A new report has found some progress has been made to improve the nation's aging infrastructure, but a lot more needs to be done.

This week, the American Society of Civil Engineers released its 2025 Report Card for America's Infrastructure. It gives the nation an overall grade of "C," up from a "C-minus" in 2021.

Kristina Swallow, assistant city manager for the City of Tucson, credited the Inflation Reduction Act and Bipartisan Infrastructure Law, even as both have been targeted by the Trump administration. She said more improvements will require more funding.

"We feel it," Swallow pointed out. "If you get stuck in traffic or if you have somebody who is injured while they're riding their bike or walking to work, you know that the system isn't necessarily working the way it should be. We want to help make sure that when industry, local, state and federal governments invest in infrastructure, that they're doing it wisely."

The report showed just over half of Arizona roads are in either poor or fair condition. It noted $12 billion is needed to improve drinking water systems and $4 billion to upgrade wastewater systems in the state.

Swallow pointed out bridges are among the brighter spots in Arizona's scores, with fewer than 2 percent of the more than 8,500 bridges in the state in poor condition. She stressed the Bipartisan Infrastructure Law was essential to support maintenance.

"While Arizona has generally, I think, some of the better bridges in the nation, that additional bridge investment on a national level really helped some of the other states address some of their poor and failing bridges," Swallow observed. "As well as start to look at some of the 'fair' bridges and bring them back up into good repair."

Community expansion and climate change have increased demand for repairs. Swallow added some voters have noticed and supported initiatives at the ballot box in recent years.

"In Tucson, they've voted three times to invest in roadway infrastructure, in connections and greenways and in parks," Swallow reported. "Because they recognize that the community members in Tucson need to have roads that meet their needs."

And even if current federal infrastructure funding were to remain the same, the report added there would still be a $3.7 trillion gap over the next decade.
