IDOT rebuilds Illinois roads in '25

The Illinois Department of Transportation continued to revitalize and modernize transportation and mobility across the state in 2025.

Made possible by the Rebuild Illinois capital program, projects transformed highways, transit, railroads, airports, waterways and active transportation everywhere Illinois residents call home, creating safer and more reliable travel options while boosting economic opportunity for generations to come.

Passed in 2019, Rebuild Illinois is investing $45 billion in the state's aging infrastructure, creating jobs and building stronger communities. Accomplishments through Year Six include almost $20.8 billion of improvements statewide to 21,309 lane miles of highway, 815 bridges and 1,181 additional safety improvements, ranging from routine maintenance projects and minor resurfacings to extensive interstate and bridge reconstructions.

A 2025 highlight was the October release of the largest multi-year construction program in state history: $50.6 billion over six years, eclipsing the previous record of $41.4 billion in 2024. Covering fiscal years 2026 to 2031, the multi-year program is both comprehensive and multimodal, touching every Illinois county.
