The Improve I-70 Project #2 covering the eastern portion of I-70 between Warrenton and Wentzville was awarded in November 2024. Construction is tentatively set to take place 2025-2028.
Missouri’s FY2024 budget from the General Assembly signed into law by Governor Parson provides $2.8 billion in General Revenue for the costs to build a third lane of I-70 across the state. The program will plan, design, construct, reconstruct, rehabilitate, and add a third lane in each direction on nearly 200 miles of I-70, from Blue Springs to Wentzville.
