Overnight, work crews were busy on the main runway of Blue Grass Airport. Workers are preparing the main runway for center lights to be installed on a later day.
Crews were only allowed to do some minor work to prepare the runway for the main construction.
Major construction can't take place until after runway inspections are completed next week.
The runways are supposed to remain similar to the condition they were on the day of the crash of Flight 5191.
