It is very common for UDOT Maintenance crews to coordinate on activities such as winter operations, maintenance construction projects, and or emergency situations with adjoining States. Coordination and frequent communication between these states ensures that maintenance projects and activities will not adversely affect the adjoining states, especially during times of high traffic or inclement weather. It may also become necessary in the times of emergencies to join forces to be able to ensure there is safe passage between all adjoining states.
Below are links to the adjoining states home web pages, and their district or area contact info for their Maintenance Divisions:
