Police have already worked at least two deadly crashes along Kentucky roads to begin the Fourth of July holiday weekend.

One person died late Thursday night in Mercer County. Their car ran off Cornishville Road in Harrodsburg. Kentucky State Police say another person was in the vehicle at the time of the crash.

Earlier Thursday night, one person died on Athens-Boonesboro Road in Clark County. Officials say that person died in a single-vehicle crash. The victim hasn't been identified.

Police across the state say they will be out in force throughout the weekend patrolling the roads.

Kentucky State Police are conducting the "Over the Limit. Under Arrest" campaign to increase visibility out on the roads.

AAA expects fewer Americans to hit the roads this Fourth of July because of the economy and high gas prices.
