JEFFERSON CITY, Mo. – The intersection of Conley Road and Business Loop 70 in Columbia is set to close starting at the end of March to build a roundabout. Local businesses will remain accessible, but through traffic will need to use an alternate route.
Starting on March 23, contractors working with the Missouri Department of Transportation plan to close Conley Road at the intersection with Business Loop 70 for 60 days. During the closure, the business entrances on either side of the intersection will remain open and accessible. The roundabout is expected to be open to all traffic by the end of May.
When complete, the roundabout will provide a safer and more efficient intersection. Compared to a signalized intersection, roundabouts have fewer conflict points, which, along with slower speeds and calmer traffic, can translate into as much as 76 percent fewer crashes and fewer crash-related injuries.
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.
Missouri’s FY2024 budget, approved through the state legislative process and 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.
