Improve I-70 Projects

Missouri’s FY2024 budget from the General Assembly and signed into law by Governor Parson provides General Revenue for the costs to plan, design, construct, reconstruct, rehabilitate and repair three lanes in each direction on nearly 200 miles of Interstate 70, from Blue Springs to Wentzville. 

MoDOT has been working on the best plan to be efficient and innovative in how the 200 miles of I-70 will be delivered. As of May 2025, the Improve I-70 individual project limits have been updated and now include eight total project segments across the state. The nearly 200 miles will be broken into various contracts that will be awarded throughout 2029. Total completion of the corridor is anticipated by the end of 2030.
