MoDOT helps keep traffic flowing around the region 24/7. The Transportation Management Center is an important part of that -- dispatching maintenance, emergency response, or repair crews to incidents on state roads.
news and events
Since 1987, Missouri's Adopt-A-Highway program has involved volunteers across the state working together to clean up Missouri. Currently, more than 5,300 groups and 50,000 volunteers in the program are focused on making Missouri’s roadsides cleaner and more attractive for our residents and visitors. More than 6,400 miles of roadway have been adopted.
Adopters perform about $1 million a year in litter cleanup and beautification efforts. Every area kept free of litter by adopters allows MoDOT to devote resources to other much-needed tasks.
MoDOT Map App
The MoDOT Traveler Information Map shows current work zones, incidents and weather-related road conditions on state maintained roads in Missouri. Issues that have an impact on travel are loaded automatically. This app should not be the only tool used when making a decision based on drivng conditions.
