ADOT plans and constructs new freeways, additional lanes and other improvements as part of the Regional Transportation Plan for the Maricopa County region. The primary funding source for regional freeway improvements is a half-cent sales tax approved by county voters in 2004. More information about ADOT projects and the regional plan is available at
