It was a longer commute to work for some people in Johnson County Tuesday morning. Large rocks fell on to Kentucky 321 just after 8:30 covering both lanes.
Road crews quickly cleared one lane for traffic to pass, but had to wait for more help to get the larger rocks off the road.
Jeff Kelly with the Transportation Cabinet says, "With the big stuff like that, we have to get a contractor to come in and bust it up small enough so we can load it up and haul it in the trucks."
One driver said he watched the rock fall from his rear view mirror, and others say these dangerous falls are too common along 3-21.
Leo Fell drives along KY 321 every day and says, "You have to keep it in your mind. You just remember that it's there and it can happen. People really shouldn't stop under the cliffs, you never know when a rock is going to fall."
Officials say this stretch of Kentucky 321 is on the Transportation Cabinet's six year plan for repairs. The project will cost more than 2 million dollars.
Transportation crews say falls like this one are due to changes in moisture, soil, and climate.
