JEFFERSON CITY, Mo. – The Improve I-70: Boonville to Rocheport project is set to get underway next week with nighttime lane closures. Motorists should slow down and pay attention to roadway signing directing them through the nightly work zone.
On March 9, construction crews working with the Missouri Department of Transportation plan to begin shoulder work along both eastbound and westbound Interstate 70 from Missouri Route 5 in Boonville to the Lance Corporal Leon Deraps I-70 Missouri River (Rocheport) Bridge. Shoulder work will require nighttime lane closures during this first phase of work. One lane in each direction may be closed at night between 7 p.m. and 6 a.m. with an 11-foot width restriction in place.
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.
Improve I-70: Boonville to Rocheport 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.
Improve I-70: Boonville to Rocheport was designed by Burns & McDonnell and awarded in February 2026 to Capital Paving and Construction. It is the first project of the Improve I-70 Program to be delivered through the traditional design-bid-build process. In design-bid-build procurement, designs are completed before the plans are provided to contractors for bid. The lowest responsive bidder wins the construction contract.
Missouri’s FY2024 budget, approved through the state legislative process and signed into law by the governor, provides $2.8 billion in General Revenue 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.
