Transportation Programming

Current Five-Year Program

State Transportation Board approves 2020-2024 Five-Year Construction Program
I-17, I-10 to undergo major widening and improvement projects in the next five years.

Two major interstate corridors for passenger and freight traffic will be widened and improved during the next five years, now that the State Transportation Board formally approved the funding for the two projects.

With the board’s approval, the planned construction of additional lanes along Interstate 17 between Anthem and Sunset Point, along with the study, design and construction of additional lanes along Interstate 10 between Phoenix and Casa Grande, will now move forward.

The two projects recently received additional funding in the state budget approved by state lawmakers and signed by Governor Doug Ducey. Both projects are also able to advance through ADOT’s partnership with the Maricopa Association of Governments, the regional planning agency that has committed some of the funds for the I-17 and I-10 improvements. 

The board made its decision at its meeting in Pinetop-Lakeside today. Other expansion, preservation and modernization projects along state highways were also approved as part of the annual update to the Arizona Department of Transportation’s Five-Year Transportation Facilities Construction Program.

The 2020-2024 Five-Year Program includes projects in Greater Arizona and the Maricopa County and Pima County regions. Today’s final approval of the program followed a three-month comment period allowing the public and agencies to provide feedback.

“The I-17 and I-10 expansion projects are clearly our two biggest transportation priorities around the state,” ADOT Director John Halikowski said. “We need more lanes to move traffic along these two major travel and commerce corridors while still focusing on safety improvements. Deciding on and delivering key projects that meet the state’s transportation needs is a careful balance between assessing priorities and working within our funding constraints.”

The 2020-2024 Five-Year Program also reaches the department's goal of allocating at least $260 million per year for preservation of bridges and highways throughout the state highway system. In addition, ADOT has proposed increasing the amount of preservation funding to $350 million per year during the next six to 10 years.

Preservation projects include repaving highways, filling potholes, extending the life cycle of existing pavement, and repairing or reconstructing bridges.

The State Transportation Board’s approval of the Five-Year Program followed a call for public comment in March and three public hearings in Tucson, Flagstaff and Phoenix. In general, major projects begin as part of the agency’s long-range visioning process, move into a 20-year plan and a six- to 10-year development program and then become part of the Five-Year Program, which is developed by working closely with local planning organizations and community leaders to identify projects that are ready to build or design.

Funding for the Five-Year Program is generated by the users of transportation services, primarily through gasoline and diesel fuel taxes and the vehicle license tax. Both the Maricopa and Pima county regions have independent revenue streams established through voter-approved sales tax increases that allow for more expansion projects to take place.

The following is a list of major projects for Greater Arizona, the Maricopa Association of Governments (MAG) region and the Pima Association of Governments (PAG) region during the next five years. This list provides an overview and does not include all projects in the program.
