ADOT – Drivers covered nearly 67 billion miles on Arizona roads in 2016, the state’s fifth consecutive annual increase, according to a Federal Highway Administration estimate.
Part of a Traffic Volume Trends report estimating a record 3.2 trillion miles driven on U.S. public roads last year, the Arizona figure demonstrates the importance of maintaining and improving the state’s transportation system, said John Halikowski, director of the Arizona Department of Transportation.
“Highways are Key Commerce Corridors that drive economic growth and jobs,” Halikowski said. “A well-built and well-maintained transportation system positions this growing state to capitalize on its proximity to major markets in California and Texas as well as south of the border.”

ADOT maintains all state and federal routes in Arizona, including six interstate highways.
The estimated number of vehicle miles traveled in Arizona in 2016 – 66.86 billion – represented an increase of more than 1.8 billion miles from 2015, or 2.8 percent. Since 2011, the number of miles navigated by Arizona drivers has increased by 7.28 billion, or 12 percent.
The 13-state West, including Arizona, had the greatest increase in travel compared with 2015, according to the Federal Highway Administration’s report.
ADOT reports vehicle miles traveled for the previous year each June. The agency’s figures also show a steady increase in recent years.
