Single-lane restrictions will take place on Gulf Lab Road in Harmar through next week so crews can perform drilling operations for a future project, PennDOT said.
The restrictions will be between Old Route 910 and William Pitt Way.
They will take place weekdays from 8 a.m. to 4 p.m. They will begin Thursday and last through Tuesday.
Crews from Armstrong Drilling, Inc. will perform the drilling operations in preparation for a future project.
Traffic will be controlled by flaggers.
