One lane of I-44 between Conway and Rolla to close overnight starting next week

Core drilling to take place June 30-July 22

JEFFERSON CITY, Mo. – Interstate 44 will narrow nightly for core drilling operations beginning next week. Crews from the Missouri Department of Transportation (MoDOT) will be obtaining core samples at various locations between Conway and Rolla. 

Work is planned overnight, 7 p.m. to 7 a.m., Monday through Friday, June 30 – July 22. Motorist can expect intermittent single-lane closures, both directions. Drivers should expect delays. 

Core drilling allows for a detailed examination of the layers of roadway and supporting geology below the roadway surface. By studying the samples obtained in the cores, the project team can make more informed decisions on design and material elements for future work along I-44. 

All work is weather-permitting, and schedules are subject to change.
