Part of I-64 in Montgomery County, that was closed for several hours Sunday night because of an accident, is now re-opened.

Kentucky State Police say a tractor trailer rear-ended a pick up truck hauling a horse trailer.

Police say they driver of the tractor trailer told them he did not see the horse trailer while coming up over a rise in the road. It does not appear the lights on the horse trailer were functioning at the time of the accident.

There were four horses in the trailer, and two were injured. Neither driver was injured in the crash.
