The B100 is a bus route in the New York City borough of Brooklyn. Originally operated by Command Bus Company, the bus route is now operated by MTA Bus Company, running between Midwood and Mill Basin.

Route Description

The B100 bus route first starts at East 16th Street and Quentin Road near the Kings Highway station through a loop. Then it turns east onto Quentin Road. By the end of the intersection, it continues southeast through Gerritsen Avenue until it merges northeast via Filmore Avenue. After that, slightly turning to Avenue T, Mill Avenue, and Avenue U. Lastly, it turns down south spirally, and ending through a loop at National Drive and Mill Avenue during a drop-off and 56th Drive and Strickland Avenue during a pick-up.^[2][3]

History

It began on February 3, 1960 by Pioneer Bus Company. It was extended from Bassett Avenue to 56th Drive (then called McMullen Drive) in August 1960.

It was later operated by Command Bus Company starting October 22, 1979, due to a long strike at Pioneer Bus Company.

On December 5, 2005 the MTA Bus Company took over the routes from Command Bus Company, including the B100 bus.

Bus redesign

On December 1, 2022, the MTA released a draft redesign of the Brooklyn bus network. As part of the redesign, the B100 service will be rerouted to use Avenue R instead of Quentin Road, replacing the B2, which will be eliminated.^{[4] [5]}
