ST. CHARLES COUNTY – Drivers using westbound Route 94 to access eastbound Route 364 in St. Charles County will be detoured starting Monday, March 13, weather permitting. The ramp is scheduled to be closed until mid-summer.  

Crews will close the westbound Route 94 ramp after the morning rush as part of the conversion of the Muegge Road bridge into a Diverging Diamond Interchange over Route 94/364. 

Drivers will be detoured by continuing on westbound Route 94/364 and exiting at Heritage Crossing/North St. Peters Parkway, then turning around eastbound on South St. Peters Parkway to continue to eastbound Route 364. 

This ramp closure is part of the Route 94/364/Muegge Road improvements. For more on the interchange improvements, visit the project website: https://www.modot.org/interchangeimprovements
