What you need to know about MoDOT's I-70 improvement project

MoDOT contractors will begin working this summer on the first part of the improvement project.

ST. LOUIS — We're on the move and learning more about MoDOT's Improve I-70 project.

The first part of the program concentrates on improvements for the 20-mile stretch of Interstate 70 between U.S. 63 in Columbia and U.S. 54 in Kingdom City.

This summer, Missouri Department of Transportation contractors will beginning building a third lane on the interstate in each direction. The $405 million project is the first of several projects which will widen and improve the I-70 corridor. It's part of $2.8 billion lawmakers approved to build a third lane of I-70 across the state. That's nearly 200 miles from Blue Springs to Wentzville.

"Today's contractor selection marks the beginning of this generational opportunity to improve I-70, which serves as a critical economic east-west corridor across Missouri," Missouri Highways and Transportation Commission Chairman Terry Ecker said. "This is a major challenge to deliver, but our MoDOT team working alongside the private sector partners in engineering and construction will deliver. The selected team, including contractor Millstone Weber and designer Jacobs, competed against one other design-build team."

Along with new concrete pavement on all three lanes between Columbia and Kingdom City, the plan calls for 
wider inside and outside shoulders, and improved interchange designs at the U.S. 63 and U.S. 54 interchanges at I-70.

And here's a big plus for drivers: Throughout construction, two lanes will remain open in both directions during peak hours. 
That's really good news for students and parents making the commute to Mizzou.

"We could not be more humbled and excited," Vice President and Chief Engineer of Milestone Weber Bob Leingang said. "This is a huge deal for everyone who drives this stretch of interstate and uses these interchanges. We will do everything in our power – and then some – to reward the confidence being shown in us to deliver this critical project."

The goal is to finish up that 20 mile stretch by the end of 2027.

MoDOT will host public meetings in central Missouri to share plans about the project, and answer questions. They'll do that before construction gets underway.

We'll keep you posted.
