December Freeze - Tex Dot Response

Posted: Updated:
   Texas Department of Transportation crews have been working round the clock to clear off all roads, bridges, and overpasses during the recent ice storm. The Tex DoT Wichita Falls District is responsible for maintenance of the roads in over nine different counties. 
    Roads in the Tex DoT WFD are divided into four different priorities. Priority One includes I-35, I-44, and US 287. Priority Two includes all Texas Trunk System, National Highway System, and other Priority US Routes. Priority Three includes US, SH& FM with average daily traffic of 1,500 drivers or greater. Last is Priority Four which includes FM roads with average daily traffic of less than 1500.
    TexDot WFD uses four main chemicals and stones used to clear the roads of ice and snow. Magnesium Chloride Liquid also known as "Freezeguard" is used to pre-treat roads. The chemical lays dormant until sleet or snow hits the road activating the chemical. The Magnesium Chloride Crystal is or "Meltdown 20" is what is applied after precipitation has stopped falling. It also helps provide traction the product needs little clean up since it is crushed by tires, activated, and dissipated with water. De-Icing Stone is a light weight man-made aggregate, many confuse it with gravel or sand but the product is actually man-made. DIS helps provide the traction that tires need in the winter weather and melts through the snow and ice. Crushed limestone is the last product that TexDoT uses. While it cost less than DIS it can get blown to the shoulders of the road pretty quick.
    There are over 13 refill stations in the nine County TexDoT WFD that truckers can use to re-fill their supply trucks. Crews will continue to work even after the storm is over sweeping, cleaning roadways and making repairs to any road damages done.
