KY highway 453 in Livingston County is closed until further notice at the 11.5 mile point which is between Cutoff Road and Cothron Road.
Livingston County authorities say a culvert has collapsed beneath the highway.
Repairs will need to be made before the KY 453 can be reopened.
The Cutoff Road can be used as a detour route between Smithland and Grand Rivers until repairs are made.
