There's no escaping construction delays on the Tri-State Tollway (I-294) next week with interchange projects cropping up in three strategic locations that will affect about 112,650 drivers daily.
Ramp repairs will start at the Tri-State and Belvidere Road near Grayslake, Lake Street near Elmhurst and I-55 near the Hinsdale Oasis.

The elaborate interchange where I-55 meets I-294 is the most problematic, accommodating 80,000 vehicles a day with eight ramps to be rebuilt. Workers also will fix four ramps at Belvidere Road and one at Lake Street.
The work includes tearing down and reconstructing the concrete ramps plus improving lighting and drainage.
• The Belvidere interchange will leave ramps open but traffic shifts will occur along with some lane closures on the road. Shoulder closures on the westbound I-294 exit ramp to eastbound Belvidere Road and eastbound I-294 entrance ramp from eastbound Belvidere will start next week. Traffic will be shifted to the left through July, when it will switch to the right. The remaining ramps will be reconstructed later in the year.
• The Lake Street interchange involves rebuilding the entrance ramp to the northbound I-294. Shoulder closures start next week, with traffic shifting to the left first. Work should finish by fall.
• The I-55 and Tri-State interchange includes repairs to the exit ramps linking I-294 with I-55, Joliet Road and Wolf Road, plus ramps taking drivers from the northbound Tri-State to the Hinsdale Oasis. Next week, off-peak ramp lane closures will occur and traffic will eventually be shifted to the left. A temporary ramp will accommodate drivers heading to the Hinsdale Oasis from northbound I-294.
