Motorists in St. Charles County are set to face a lane closure starting next week as the Missouri Department of Transportation (MoDOT) begins work on expanding Interstate 64. The eastbound I-64 ramp from Route K will be reduced to one lane from June 2, as part of a larger project to widen the interstate. This lane reduction is slated to last through July, intending to eventually ease traffic by adding a third lane in each direction between Route K and the I-70/I-64 interchange. MoDOT emphasizes that all scheduled work is subject to change depending on the weather.
The Improve I-70 Warrenton to Wentzville Project is designed to expand the capacity of I-70 between Warrenton and Wentzville. Awarded in November 2024, the construction is tentatively scheduled to begin in 2025 and continue through 2028. This initiative is part of Missouri’s strategic effort to efficiently and safely manage anticipated growth in traffic volumes.
Funding for this major infrastructure endeavor comes from the state's FY2024 budget, which was legalized into law by Governor Parson. The $2.8 billion provided from the General Revenue is dedicated to the construction of additional lanes on nearly 200 miles of I-70, stretching from Blue Springs to Wentzville.
The project is expected to provide both economic and logistical benefits by reducing congestion and enhancing the efficiency of one of Missouri’s key transportation corridors. Motorists are advised to stay alert in construction zones and consider alternate routes to avoid potential delays during the project timeline.
