In the last five years, the half-cent transportation road maintenance fund has generated between $10 to $15 million annually for road repairs, mitigation for air quality, small projects, and pavement preservation. It is used to fund local projects in unincorporated Pinal County as well as through a population-based formula between the ten incorporated cities and towns. If the fund were to expire, this would lead to transportation cuts for Pinal County and all cities and towns, which would impact transportation investments – especially pavement preservation.
