Press Release from the Missouri Department of Transportation
BOONE COUNTY – The eastbound ramps leading from Interstate 70 to the Route Z interchange near Columbia will close to traffic from 7 a.m. to 4 p.m. on Thursday, June 27. The closure will allow the contractor building the Route Z interchange to lay asphalt that will connect the ramps to the new bridge ends.
Motorists can access Rangeline Road by taking the south outer road from Lake of the Woods/St. Charles Road. Drivers will continue to be able to access Route Z by taking the north outer road from Route J in Callaway County.
After the asphalt work is finished, the contractor will begin installing guard rail, which may require the ramps to be closed or restricted to traffic again for a brief time. The dates for any additional closures will be announced once they have been set.
The new interchange is one component of a larger project to improve Route Z in Boone County. In addition to the overpass, the project consists of adding shoulders and resurfacing Route Z from I-70 to St. Charles Road and building a roundabout at the intersection of Route Z and St. Charles Road. The entire project is scheduled to be completed by Aug. 5 in time for the opening of the new Battle High School.
