The Bee-Line Bus System, branded on the buses in lowercase as the bee-line system, is a bus system serving Westchester County, New York. The system is owned by the county's Department of Public Works and Transportation. It was founded on May 1, 1978, by the then Westchester County Department of Transportation to consolidate the bus system with thirteen private bus companies and has been given control over the buses, fare structure, routes, and services. By the 1980s, the bus system had an identity problem in who was providing the service. On May 19, 1987, WCDOT officially named the bus service "The Bee-Line System" with a 'bee-in-flight' mascot. The Westchester County Department of Public Works and Transportation currently contracts out to two private bus companies to provide service in Westchester County and the surrounding counties: Yonkers-based Liberty Lines Transit, Inc., the main company that either bought out or obtained franchises from the other twelve bus companies over the years, operates buses on all but three bus routes; and Cortlandt Manor-based P.T.L.A. Enterprise, Inc., a small company that operates buses on routes 16, 18, and 31.
