The Bee-Line Bus System, the bus system for Westchester County, operates a network of bus routes throughout Westchester County, serving destinations throughout much of the county and parts of The Bronx in New York City. Even though not used officially by Bee-Line, routes tend to be identified with a "W" prefix (ex: W60), akin to the routing system in New York City. The process is most evident at bus stops in the Bronx and usage by the MTA and New York City government in various media. These routes are listed below.
