Arizona Department of Transportation - Highway Maintenance

Report

The Arizona Department of Transportation (ADOT) maintains an expanding state-wide road system with more than 27,000 maintenance lane miles that include all travel lanes, ramps, passing lanes, paved shoulders, and unpaved roads. Money for highway maintenance represents about 10 percent of ADOT’s highway funding, supporting about 250 maintenance activities throughout the State. Arizona’s highway system has mostly smooth and good-quality pavement and was in better condition in 2005 than in 1995. ADOT could better measure and identify annual maintenance work needed to maximize the state highway system’s life, efficiency, appearance, and safety.
