With the possibility of snow and rain in the forecast throughout the Mardi Gras holiday weekend, the Louisiana Department of Transportation and Development (DOTD) announced today that department staff is prepared to deal with winter weather.

Maintenance forces will be on standby to apply sand and salt over any affected bridges and roadways, to remove fallen trees from the roadway, and to close any roads as needed.

Interim Secretary Sherri LeBas urges motorists to take the threat of winter weather seriously. “In the event of adverse weather conditions, the department will strive to maintain access to Louisiana’s highways and interstates; however, we encourage the motoring public to avoid traveling during snow and ice, if at all possible,” said LeBas.

During winter weather conditions, the best thing motorists can do is drive slowly and carefully, and avoid driving while distracted. Always allow for extra driving time, reduce speeds when visibility is low, and make sure there is plenty of room between vehicles. Also, look out for black ice, which can form on bridges, overpasses, off-ramps and in shady spots. As always, DOTD reminds motorists to buckle up and refrain from drinking and driving.

Citizens can get the latest updates on real-time traffic and road conditions by using the 511 Traveler Information System simply by dialing 511 from their telephone and saying the route or region about which they are seeking information. Travelers can also access this information by visiting the 511 Traveler Information Web site at www.511la.org.

Motorists can also obtain information regarding road closures by contacting DOTD’s Customer Service Center at 1-877-4LA-DOTD (1-877-452-3683). The center is open 7:30 a.m.- 5 p.m. Monday through Friday.

GOHSEP is in contact with those parishes where sleet, snow, and potential icing of Louisiana roadways is forecasted in parts of the state.

“While we are anticipating some potentially dangerous winter weather, we urge everyone to pay attention to their local news and weather forecasts and avoid driving in icy conditions. If you haven’t already done so, this is the time to have some extra supplies on hand in the event of a power outage due to icy conditions,” says GOHSEP Director Mark Cooper. “Please prepare your homes, bring your pets inside and check on the elderly and disabled. Also, take special precaution when using space heaters. Keep combustibles at least three feet away from the heater.”

GOHSEP is also coordinating efforts with other state agencies such as the Department of Health and Hospitals (DHH), Department of Social Services (DSS) and the Department of Transportation and Development (DOTD).

Department of Agriculture and Forestry:

Issuing advisories for owners of livestock

Department of Health and Hospitals:

Assessing the number of hospital beds available to prepare for cold-related injuries or illness
