the turnpike in Garland.
The National Weather Service determined it was an EF-4 tornado and that 11 others touched down around North Texas.
The cleanup is expected to take 10 weeks or more.
