A short segment of Business Loop 70 in Columbia is anticipated to close for two weeks starting in mid-November to complete roundabout construction. Local businesses will remain accessible, but through traffic will need to use an alternate route.
Contractors working with the Missouri Department of Transportation plan to close Business Loop 70 between Hathman Plaza and Eastland Circle from Nov. 12 through Nov. 26. During the closure, all businesses along the stretch will remain accessible.
The new roundabout on Business Loop 70 will ultimately provide direct access to and from eastbound I-70. This closure will enable crews to complete the construction of the roundabout, which will open to traffic on Nov. 26. However, with the new eastbound I-70 lanes under construction, the roundabout is not expected to connect to I-70 until late 2027.
All work is weather-permitting and subject to change.
MoDOT asks all motorists to work with us by buckling up, putting your phone down, obeying all traffic signs, and slowing down and moving over in work zones.
This work is part of the first project in MoDOT’s Statewide Improve I-70 Program, Improve I-70: Columbia to Kingdom City, which will add a third lane of travel in each direction to the 20-mile stretch of I-70 between Columbia) and Kingdom City. This $405 million fixed-cost contract includes new pavement on all three lanes of I-70 and will also make interchange improvements to the I-70 interchanges at U.S. Route 63 and U.S. Route 54.
