 "Louisville-Jefferson County Government" (Louisville Metro) and "Lexington-Fayette Urban County Government" (Lexington Metro) are unique in that their city councils and county Fiscal Court structures have been merged into a single entity with a single chief executive, the Metro Mayor and Urban County Mayor, respectively.Although the counties still exist as subdivisions of the state, in reference the names Louisville and Lexington are used to refer to the entire area coextensive with the former cities and counties.Somewhat incongruously, when entering Lexington-Fayette the highway signs read "Fayette County" while most signs leading into Louisville-Jefferson simply read "Welcome to Louisville Metro".
