Arizona’s infrastructure is in satisfactory condition overall, but there is room for improvement, according to a new ranking by the Arizona section of the American Society of Civil Engineers.
The state received a C for its infrastructure, above the nation's overall grade of D+, according to the 2020 report card unveiled Sept. 16.
Arizona's roads have not kept up with the increase in population, according to the report card, which also looked at the state's aviation, bridges, dams, drinking water, levees, rail, transit and wastewater.
While the state’s vehicle traffic has increased 32% from 2000 to 2017, the state’s gas tax is the fifth-lowest in the nation. Arizona’s worst grade on the report card was on its roads, which earned a D+ grade.
