JEFFERSON CITY - Another round of winter weather is expected to affect driving conditions in Missouri tonight and through Saturday. The mix of precipitation could include ice and snow for much of the state. Missouri Department of Transportation crews will be out in full force to treat roads during and after the storm. Motorists are advised to check road conditions before they travel and avoid travel if it all possible especially with potential icy conditions.
MoDOT adjusts its practices to deal differently with each storm and tries to return major roads to near-normal driving conditions as soon as possible after a storm's end. Because MoDOT can't possibly clear all 34,000 miles of state highways immediately after a snowstorm, the department has set priorities for which roads to clear first.
Roads with the highest traffic volumes are plowed or treated first. These roads include interstates and other heavily traveled state routes, which receive ongoing operations in a storm. Lettered and numbered routes with lower traffic volumes are plowed to allow for two-way traffic, with concentration on hills, curves, and intersections. Traffic on these roads may have more snow on them until the higher-volume roads are mostly clear.
As soon as possible after a storm ends, our goal is to return highest traveled routes to mostly clear conditions and to plow and treat the critical areas of hills, curves and intersections on all other routes.
Motorists who need to travel are advised to bring a cell phone and winter survival supplies. Current road conditions are posted on MoDOT's Traveler Information Map at http://traveler.modot.org/map/. The map is also available as an app on your mobile device.
