Transportation Programming Budget

Primary funding sources for the Five-Year Transportation Facilities Construction Program are derived from federal highway trust funds, transportation excise tax monies and state highway user revenues. Bond proceeds are used as needed to attain a balance between critical construction requirements and revenue availability. Funding for the current Five-Year Transportation Facilities Construction Program totals $6.1 billion.

The programming of both state and federal monies is guided by numerous stipulations regarding the use of monies. The end result is a categorization of projects by program funding. The major categories are:

Over the five-year program period, the Maricopa County urban freeway system will receive nearly $2.9 billion of the expected funds. The primary source of this program is the transportation excise tax assessed by voters in Maricopa County. Another portion of this program will be financed by 37% ADOT Discretionary funds and federal funds dedicated to the MAG area.

The Five-Year Aviation Program totals $922.9 million. Federal, state and local funds are the primary sources for financing airport construction projects. Federal monies are derived mainly from taxes on airline tickets and are distributed by the Federal Aviation Administration to local airports through the National Airport Improvement Act. State funds come mainly from flight properly tax, lieu taxes on aircraft and aviation fuel taxes.

Federal grant monies will finance $817.0 million of the program while the state share is around $67.9 million. Local sponsors contribute another $37.9 million.

To meet these required deadlines, work on the program update must begin in the late summer or early fall of each year. The following chart identifies a typical schedule for the program update.
