SPRINGFIELD, Ill. (WCIA) — Six major construction projects are either underway or scheduled to begin in Sangamon County this summer.

The upcoming construction season is expected to be one of the busiest ever, IDOT officials said, with Sangamon County among those seeing closures and traffic adjustments. The six projects that will take place there, all under the ongoing Rebuild Illinois project, will represent a state investment of nearly $103 million to improve safety and mobility.

“Rebuild Illinois is revitalizing communities and neighborhoods by investing in projects and people in the Springfield area and throughout the state,” Governor Pritzker said in a statement. “Through the largest capital program in state history, IDOT will be delivering improvements to build a more resilient, accessible and equitable system of transportation for generations to come, while creating jobs and enhancing local quality of life.”

12 construction projects underway, starting soon in Macon Co.

Three projects are already underway with another three starting this summer. Five will be complete before the year is over while one will stretch into 2026. Those projects are:

  • 10th Street railroad tracks at Madison and Jefferson Streets in Springfield

    • Underpasses and double tracking

    • Started in 2023, expected to be complete this summer
