JEFFERSON CITY, Mo. - An upcoming traffic shift on Interstate 70 between mile markers 144 and 149 will restrict westbound access to Callaway County Route M/Hatton for several months. Beginning overnight May 12, weather-permitting, motorists will need to use an alternate route.

Construction crews working with the Missouri Department of Transportation have completed building two new lanes of I-70 in the existing median between Route M and U.S. Route 54 in Kingdom City. Crews now plan to start reconstructing the existing westbound lanes. Overnight May 12, westbound traffic to be shifted onto the newly constructed lanes, separated from eastbound traffic with a temporary concrete barrier wall.

During the traffic shift, westbound I-70 will be narrowed to 10-foot lanes and speeds reduced to 55 mph. Those traveling westbound will be unable to change lanes between mile markers 144-146 and mile markers 148-149. Additionally, the ramp from westbound I-70 to Exit 144 from will be closed for several months. As an alternate route, motorists can take Exit 148 (Kingdom City) and use the north Outer Road 70 to Route M.
