The Illinois Department of Transportation continued to revitalize and modernize transportation and mobility across the state in 2025, the department said in its year-end report.

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.

“From launching the largest infrastructure program in state history to spearheading transformational projects, Illinois is making landmark investments in our present and future – creating good-paying jobs and paving the way toward an Illinois that is built to last,” said Gov. ​ JB Pritzker. “Whether it’s on a repaved road, over a repaired bridge, or in a brand-new bike lane, IDOT is working to get you where you’re going smoothly and safely while supporting community revitalization in every corner of the state.”

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.

“The past year was another landmark one for investing in people and communities up and down Illinois,” said Illinois Transportation Secretary Gia Biagi. “The projects and initiatives today are making our state a better place to raise a family, build a career and do business for tomorrow.”
