PHOENIX — The Arizona State Transportation Board has officially approved an updated five-year Transportation Facilities Construction Program, which allocates $11.5 billion for infrastructure projects aimed at improving safety, capacity, and efficiency across the state’s highway and transportation systems.
The plan, approved during the board’s June 20 meeting in Payson, focuses heavily on pavement preservation, bridge repairs and upgrades, and modernization of key facilities including intersections, ports of entry, and rest stops.
Funding for the ambitious program will come from a mix of federal, state, and local sources, including gas and diesel fuel taxes, the Arizona vehicle license tax, and county-specific sales taxes approved by voters in Maricopa and Pima counties.
ADOT to Prioritize Pavement and Bridge Improvements
According to the Arizona Department of Transportation (ADOT), $2.4 billion of the total funding will be invested over the next five years to maintain and upgrade pavement and bridges on the state highway system.
Additional improvements will feature the installation of smart technologies, new signals and signage, and the modernization of rest areas to enhance safety and traffic flow.
ADOT said the effort reflects a strategic approach to both preserve aging infrastructure and support the state’s growing transportation demands.
