Eastbound I-70 access to exits 144 and 148 to be limited for several months

Ramp closures set to begin tonight, Aug. 7

JEFFERSON CITY, Mo. - With westbound Interstate traffic returned to the westbound lanes between Callaway County Route M/Hatton (mile marker 144) to U.S. Route 54/Kingdom City (mile marker 148), eastbound traffic is set to shift into the newly paved median tonight, Aug. 7. With this, eastbound access to exits 144 and 148 will be limited for several months.

For construction crews working with the Missouri Department of Transportation to start reconstructing the existing eastbound lanes, eastbound traffic will shift onto the lanes constructed in the median, separated from westbound traffic with a temporary concrete barrier wall. Eastbound I-70 will be narrowed to 10-foot lanes and speeds reduced to 55 mph. Those traveling eastbound will be unable to change lanes between mile markers 144-146 and 148-149. This configuration, narrowing, and speed reduction will be in place for several months.

Additionally, the ramp from Exit 144 to eastbound I-70 will be closed throughout the traffic shift - both westbound ramps are open. The ramp from eastbound I-70 to Exit 148 will also be closed for approximately two months. Motorists must use an alternate route during the ramp closures.

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.
