ADOT plans and constructs new freeways, additional lanes and other improvements in the Phoenix area as part of the Regional Transportation Plan for the Maricopa County region.

Most improvement projects are currently funded in part by Proposition 400, a dedicated sales tax approved by Maricopa County voters in 2004. Voters also approved Proposition 479 in November 2024, extending the existing half-cent tax to fund future transportation projects in the Phoenix region.

Reminder: Real-time highway conditions are available on ADOT's Arizona Traveler Information site at AZ511.gov, the az511 app (download for Apple or Android devices) or by calling 511.
