  COLUMBIA — Extensive construction work on the interchange at Route Z off Interstate 70 is scheduled to begin Tuesday and will keep the overpass closed until early August. 

The Missouri Department of Transportation project will start at mile marker 133 and include three key components:

  • Resurfacing Route Z and adding shoulders from I-70 to St. Charles Road;
  • Building a roundabout at the intersection of Route Z and St. Charles Road;
  • Replacing the Route Z bridge over I-70.

During construction, motorists will be detoured around the overpass. Access to Route Z will be via the north outer road from Route J in Callaway County. Rangeline Road  will be accessible by taking the south outer road from Lake of the Woods/St. Charles Road exit.

All work on I-70 involving lane closures will be scheduled at night.

The Route Z overpass is scheduled to be demolished Wednesday and Thursday. I-70 will be closed temporarily after rush hour, from 7 p.m. to 5 a.m. both days. Single-lane traffic will be diverted to exit ramps and back onto the interstate. 

"Just take it easy through there, follow the signs and everything will be fine," Resident Engineer Charles Sullivan said. 

The project, costing approximately $2.3 million, has been funded through a collaboration between MoDOT and Boone County. The county's funding is approximately 33 percent of the amount, according to MoDOT.

Route Z improvements are targeted to help with the increased traffic expected with the opening of the new Battle High School. It is designed to increase highway capacity and improve the connection at Route Z and St. Charles Road.

More information about this project can be found at or by calling 1-888-ASK-MoDOT (275-6636).
