Work-zone safety is important not only to protect those who build and maintain our highways, but also to protect motorists. Preventable rear-end collisions are the most common type of work-zone crash. Simple things such as slowing down, obeying signs and flaggers, and preparing for lane restrictions go a long way to keep everyone safe.
Expect the unexpected. Normal speed limits may be reduced, traffic lanes may be restricted and people may be working on or near the road.
Slow down! Obey work zone speed limits.
Keep a safe distance. Maintain two car lengths between you and the car in front of you as well.
Pay attention. Observe the posted signs.
Obey road crew flaggers. A flagger has the same authority as a regulatory sign. You can be cited for disobeying a flagger's directions.Check road conditions before you travel. Schedule enough time to drive safely and check for traffic information by calling 511 or by logging on to az511.gov.

Engineering analysis fees must be received by the Class C Permits Office prior to engineering analysis being performed.
Loads over 250,000 lbs, over axle weight, or in excess of the posted bridge weights are analyzed by the ADOT Bridge Preservation Services.
Engineering analysis may take up to two weeks. Certified weights are required. Failure to provide the correct weights may require a second analysis to be performed by the ADOT Bridge Preservation Services and will incur a new analysis fee.
