ST. CHARLES COUNTY – Drivers traveling on the Cave Springs interchange over Interstate 70 will notice lane shifts starting the week of September 26. Crews will begin preparations for the lane conversion Monday, September 26 from 7 p.m. to 5 a.m., weather permitting.

Lanes on northbound and southbound Cave Springs will be narrowed and shifted to the east starting Tuesday night, September 27. A barrier wall will separate traffic from the active work zone. All lanes of Cave Springs will remain open.

In addition to the lane shift, one of the two left turn lanes from eastbound I-70 to northbound Cave Springs will be closed. Motorists will still be able to make a left turn from the remaining open turn lane.

Both the lane shift and the exit lane closure will remain in place until spring 2023. This work is part of construction of the new structure that will take Veterans Memorial Parkway underneath Cave Springs.

The Cave Springs and Zumbehl interchanges are being converted into single point urban interchanges (SPUI) for the I-70 Cave Springs to Fairgrounds Design-Build Project. As construction on this project progresses, both interchanges will remain open to drivers.
