The ASCE Arizona Section announced the release of the 2026 Report Card for Arizona’s Infrastructure, assigning 11 categories of infrastructure a cumulative grade of ‘C’. This grade on par with the national infrastructure grade of ‘C’ in the 2025 Report Card for America’s Infrastructure. While this grade is ahead of many around the country and hits the national average, a ‘C’ is not an acceptable status for systems that play such a vital role in keeping communities safe and businesses operational.
The 2026 grades are:
| Grade | Categories |
| B+ | Bridges |
| B- | Aviation |
| C | Energy, Levees, Rail, Transit, Wastewater |
| C- | Dams, Drinking Water, Stormwater |
| D+ | Roads |
Arizona is experiencing some of the most rapid population growth and business development in the nation and, currently, the state’s relatively young infrastructure networks are supporting this growth. Eight of the 11 categories in the report have higher grades than in the national report card and several categories boast strong condition ratings, particularly in the transportation sector.
While these are positive trends leading to a stronger economy and more robust communities, the additional activity means infrastructure capacities must be expanded, and current systems will have greater maintenance needs. Increasingly frequent extreme weather events are also adding strain to some of the state’s aging assets.
The 2026 Report Card for Arizona’s Infrastructure provides insight needed to start conversations and ignite action to improve the 2026 grades and, as a result, the Grand Canyon State’s future by:
- Ensuring sustained funding for Arizona’s most critical systems;
- Prioritizing existing asset maintenance in future infrastructure planning;
- Utilizing new innovations to bring much needed updates to the state’s infrastructure, such as different delivery methods, new materials, and smart technology;
- Incorporating resilience and adaptation in the design and maintenance of infrastructure assets to keep up with population growth; and
- Investing and modernizing assets in rural communities to maintain safe infrastructure for its entire life cycle.
