“Today’s groundbreaking is a momentous occasion not only because we’re kicking off our historic Improve I-70 project, but it’s a culmination of the bold infrastructure initiatives we’ve prioritized since day one,” Parson said. “I-70 is one of Missouri’s oldest and most vital corridors. The safety and economic prosperity of Missourians depend on an interstate that grows along with the state and nation. Expanding I-70 to six lanes has been talked about in Jefferson City for decades, but our administration, in working with Senator Lincoln Hough and the General Assembly, is taking action and getting it done. We could not be more proud that the work we’re commemorating here ... will continue serving Missourians for generations to come.”
Missouri’s FY2024 budget from the General Assembly, signed into law by Parson, provides $2.8 billion in General Revenue for the costs to build a third lane in each direction on nearly 200 miles of I-70, from Blue Springs to Wentzville. This first project, Improve I-70: Columbia to Kingdom City, is a $405 million fixed-cost contract that will add an additional lane to I-70 in each direction between U.S. Route 63 in Columbia and Route 54 in Kingdom City. The project also incorporates $123 million in previously programmed Missouri Department of Transportation projects to improve the I-70 interchanges at both Route 63 and Route 54.
“Thank you to the Governor and the General Assembly for their support of this generational investment of I-70 for Missouri’s future,” said W. Dustin Boatwright, Missouri Highways and Transportation Commission Chairman. “[The] event in Columbia is just the first step to transform I-70 across the state. ... We are actively working on the next bid package, and we look forward to completion of the entire I-70 corridor by late 2030.”
The planned improvements for Project #1: Columbia to Kingdom City from the design-build contractor Millstone Weber and its designer Jacobs Inc. also include new concrete pavement on all three lanes of I-70 in each direction of the project. Additionally, throughout construction two lanes of travel will be available in both directions of I-70 during peak hours. Construction of this project is set to begin in July 2024 with an anticipated completion in late 2027.
