The Missouri Department of Transportation (MoDOT), alongside team members from Capital Paving & Construction and Burns & McDonnell, hosted a groundbreaking ceremony on Friday, April 3rd to kick off construction for the fifth Improve I-70 project: Boonville to Rocheport.

The project is the fifth in a series of projects that will add a third lane in each direction to I-70 and make other improvements across the state. It is a $104 million design-bid-build project that will add a third lane to I-70 in each direction for the 13-mile section between Missouri Route 5 in Boonville and the Lance Corporal Leon Deraps I-70 Missouri River (Rocheport) Bridge. This project also includes plans to widen two I-70 bridges, one over the Union Pacific Railroad at mile markers 113, and one just west of the Lance Corporal Leon Deraps I-70 Missouri River Bridge at Rocheport.

The project was designed by Burns & McDonnell and was awarded in February 2026 to Capital Paving & Construction. It’s the first project of the Improve I-70 Program to be delivered through the traditional design-bid-build process. By summer 2026, three Improve I-70 Program projects will be underway in central Missouri, between Boonville and Kingdom City. While two lanes of travel will be open along I-70 during peak travel times, motorists can anticipate reduced speed limits and narrowed lanes across the state. Motorists are urged to drive the posted speed limit, eliminate distractions, and allow for extra time.
