Rebuilding Lake County: Construction season brings another round of major improvements to region

CHICAGO - Rebuild Illinois is continuing to improve mobility, safety and quality of life in Lake County, with the Illinois Department of Transportation delivering multiple major projects this construction season. Made possible by Gov. JB Pritzker's historic capital program, six projects combined represent a total investment of more than $108.8 million, creating and maintaining good-paying jobs throughout the region. ​ ​

"The historic Rebuild Illinois program continues to transform our infrastructure and enhance key economic corridors across the state," said Gov. Pritzker. "Our ambitious capital program is putting Illinoisans to work as we improve regional transportation systems, encourage new economic activity and build a better future for all of Illinois." ​ ​

Of the six major projects in Lake County, two are scheduled to be completed in 2026, with the remaining projects completed over the next two years.

  • U.S. 41 at Illinois 176 (Rockland Road) pump station, storm sewer and ADA improvements. Work began this spring and is anticipated to be completed in 2027. Daily lane closures are in place.
  • U.S. 12 (Rand Road)/Illinois 59 from Illinois 120 to south of Old Rand Road and at Case Road; Illinois 176 from west of Ivanhoe Road to west of Hawley Street channelization, new shoulders and rumble strip installation. Work began in 2025 and is expected to be completed later this fall. Daily lane closures are in place.
  • Sheridan Road over Two Creeks culvert replacements. Work is anticipated to begin in 2027 and be completed in 2028. A detour will be in place with a total closure of Sheridan Road.
  • U.S. 41 north of Illinois 176 to north of the Canadian National railroad new box culvert installation. Work is scheduled to begin later this summer and is expected to be completed this fall. Temporary lane reductions and shifting traffic patterns will be in place.

  • U.S. 41 at Illinois 176 interchange reconstruction. Work is anticipated to begin in 2028 and be completed in 2031. Temporary lane reductions and shifting patterns on U.S. 41 and Illinois 176 will be in place. There also will be temporary road closures and detours on Washington Avenue intersections at Shagbark Road and Skokie Valley Road. ​ ​

"The state of Illinois is continuing its once-in-a-generation investment in our roads, bridges and public infrastructure here in Lake County," said Assistant House Majority Leader Bob Morgan (D-Highwood). "Ensuring residents can get to work, businesses can operate freely and people can travel safely throughout Lake County is not only good for business, but vital to a thriving economy. Families should be able to drive their children to school or head to work knowing that the roads they rely on are safe and dependable. I applaud Gov. Pritzker for his continued commitment to modernizing our infrastructure and making Lake County a safer, better-connected place to live."

"These investments through Rebuild Illinois have a meaningful impact for Lake County, improving the safety, reliability and efficiency of our roads," said Senate Majority Caucus Whip Julie Morrison (D-Lake Forest). "From drainage and storm sewer improvements to major work along U.S. 41 and Illinois 176, these projects will strengthen our transportation infrastructure while supporting our local economy. I'm proud of Illinois' continued investment in infrastructure our communities rely on every day."

"It takes a concerted effort from every agency responsible for our roads to keep our communities moving and our economy strong," said Lake County Board Chair Sandy Hart. "We thank Gov. Pritzker and the state of Illinois for continuing to invest in infrastructure that Lake County residents rely on every day, including some of our most important and heavily traveled roadways. Rebuild Illinois is an essential investment in the future of our transportation network, and we appreciate the continued partnership."

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. ​ ​ ​ ​

"Thanks to Gov. Pritzker's Rebuild Illinois, we are continuing to deliver transformational projects up and down the state," said Illinois Transportation Secretary Gia Biagi. "We look forward to another safe construction season that benefits the region for decades to come." ​ ​

Accomplishments through Year Seven of Rebuild Illinois include $25.6 billion of improvements statewide on 24,498 miles of highways, 959 bridges and 1,475 additional safety improvements.
