Muegge Road Interchange Improvements Underway

Posted on February 17, 2022 at 3:07 PM by County Council

While there has been significant growth in the western parts of St. Charles County, especially, District 7 and its surrounding areas in the eastern portion of the county have kept up with the busyness and excitement of business additions and residential offerings. 

With this growth has come the need for improvements to our roads systems to help alleviate traffic congestion and provide easier access to main thoroughfares for commuters. I am pleased with the addition of the slip ramps at Heritage Crossing that were completed ahead of schedule in 2021, but another project currently under construction will add more direct access options for drivers travelling between Route 364, Highway 94 and Hemsath and Muegge roads.

The Muegge Road interchange improvements include on/off ramps to Route 364 and Highway 94. This new interchange accommodates travel in both directions to and from these routes, creating safer, more efficient access. The project will replace the current interchange with a diverging diamond interchange, along with a traffic signal at the north end of the existing bridge over Highway 94. Additionally, the signal at Portwest Drive and Highway 94 will be removed, an eastbound lane between the interchange and Zumbehl Road will be added, as well as a westbound lane from Pralle Lane to Portwest Drive.

The total cost of construction is estimated at $22 million, $7.5 million of which comes from the County’s ½-cent Transportation Sales Tax. The City of St. Charles is contributing $6.3 million; the Missouri Department of Transportation (MoDOT), $6.2 million.
