ST. LOUIS – With more possible winter weather projected for Friday night, motorists should plan ahead and give themselves extra time to travel this weekend as there may be accumulating snow. Drivers are encouraged to use extra caution, anticipate slower drive times, and consult road conditions before traveling.

If you are on the roadway, please watch for our crews on the road and stay well away from the back of the trucks. They will be moving slowly, especially if they are plowing, but they will often be treating the roadway behind them at the same time.

Check all current Missouri road conditions on the Traveler Information Map at traveler.modot.org, or through MoDOT’s smartphone app, available for free for iPhone and Android phones. Also find road conditions and warnings by following MoDOT on Facebook and Twitter or by calling 888-ASK-MODOT (888-275-6636) to speak with a customer service representative 24 hours a day, seven days a week, 365 days a year.
