The Arizona Department of Transportation says it will be working with $350 million less as it maps out construction projects for the next five years.

The department says the decreased funding is due to stagnant revenue from gas and vehicle license taxes, and declining federal aid. Director John Halikowski says some tough decisions will have to be made about how to spend limited dollars.

The public can begin submitting comments on three scenarios Friday. One focuses on preserving the state’s highway system, another focuses on major projects, and the third is a combination of those two.

Public hearings are planned in Phoenix, Tucson and Flagstaff.

The State Transportation Board is expected to adopt a final plan to cover 2014 to 2018 at its June meeting in Pinetop-Lakeside.
