Go Behind the Barricades With Operation Freeze

The Tucson Department of Transportation (TDOT) Streets and Traffic Maintenance Division initiated Operation Freeze earlier this week. The program makes sure bridge decks are free of ice and safe for motorists to use.

During Operation Freeze, TDOT crews spray magnesium chloride on the bridge decks to lower the freezing temperature of water and prevent ice from bonding on a roadway.

TDOT's Sam Credio discusses Operation Freeze in the latest edition of Tucson 12's Behind the Barricades.
