During winter weather storms, as well as other weather-related emergencies, TMC staff is on increased alert for potential travel hazards. Using traffic cameras, radar and temperature sensors, along with local agency communication, MDOT’s TMC observes the most traveled highways in the state to ensure the safety and mobility of motorists. Throughout the year, MDOT monitors road and traffic conditions constantly through its Traffic Management Center (TMC). “Crews are fully prepared with all the materials needed to keep highways passable this winter.”
“In north Mississippi, district maintenance crews have trucks and equipment prepared to aid affected roads in the event of a winter storm,” McGrath said. If the roadways are wet, crews spread granular salt, sand or slag over the roads to help vehicles maintain traction. If liquid brine is used too soon, the rain could wash the solution away.
The timing of the precipitation will determine what strategy we use to respond.” “We monitor the weather to see what kind of event we are dealing with, whether it’s liquid or frozen precipitation. “In Mississippi, winter storms are typically associated with rain,” McGrath said.

Sand and slag can also be spread to help improve traction in slushy conditions.ĭrivers are urged to completely scrape windows and windshields free of snow and ice before leaving on a winter’s day for greater visibility on the roadways. If the roads are already wet, granular salt can be applied to help prevent the formation of ice by lowering the freezing point of water. Salt brine can be sprayed on the dry road surfaces to help prevent ice formation on travel lanes. In the past three years, snow and ice operations cost more than $1 million, and MDOT workers logged over 22,000 hours annually addressing winter conditions.ĭifferent materials are used for specific winter weather events. “MDOT crews and personnel are trained and prepared to deploy a range of strategies to keep Mississippi highways open and passable during winter weather events.” “MDOT is committed to safety during the winter season and throughout the year,” said Melinda McGrath, P.E., MDOT Executive Director. Weather conditions can change quickly, and the Mississippi Department of Transportation (MDOT) is prepared to respond to any winter weather and extreme cold events. Despite the mild temperatures, winter officially arrived today (Monday).
