With overnight temperatures below freezing expected, crews with the Texas Department of Transportation were hard at work Monday getting roads ready for a long, cold night.
“What we're treating are the elevated structures; bridges, over-passes,” said Rickey Daley, TX DoT spokesman. “In cold weather, those will be the first to freeze if we get any precipitation.”
But these crews had a new solution in mind; brine.
“It's a 23% salt solution in water, you'll see it as white stripes on the road,” said Daley. “It's good for about three days.”
According to TX DoT, brine lowers a bridge's freezing point, keeping ice away longer when rain and cold mix.
Treatments started over the weekend on U.S. 77 and Interstate 37 as well as other roads. Crosstown Expressway and the JFK Causeway were 'brined' Monday.
It’s part of a test drive for TX DoT to keep roads safe this winter and down the road.
“That bridge you go over at Noon, if you get precipitation and you get freezing temperatures, at 6 or 7 o'clock at night, it could be a completely different situation,” said Daley.
