 NDOT’s ATM system uses full-color LED signs to provide next-generation, real-time driver information to prepare motorists for upcoming incidents that prompt lane closures or restrictions.  Motorists have the opportunity to react well before they reach the incident, cutting down commute times and greatly reducing the potential for secondary crashes.  

New ATM locations: 


Motorists should use caution while traveling through work zones, and take alternate detour routes, if possible. NDOT works with Waze to inform the public about planned highway restrictions. Construction schedules are subject to change due to weather or other factors. For the latest state highway conditions, visit or call 511 before driving.
