MoDOT to close Interstate 70/Cave Springs for 15-minute closures to set girders overnight Dec. 7-8

ST. CHARLES COUNTY – Drivers on Interstate 70 at Cave Springs may experience temporary delays overnight Wednesday, December 7 and Thursday, December 8. Crews will be placing girders over I-70 from 9 p.m. until 5 a.m.

Motorists can expect a two-lane closure approaching the bridge construction and then 15-minute intermittent full closures of the interstate while girders are swung into place.

Crews will start setting the girders on westbound I-70 at Cave Springs on Wednesday, December 7. Then, crews will place girders on eastbound I-70 at Cave Springs the following night, Thursday, December 8. All work is weather permitting.

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.
