The14th Street Crosstown Line is apublic transit line inManhattan,New York City, running primarily along14th Street fromChelsea or theWest Village to theLower East Side. Originally astreetcar line, it is now theM14bus route, operated by theNew York City Transit Authority under the MaBSTOA subsidiary. The line's two variants, theM14A SBS andM14D SBS, useAvenue A andAvenue D respectively from 14th Street south to the Lower East Side.

Both M14 services share the 14th Street Crosstown corridor between 9th Avenue on the West Side and Avenue A on the Lower East Side. The "A" and "D" designations refer to the north–south streets used by each service within the Lower East Side (Avenue A and Avenue D respectively).^[3][5]

West of 9th Avenue, the M14A SBS turns south alongHudson Street, terminating atBleecker Street atAbingdon Square Park. The M14D SBS meanwhile, travels north toChelsea Piers, servingHudson River Park and theChelsea Market. Until Select Bus Service was implemented, the M14A SBS followed this route during the overnight hours.^[3][5] This was changed to operate to Abingdon Square at all times.^[6] At the east end of the corridor, the M14A SBS turns south at Avenue A (which becomesEssex Street south ofHouston Street), then east alongGrand Street to theFDR Drive on theEast River coastline. The M14D SBS travels along Avenue C, East 10th Street, then south along Avenue D (becoming Columbia Street) to Houston Street, turning east onto Houston Street and running along FDR Drive to Delancey Street.^[3][5]

During weekday rush hours, some M14 SBS buses makeshort turn runs, resulting in some westbound M14 buses terminating at eitherUnion Square orEighth Avenue, and some eastbound M14 buses terminating atFirst Avenue. These trips may be signed as just the M14, without any letter suffix.^[3]

The M14A/D SBS routes supplement the14th Street Line (L train), which runs from Eighth Avenue and continues intoBrooklyn.^[3][5]

Two XD60s: one local-wrapped 2017 (6105) on the Abingdon Square-bound M14A in August 2018 before implementation (top), and one SBS-wrapped 2019 (6152) on the Chelsea Piers-bound M14D in June 2024 after implementation (bottom), both at West 14th Street/8th Avenue.

The tracks were built by several companies and pieced together by theMetropolitan Street Railway by 1899. TheBleecker Street and Fulton Ferry Railroad built the 14th Street tracks west of9th Avenue, theCentral Crosstown Railroad built from 9th Avenue toUnion Square, and theForty-Second Street and Grand Street Ferry Railroad built from Union Square toAvenue A and south on Avenue A. The Metropolitan Crosstown built a short connection at Union Square to connect the two halves, and tracks north on11th Avenue to theWest 23rd Street Ferry.

When theWilliamsburg Bridge opened in 1904, 14th Street cars were rerouted to use the bridge (running east onDelancey Street from theone-way pair ofClinton Street northbound andEssex Street southbound), running as the14th Street-Williamsburg Bridge Line until 1911. Buses were substituted for streetcars by theNew York City Omnibus Corporation on April 20, 1936.

Avenue D service was added on January 28, 1951, initially running from Broadway along 14th Street, Avenue D and Columbia Street to Stanton Street, and returning on Cannon Street and Houston Street.^[7]

In 1956, New York City Omnibus Corporation becameFifth Avenue Coach Lines; theManhattan and Bronx Surface Transit Operating Authority (MaBSTOA) subsidiary of theNew York City Transit Authority took over operations in 1962.^[8]

The route was once operated by the now defunct Hudson Pier Depot and was known only as the M14. When the depot was taken over by the Quill depot, it was separated into three lines, the M14A, M14C and M14D. Following theSeptember 11 attacks, security measures at the Consolidated Edison power plant were tightened, and the block of East 14th Street between Avenue C and Avenue D was closed to the public. Service was consolidated on the Avenue C and Avenue D branches of the M14, with bus service running along Avenue C, East 10th Street, and Avenue D. In May 2002, the MTA announced plans to consolidate the two routes to improve service, and make operations simpler.^[9] Eventually it was decided since the route ran primarily on Avenue D the route would be renamed M14D.

From 2004 to 2006, the M14C briefly returned running down Avenue C to Houston Street, then turning east towards Avenue D/Columbia Street and resuming the normal route. This new route began running late and caused confusion with the M21 on Avenue C and eventually service returned to its current state as the M14A and M14D. Afterward, Avenue C was temporarily served by theM21 bus, but since 2010, it has been served by theM9 bus.

Two XD60s: one 2017 (6117) on the Grand Street-bound M14A SBS, and one 2019 (6224) on the Delancey Street-bound M14D SBS, at 14th Street/6th Avenue in Chelsea/Greenwich Village, Manhattan in January 2022.

In April 2019, aSelect Bus Service line was planned to run along 14th Street to provide alternate service during the originalL train shutdown plan. Service was expected to operate from Ninth Avenue to Avenue C, then turn north along Avenue C to20th Street, where there would be a ferry transfer.^[10][11] This route was to be another branch supplementing the existing M14A/D designation, but the existing lines would not be converted to Select Bus Service. To facilitate bus trips on the M14 corridor, the14th Street busway would be implemented, turning parts of 14th Street into a bus-only street during rush hours.^[12] The Select Bus Service route was to be implemented by January 6, 2019, three months before the tunnel was set to shut down. It was to initially run with five stops in each direction between First Avenue/14th Street and 10th Avenue/14th Street. Local service on the M14A and M14D would be retained with minor modifications.^[13] One or two weeks before the tunnel would originally close, the M14 SBS was to be extended toStuyvesant Cove. The M14A/D local and the M14 SBS would be able to serve a combined 84,000 passengers every hour, with a bus every two minutes during rush hours. During late night hours, the M14 SBS would be replaced by theL14 SBS route to theBedford Avenue station in Brooklyn.^[14][15] After the 14th Street Tunnel work was completed, some version of M14 SBS service would continue operating.^[16]

On January 4, 2019, Governor Andrew Cuomo announced that the L train shutdown would be modified. An alternate plan of weekend and late-night construction would be executed instead, therefore putting the initial M14 SBS plan in limbo.^[17][18] New York City Transit later announced that it still planned to implement SBS along the corridor, and continued to work with the DOT on a plan for permanent service. The preliminary plan was to convert both the M14A and M14D routes into SBS routes.^[19] On March 6, 2019, the NYCDOT met with elected officials and revealed plans to implement Select Bus Service on both the M14A and the M14D in June 2019, with an accelerated timeline to provide an alternative to L service. The implementation of bus lanes on the branches on the Lower East Side was to be implemented later on. Bus stops on each branch would be spaced out to speed up service. The M14A's terminal loop throughAbingdon Square was to be implemented on a 9-month trial due to difficulty of bus operations there, as well as complaints of buses laying over in the Abingdon Square area. If the terminal was eliminated during or after the trial, service would be extended to Tenth Avenue. As of May 2022, the M14A continues to serve Abingdon Square at all times.^[6] Bus lanes would either make use of the busway layout intended for the Tunnel shutdown or would consist of standard bus lanes.^[20][21]

In April 2019, the busway was added back to the plan.^{[22][23][24][25]} SBS was later pushed back to July 1, 2019.^[26][27] However, due to a lawsuit, the busway was not implemented as scheduled,^[28][29] and after another delay that August,^[30][31] went into effect on October 3, 2019.^[32][33] The busway was so successful on its first day that M14 buses had to be slowed down in order to keep from running ahead of their posted schedules.^[34] In December 2019, the M14A/D SBS were the launch routes for the MTA's new battery-electricNew FlyerXcelsior XE60 buses.^[35]
