Upgrades to the Pennyrile Parkway continue Monday for Interstate 69 through Hopkins, Webster and Henderson Counties.
The Kentucky Transportation Cabinet says traffic will be restricted to one lane for portions of the road between mile marker 61 and 67.
Crews will be digging out and replacing medians with wider crossovers to meet interstate standards.
A work-zone speed limit of 55 miles per hour will also be in effect, along with enhanced enforcement.
