The Indiana Department of Transportation has permitted coring operations during overnight hours on Interstate 65 in Bartholomew County.

INDOT officials say that Earth Explorations crews will be onsite beginning Sunday night taking pavement and soil core samples from all I-65 lanes, one lane at a time, from State Road 46 at Columbus north to a terminus beyond U.S. Highway 31. Speed limits will be reduced to 55 mph between 9 p.m. and 6 a.m. while workers are present.

INDOT officials anticipate nighttime operations continuing for approximately one week.
