ST. LOUIS – Drivers using the westbound Route 364 exit ramp to eastbound Route 94 in St. Charles County could experience delays when the exit ramp closes for reconstruction starting Monday, December 20, weather permitting.
The ramp closes after morning rush and will remain closed through summer 2022. Access to the Muegge Road exit ramp from westbound Route 364 will remain open during this phase of the reconstruction work.
Drivers wishing to access eastbound Route 94 from westbound Route 364 can detour west on Route 364 to the North St. Peters Parkway exit, cross over onto Heritage Crossing and then turn left onto South St. Peters Parkway and eastbound Route 364 to Route 94.
On the I-270 North Project in north St. Louis County, crews have now converted Pershall between Elizabeth Avenue and Knollway Drive to one-way eastbound traffic. This change allows for the continuing reconstruction of Pershall Road to proceed.
