The state Transportation Cabinet has asked its geotechnical branch to look at the site of a fallen boulder that caused a two-vehicle crash Tuesday night in Garrard County.
The recommendations for the stretch of road won't be known until the evaluation is performed, a spokeswoman for the Transportation Cabinet wrote Wednesday in an email message. She did not indicate when the evaluation would be performed or whether it would involve a temporary closing of the road.
The huge rock fell from a cliff onto the southbound lane of U.S. 27 just south of the bridge that spans the Kentucky River between Garrard and Jessamine counties.
A green car hit the rock head-on and then a white pickup rear-ended the car, firefighters on the scene said Tuesday night. The Garrard County Sheriff's Office did not release the names and conditions of the two people injured.
Never miss a local story.
The same stretch of U.S. 27 saw smaller rock slides earlier this year.
In January, the Garrard County Sheriff's Office reported that three vehicles had four flattened tires after motorists drove over a small rock slide in the southbound lanes. A state maintenance crew removed the rubble with shovels, brooms and a backhoe.
Then, in February, a rock slide landed in the northbound lanes of U.S. 27. At least one truck was damaged.
The rocks are falling from a man-made cut where the road descends near the Kentucky River bridge.
The seasonal process of freezes and thaws typically causes rock slides, but it's not known what caused Tuesday night's fall. The rock and debris were moved to the shoulder.
