MoDOT to restrict section of Veterans Memorial Parkway to temporary one-way traffic

ST. CHARLES COUNTY – The Missouri Department of Transportation will temporarily restrict Westbound Veterans Memorial Parkway between Cave Springs Boulevard and Mexico Road to one-way traffic. The temporary conversion begins overnight Wednesday, May 10, 2023, weather permitting. A new overpass is being constructed to allow traffic on Veterans Memorial Parkway to go under Cave Springs Road without stopping at a traffic signal.

This temporary configuration is expected to last for the majority of 2023.

“This is a temporary situation, not a planned permanent conversion from two-way to one-way outer road traffic,” said Nick Gibbons, MoDOT Project Director. “This temporary conversion allows our contractor to construct the new segment of Veterans Memorial Parkway that will go under Cave Springs Road, which will restore connectivity to this portion of the outer road system and improve traffic operations and safety of the overall corridor. We urge motorists to consider alternate routes or allow for extra time to get to their destination during this outer road work.”

During construction, Veterans Memorial Parkway traffic can only go in the eastbound direction (no westbound traffic) between Cave Springs Boulevard and Mexico Road.

Once construction is completed, this section of Veterans Memorial Parkway will be returned back to the normal two-way traffic configuration.

This construction is part of the I-70 Cave Springs to Fairgrounds Design-Build Project.

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.
