Arizona Transportation Board approves five-year construction program update
The Arizona State Transportation Board approved the 2027-2031 Five-Year Transportation Facilities Construction Program on June 19, 2026. The program emphasizes pavement and bridge improvements, as well as the expansion of several key highways. These projects will improve highway safety, efficiency and functionality, such as intersection improvements, updates to ports of entry and rest areas, smart technologies and new signals, signs and shoulders.
The five-year program features several projects that increase the capacity or expansion of highways throughout Arizona, including widening SR 260 east of Payson, known as the Lion Springs segment, widening U.S. 93 at Big Jim Wash between Wickenburg and Wikieup, constructing the James Ranch Road between SR 80 and the new Douglas Land Port of Entry and improving I-17 from Dugas Road at milepost 269 to milepost 275.
In Maricopa County, the five-year program lists projects planned in conjunction with the Maricopa Association of Governments, including beginning construction of the center segment of SR 30, which runs from Loop 303 to Loop 202, also known as the South Mountain Freeway, widening and making other improvements to the Mini-Stack Interchange east of downtown Phoenix at I-10/Loop 202/SR 51 and widening U.S. 60 between Ellsworth and Meridian roads.
