Much needed traffic relief is on the way for those who travel Highway 94 in the City of St. Charles. Improvements currently are being constructed and include adding a third lane in each direction on Route 94 and interchange improvements at Route 364/Route 94/Muegge Road. When complete in Summer 2023, the project will increase mobility, reduce travel times, reduce crashes, increase capacity, and improve local access to and from Routes 94 and 364. 

“This is an important project that was made possible due to a partnership between St. Charles County, St. Charles City, and MoDOT,” says St. Charles County Executive Steve Ehlmann. “Because of that partnership, we are not only able to make needed improvements to the state’s infrastructure, but this project will also provide new ramps for better access to Muegge Road. These improvements were an unfunded local priority that otherwise would not have been constructed without the efforts of the County and city to secure the funding needed through a competitive state cost-share program.”  

Fixing the traffic jam on Route 94 and improving access to Muegge Road has been a priority of District 7 Councilman John White for many years. The project is in his district. 

“This is another example of how the County’s ½-cent Transportation Sales Tax helps us improve infrastructure,” White says. “I am so pleased for the residents and business owners in my district that this project is in the works and that there will be better access to homes and businesses. While there are detours and traffic delays now, the end result will improve safety and mobility as the county continues to grow.”  

Councilman White has been a champion for improvements in this area since the opening of Route 364 in 2001, which converted segments of Route 94 to a freeway know as Route 364. That was a much-needed project due to congestion, but improvements in traffic flow hurt local access. White’s efforts to restore local access resulted in the recently constructed and now opened new ramps to and from Route 364 to Heritage Crossing, and reconstruction of the Muegge Road interchange. 

The total cost of construction for the Muegge Road project 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; MoDOT, $6.2 million.
