State Transportation Board Approves Five-Year Construction Program

On Friday, the State Transportation Board approved an annual update to ADOT’s Five-Year Transportation Facilities Construction Program, which includes projects in Greater Arizona and the Maricopa County and Pima County regions. This followed a three-month comment period allowing the public and agencies to provide feedback.

ADOT is able to accelerate some major expansion projects for Greater Arizona because of federal funding increases, grants and state budget appropriations. Key commerce corridors like Interstate 10, State Route 189, US 93 and Interstate 17 will all see capacity improvements over the next five years. In addition, construction of a dust-detection and warning system along I-10 near Picacho Peak will move forward as part of the newly adopted program.

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, 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 2018-2022 Five-Year Program. This list provides an overview and does not include all projects in the Five-Year Program.

Greater Arizona

  • Interstate 10 Widening: State Route 87 to Picacho: This $109 million project (combined with the dust detection and warning system) was accelerated to Fiscal Year 2017 and will continue to construction in FY 18. The highway will be widened to three lanes in each direction and traffic interchanges will be improved.
  • Interstate 10 Safety Improvements: Sunshine Boulevard to Picacho Peak Road (Dust-Detection and Warning System): The construction for this project will be combined with the I-10 widening project from  SR 87 to Picacho ($109 million total for the two projects). The project was accelerated to FY 2017 and will advance to construction in FY 18.
  • Interstate 10: Earley Road to Interstate 8: This $40 million project was accelerated to FY 2018. The project will widen the highway to three lanes in each direction and improve traffic interchanges south of Casa Grande. Upon completion, the entire stretch of I-10 from Casa Grande to Tucson will have been upgraded to a six-lane highway.
  • State Route 189, Nogales to Interstate 19: Total cost is estimated at $69 million for this accelerated design-build project. ADOT is planning to move forward with these improvements along SR 189 to ensure international commerce can efficiently and safely travel between Arizona and Mexico at the Mariposa Port of Entry, one of the busiest land ports in the United States.
  • Interstate 17: Anthem to the Sunset Point Rest Area: This Five-Year Program allows for the design and widening of I-17 in areas between Anthem and Sunset Point, with specific areas and projects still under study.
    • $15 million for design in FY 2019
    • $178 million for widening in FY 2021 and FY 2022 (this includes $128 million from ADOT and $50 million from the Maricopa Association of Governments)
  • US 93: Carrow to Stephens: $35.5 million allocated in FY 2018 advances the widening of this three-mile section of US 93 north of Wikieup. This project is part of ADOT’s commitment to transform all of US 93 to a modern, four-lane divided highway.
  • US 93: “The Gap” Tegner Drive to State Route 89: This project will widen a three-mile stretch of US 93 near Wickenburg to a four-lane divided highway.
  • $5 million for design in FY 2018
  • $41 million for construction in FY 2020
  • US 93/Interstate 40: West Kingman traffic interchange: $5 million for design in FY 2018 and $10 million for right of way in FY 2020 for this new traffic interchange in downtown Kingman. Construction is expected to begin in FY 2024 and is projected to cost $55 million.
  • Two US 93 design projects in FY 2019: $5 million for Cane Springs design (FY 2023 for construction) and $5 million for Big Jim Wash design (FY 2025 for construction). Both of these widening projects are currently in the Six- to 10-Year Development Program.
  • State Route 260: Lion Springs section: $5 million for design in FY 2020. Construction is expected to begin in FY 2023 and is projected to cost $45 million.

Maricopa County region

Many major projects continue to move forward in the Maricopa County region as part of ADOT’s five-year programming process and the recent update to the Maricopa Association of Governments’ 2040 Regional Transportation Plan. This plan includes updated project costs as part of the rebalancing process. Some of the region’s major expansion projects over the next five years are noted below. The complete list of projects can be found in the 2018-2022 Five-Year Program located at azdot.gov/fiveyearprogram.

  • Loop 202 South Mountain Freeway: The 22-mile freeway, which is currently under construction, will provide a long-planned direct link between the East Valley and West Valley and a much-needed alternative to Interstate 10 through downtown Phoenix.
