Biden's infrastructure law completes its five-year $550 billion appropriations window

FY2026 is the final year of the IIJA's original five-year $550B appropriations window. Formula funds for highways, bridges, transit, water, and broadband complete their authorized disbursement cycle. Remaining unobligated discretionary funds for EV charging, climate resilience, and grid modernization are subject to ongoing Trump administration litigation. After FY2026, infrastructure funding reverts to pre-IIJA baseline levels unless Congress reauthorizes.
