Major projects move forward for SR 189, I-17 and SR 260 to improve commutes, freight travel

A major freight corridor in southern Arizona that moves trucks to and from Mexico for produce and other goods will undergo a full build-out of improvements over the next few years now that the State Transportation Board formally approved the funding for the project.

The board approved the two planned construction phases for State Route 189 at its meeting in Globe on Friday, June 15. Other major expansion projects along key commerce corridors including Interstate 17 and US 93, along with State Route 260, were also approved as part of the annual update to the Arizona Department of Transportation’s Five-Year Transportation Facilities Construction Program.

The 2019-2023 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.

“ADOT’s mission is to provide reliable infrastructure to help move people, goods and services, generate commerce and economic activity, and connect major freight and travel corridors,” ADOT Director John Halikowski said. “This annual process of delivering key projects is a careful balance between assessing priorities and working within our funding constraints.”

The 2019-2023 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 $320 million per year during the next six to 10 years as part of the recently adopted Long-Range Transportation Plan.

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 Sahuarita, 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. The 2019-2023 Five-Year Program, once published next week, can be found at
