Rebuilding Southern Illinois: Interstate, roundabout projects highlight another historic construction season
Gov. Pritzker’s capital program modernizing infrastructure throughout region and Illinois
CARBONDALE – As part of one of its busiest construction seasons ever, the Illinois Department of Transportation is delivering several major projects in Southern Illinois, fueled by Gov. JB Pritzker’s historic, bipartisan Rebuild Illinois capital program. Thirteen projects combined represent a total investment of nearly $534 million, improving safety and mobility while sustaining and creating good-paying jobs throughout the region.
“Through Rebuild Illinois, we are making good on our promise to restore and transform our state’s infrastructure while promoting economic growth,” said Gov. Pritzker. “This summer, IDOT will continue to build on years of progress by undertaking construction projects that will create safer roads and bridges and provide jobs across the state. Through these projects, we are demonstrating what government is supposed to do and that’s investing in the people and communities we serve.”

“The state’s Rebuild Illinois capital plan continues to invest in the strong, reliable infrastructure our residents deserve,” said Pinckneyville Mayor and President of the Southern Illinois Mayors Association Robert Spencer. “I’m thankful to Gov. Pritzker and the IDOT team for prioritizing these southern Illinois transportation projects, ensuring safety and modernization in our region.”
Passed in 2019, Rebuild Illinois is investing a total of $33.2 billion over six years into the state’s aging transportation system, creating jobs and promoting economic growth. Rebuild Illinois is not only the largest capital program in state history, but also the first that touches all modes of transportation: roads and bridges, transit, waterways, freight and passenger rail, aviation, and bicycle and pedestrian accommodations.
“Rebuild Illinois continues to reshape transportation, creating economic opportunity, improving mobility and enhancing quality of life in every corner of the state,” said Illinois Transportation Secretary Gia Biagi. “Remember: If you are traveling anywhere in Illinois this summer, you will be traveling through work zones. When you see orange, slow down and save lives.”
Accomplishments through March 31 of Rebuild Illinois include approximately $14.8 billion of improvements statewide on 6,078 miles of highways, 629 bridges and 895 additional safety improvements.
