Bx23 and Q50 buses

The Bx23 and Q50 bus routes constitute a public transit corridor in New York City, running from the Flushing neighborhood in Queens to the Pelham Bay and Co-op City neighborhoods in the Bronx. The Bx23 provides local service in Pelham Bay and Co-op City, while the Q50 provides limited-stop service between Co-op City and subway hubs in Pelham Bay and Flushing. Both routes are city-operated under the MTA Bus Company brand of MTA Regional Bus Operations, and are the only two local routes in the Bronx to operate under the MTA Bus brand, rather than under the MaBSOTA brand that all other Bronx bus routes operate under.

The two routes are the successor to the QBx1 route, privately operated by the Queens Surface Corporation until 2005, when the route was taken over by the MTA. This route ran several confusing service patterns between Co-op City and Pelham Bay, with only select runs continuing to Flushing. In September 2010, to simplify service in the Bronx and to provide full-time service between Queens and the Bronx, the QBx1 was split into the Bx23 and Q50.
