ST. CHARLES COUNTY – Weather permitting, crews will be closing the Muegge Road bridge over Route 94/364 on Monday, April 10, 2023, after the morning commute.
The bridge is being closed as part of the conversion of the bridge into a partial Diverging Diamond Interchange (DDI). The closure is expected to last until mid-summer 2023.
During construction, Muegge drivers wishing to access eastbound Route 364 can detour west on South Old Highway 94 to Heritage Crossing and proceed east on South St. Peters Parkway to the eastbound Route 364 exit entrance ramp. Westbound Route 364 drivers wishing to access Muegge Road can instead detour to Exit 12 for Heritage Crossing, turn right on Old Highway 94 at the traffic signal and proceed on Old Highway 94 to Muegge Road.
Because Route 364 was originally envisioned to primarily accommodate peak daily commuter traffic, the interchange lacks access for the following traffic movements:
- east and westbound Route 94 to northbound Muegge Road
- southbound Muegge Road to east and westbound Route 94
When completed, newly constructed ramps will provide full access to these roadways that did not exist previously, and there will be a signal located at the north end of the Muegge Road bridge over Route 94 for the redesigned traffic movements at the interchange.
This bridge 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
