Ongoing Lane Closures and Restrictions

Both directions of Interstate 70 at the Cave Springs and Zumbehl interchanges are reduced and barrier wall has been added between the median and shoulders underneath each interchange. The reduction in lane widths will remain in place on I-70 through mid-2023.

Lanes on northbound and southbound Cave Springs will be narrowed and shifted to the east and a barrier wall will separate traffic from the active work zone. 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.
