HANNIBAL - Route TT in St. Charles and Warren County has been closed due to winter road conditions. MoDOT and the Missouri State Highway Patrol closed the road to traffic because of its curvy and hilly terrain. Road conditions will continue to be a concern over the next 24 hours, and motorists are discouraged from unnecessary travel. Road conditions and closures can be found on MoDOT's online traveler map at www.modot.org, which is also available as a smartphone app. Please drive carefully if you have to go, always wear a seat belt and give driving your full attention.
