Because of the holiday weekend, highway construction in the state will be put on hold so that all interstates and expressways can remain open. That includes work zones on I-65 and the Watterson Expressway.Spokesperson Andrea Clifford says the Kentucky Department of Transportation does not allow lane or ramp closures on holiday weekends due to the high volume of traffic. Beginning at five am this morning and ending on Tuesday at five am, work zones must leave all lanes open. Clifford says there are some barriers in place at work sites and those will remain in place, but motorists will be able to navigate all Kentucky highways.
