Region 2, District 2: New entrance ramps to northbound and southbound Interstate 39 opened July 24 as part of the reconstruction of the I-39 and U.S. 20/Harrison Avenue interchange in Cherry Valley from a cloverleaf to a diverging-diamond design. Work will now focus on constructing the exit ramps to U.S. 20/Harrison Avenue from I-39. 

The $44.2 million interchange project is part of a larger $302 million, multiyear project made possible by Gov. JB Pritzker’s Rebuild Illinois capital program to improve I-39 between the U.S. 20/Harrison Avenue interchange and Blackhawk Road in Cherry Valley and Rockford. Most of the interchange project is scheduled to be complete by the end of the year, with some final touch-up work to be completed in spring 2026. 

Region 4, District 6: A 3-mile resurfacing project is underway on Veterans Parkway (Illinois 4) from Prairie Crossing to Greenbriar Drive, in Springfield, began July 14. Other work includes sidewalk ramp improvements. 

The nearly $9 million project is expected to be completed by the end of August.
