As many as 62 methamphetamine labs were found and two men were charged after an investigation about 12 miles south of London, according to the Laurel County sheriff's department.
The operation began Wednesday night and continued into early Thursday morning at a home on Paris Karr Road, according to the department.
Sheriff John Root said David Heard, 41, of Richmond, and Scotty Lewis, 37, of Corbin are charged with 74 counts of first-offense manufacturing of methamphetamine and first-degree trafficking in a controlled substance. They were taken to the Laurel County jail.
Paris Karr Road was shut down for some time as a safety precaution while the meth equipment was being dismantled, the sheriff's office said. The road reopened about 5:30 a.m. Thursday, according to deputies.
