The Oklahoma Turnpike Authority deployed their largest snowplows on Sunday, including all of their massive snowplows, pulled by trucks called "tow plows".
Together they cleared 26 feet of highway in one pass. It's so big the road has to be blocked behind it because no one can pass. Working with other plows, an entire highway can be cleared at once. The turnpike authority has 15 of the tow plows, working their 11 turnpikes.
Each rig costs $250,000.
