North Outer Road 70 to close at Little Cedar Creek next week…

JEFFERSON CITY, Mo. -The extension of a large culvert under Interstate 70 and the outer roads near mile marker 134.8 will require the closure of a portion of North Outer Road 70 in Boone County, east of Columbia, beginning next week. The closure is expected to continue through February 2026.

As early as the morning of Sept. 25, crews working with the Missouri Department of Transportation, plan to close North Outer Road 70 at Little Cedar Creek (mile marker 134.8 on I-70). There will be no designated detour, but signs located well ahead of the closure will alert motorists to use an alternate route.

Before closing the north outer road at Little Cedar Creek, partial access to Callaway County Route J/Millersburg (Exit 137) will be restored. Pending any weather delays, the Route J ramp onto westbound I-70 could open the night of Sept. 24. The exit ramp from westbound I-70 to Route J will remain closed.

All work is weather-permitting and schedules are 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.
