Cooper County Route Z will narrow to one lane at the bridge over Interstate 70 this Saturday, April 18, for bridge boring operations as part of Improve I-70: Concordia to Boonville.

Construction crews working with the Missouri Department of Transportation will flag traffic through the single-lane work zone, which is scheduled to be in place from 7 a.m. to 5 p.m., Saturday. Bridge borings allows for a detailed examination of the geology below the surface. By studying the samples obtained, the program team can make more informed decisions on design and material elements regarding bridge structures as they work to expand I-70 to three lanes in each direction across Missouri.

This work is part of Improve I-70: Concordia to Boonville, the eighth project in MoDOT’s Statewide Improve I-70 Program. Construction on this section of I-70 is scheduled to begin in 2027

All work is weather-permitting, and schedules are subject to change. Motorists are asked to use caution and pay extra attention through the work zone.
