Call MoDOT at 1-866-831-6277 to update your MCS account. In some cases, privacy and security procedures require filling out a change form that can only be signed by specific individuals. If that is the case for you, we'll walk you through the process.
Construction & maintenance coming soon
Well before work begins on large projects this spring, you'll see small crews patching potholes, tending to bridges and performing all kinds of work on or near highway lanes.

When you see flashing lights or a sign informing you a crew is ahead, please pay extra attention to the workers and to traffic around you. That will pay off in a smoother drive with fewer incident delays - plus, our coworkers and you are able to get home safely when everyone does their part!

Emphasizing the SAFETY in Safety & Compliance
Brent Hay, a senior transportation enforcement investigator in MCS' Safety & Compliance team was captured by a Sikeston Standard-Democrat photographer as he pushed snow and dropped salt on US 61 near New Madrid, Mo., during a frigid early February snow fight.

Many of the MCS Safety & Compliance staff serve as snowplow operators or in other support roles when weather or other emergencies occur.

Other MCS team members have taken temporary roles in weather emergency, natural disaster recovery and COVID-19 response. We are honored to share our skills and knowledge to lend a helping hand.
