List of bus routes in Manhattan

Several companies, most prominently the Metropolitan Transportation Authority (MTA), operate a number of bus routes in Manhattan, New York, United States. Many of them are the direct descendants of streetcar lines (see list of streetcar lines in Manhattan).

Companies

Presently, the New York City Transit Authority and its subsidiary Manhattan and Bronx Surface Transit Operating Authority operate most local buses in Manhattan. The Roosevelt Island Operating Corporation operates the Roosevelt Island Red Bus Service.

The first bus company in Manhattan was the Fifth Avenue Coach Company, which began operating the Fifth Avenue Line (now the M1 route) in 1886. When New York Railways began abandoning several streetcar lines in 1919, the replacement bus routes (including the current M21 and M22 routes) were picked up by the New York City Department of Plant and Structures (DP&S). The DP&S began operating several other buses (including the current M79 and M96 routes) in 1921. All of these but the M21 were acquired by Green Bus Lines in 1933; Green transferred several of these to the Comprehensive Omnibus Corporation in 1935.

The New York City Omnibus Corporation began operating replacement routes for New York Railways lines abandoned in 1936, and acquired the remaining Green routes. They also acquired the Madison Avenue Coach Company (former New York and Harlem Railroad lines), Eighth Avenue Coach Corporation (former Eighth and Ninth Avenue Railways lines), and in 1942 the Triangle Bus Corporation (current M21 route).

In 1936, the NYCO and Fifth Avenue were placed under common ownership. The two were merged directly by 1956, when the NYCO acquired the Surface Transportation Corporation (which had operated former Third Avenue Railway routes since 1941), and changed its name to Fifth Avenue Coach Lines. After a strike, the entire Fifth Avenue system was transferred to the newly formed Manhattan and Bronx Surface Transit Operating Authority on March 22, 1962.^[1][2][3]

In 1933, two related companies began to operate routes: the Comprehensive Omnibus Corporation gained several Green Bus Lines routes (including the current M22, M27, and M50 routes), and the East Side Omnibus Corporation started operating former Second Avenue Railroad routes (including the current M15 and M31 routes). The Comprehensive also started the current M66 route that year, and in 1948 the New York City Board of Transportation acquired the Comprehensive and East Side routes, transferred to the New York City Transit Authority in 1953. The M9 route came from the Avenue B and East Broadway Transit Company in 1980, which had begun operating replacement routes for the Dry Dock, East Broadway and Battery Railroad lines in 1932.

History of the current Manhattan bus routes

Routes M1 to M23

Route	History
M1	Fifth Avenue Coach Company began operating its Fifth Avenue Line bus in 1886 Madison Avenue Coach Company bus replaced New York and Harlem Railroad's Fourth and Madison Avenues Line streetcar on February 1, 1935. In Fiscal Year 1963, the route was modified in Midtown to improve traffic.[53] The two routes were combined as a one-way pair on January 14, 1966. Due to a budget crisis, overnight service, weekend service south of 106th Street, and weekday South Ferry service were discontinued and service was rerouted to match the M2 on June 27, 2010.[54] Weekend service south of 106th Street was restored on January 6, 2013.[55] Service was extended back down to Grand Street from 8th Street on September 3, 2017; service will eventually be re-extended to Worth Street.[56][57]
M2	Fifth Avenue Coach Company began operating this bus route on February 23, 1901. Northbound buses were moved to Madison Avenue on January 14, 1966, and the route was renumbered to the 2A.[58] Renumbered from 2A to M2 on July 1, 1974.[59] Limited-stop service began on October 14, 1991, replacing local service between 7 a.m. and 7 p.m.[60] On June 30, 2024 the M2 stop on Audubon Ave at W 165th St will be discontinued, was redirected to Amsterdam Ave [61]
M3	Fifth Avenue Coach Company began operating this bus route on February 23, 1901. Northbound buses were moved to Madison Avenue on January 14, 1966. Northbound service were rerouted away from University Place and 9th Street on June 27, 2010, due to a budget crisis.[54] Service was rerouted from St. Nicholas Avenue between 155th Street and 163rd Street in September 2010. On June 30,2024 the M3 stop terminal will relocated on St Nicholas Ave at W 192nd St. [62]
M4	Fifth Avenue Coach Company began operating this bus route on August 5, 1900. Northbound buses were moved to Madison Avenue on January 14, 1966. In 1983, service was rerouted via Broadway between West 110th Street and West 135th Street due to the reconstruction of the Riverside Drive viaduct. The viaduct reopened in 1987. In October 1987, the MTA board voted to make the change permanent at the next available pick. It was made permanent because the land-use along Broadway was more conducive to transit use than the land-use along Riverside Drive. The route along Broadway was slower, but was shorter by two blocks.[63] Southbound buses were rerouted via West 37th Street instead of via West 34th Street between Fifth Avenue and Seventh Avenue due to new turning restrictions on November 1, 2015.[64] On July 4, 2018, the M4's terminal was moved from Penn Station to East 32nd Street and Fifth Avenue to accommodate sidewalk widening on 32nd Street.[65] On June 30, 2024 the northbound M4 stop on E 32nd St at 5th Ave will be relocated to Madison Ave at E 32nd St. The stop on E 32nd St at 5th Ave will be drop-off only.[66]
M5	Fifth Avenue Coach Company began operating this bus route on August 5, 1900. Northbound buses were moved to Sixth Avenue between Houston Street and 57th Street on January 14, 1966. In 1983, service was rerouted via Broadway between West 120th Street and West 135th Street due to the reconstruction of the Riverside Drive viaduct. The viaduct reopened in 1987. In October 1987, the MTA board voted to restore its old route via Riverside Drive. The restoration of service via this route reduced end-to-end travel time on the route. In addition, peak-hour service running via Riverside Drive between West 135th Street and West 157th Street was rerouted via Broadway. Four southbound trips had used this route during the a.m. rush hour and three northbound trips had used it during the p.m. rush hour. Only an average of 12 passengers boarded along this portion of the route because service along this section was infrequent and unreliable. These changes were made at the next available pick.[63] On September 10, 1989, buses were rerouted from 57th Street to 59th Street to reduce travel time.[67] In September 1996, three changes were made to M5 service. All service began making limited stops on weekdays between 6:30 a.m. and 6:30 p.m. southbound and between 7 a.m. and 7 p.m. northbound. This change reduced running time by 15 minutes, significantly reducing operating costs, and was expected to boost ridership and reduce overcrowding at the 72nd Street subway station. In addition, M5 service was rerouted off Riverside Drive and onto Broadway between West 135th Street and West 120th Street. Along this stretch there were only three bus stops as the Riverside Drive Viaduct is elevated above street level. Rerouting the M5 was intended to improve passengers heading to and from this section of Broadway. The reroute was expected to slow service by four minutes as Broadway was more congested than Riverside Drive. Finally, the span of northbound service was increased in the morning, with the first bus leaving Houston Street at 6 a.m. instead of at 7 a.m. This change was made because the service pattern was confusing to riders and because service further up the line started later than most other Manhattan bus routes during rush hour. The first northbound bus did not arrive at 65th Street until about 8 a.m.[68] On June 27, 2010, the route was extended from West Houston Street/Broadway to South Ferry to replace the M6 due to a budget crisis[54] The route was cut back to Sixth Avenue and West 31st Street on January 8, 2017, with the South Ferry to Midtown portion of the route split into the M55 route.[69][70]
M7	New York City Omnibus Corporation buses route (M22 - 7) replaced New York Railways' Columbus Avenue Line streetcar on March 25, 1936. Northbound buses were moved to Amsterdam Avenue on December 6, 1951, and to Sixth Avenue on March 10, 1957, north of 34th Street and November 10, 1963, south of 34th Street. The southern terminus of the route was shifted to Sixth Avenue in 2009. Southbound buses were rerouted from Broadway to run on Seventh Avenue in 2009. Limited-stop service was introduced on February 22, 1993, but was eliminated before August 1994.[71][72][73]
M8	New York City Omnibus Corporation bus route (M16 - 13) replaced New York Railways' Eighth Street Crosstown Line streetcar on March 3, 1936. Designated the M13 until c. 1993, when the route was renumbered the M8. Weekend and overnight service was discontinued on June 27, 2010, due to budget crisis.[54] Weekend service was restored on April 6, 2014.[74][75]
M9	Avenue B and East Broadway Transit Company bus (M9) replaced Dry Dock, East Broadway and Battery Railroad's Avenue B Line streetcar on July 30, 1932. Original terminals were Battery Park City and 14th Street–Union Square station. Northern end ran via Avenue B. Southern end originally ran via Park Row to Batter Park City. Service was rerouted via Water Street and the South Ferry–Whitehall Street station after the September 11 Attacks when Park Row was closed to vehicular traffic. On June 27, 2010, the route was rerouted from Avenue B to Avenue C to 23rd Street due to a budget crisis. On the same date, the route was rerouted back to Park Row to replace the M15 to CIty Hall.[54] The route was extended north to 29th Street via First Avenue from 23rd Street and south to Battery Park City from City Hall on January 6, 2013.[54][76]
M10	Eighth Avenue Coach Corporation bus route (M41 – soon became NYCO's 10) replaced Eighth and Ninth Avenues Railway's Eighth Avenue Line streetcar on November 12, 1935. New York City Omnibus Corporation bus route (M24 - 8/9) replaced New York Railways' Seventh Avenue Line streetcar on March 6, 1936. Routes combined as a one-way pair on June 6, 1954, and kept the number 10 continued south to Abingdon Square, Spring Street and Battery Park City until 1999. In Fiscal Year 1963, the route was modified due to the conversion of some two-way streets to one-way streets. Service began running north along Hudson Street and south along Seventh Avenue.[53] Originally had limited-stop service in the peak direction until September 10, 1995. South of Penn Station split off into route M20 on January 16, 2000.[77] Service south of Columbus Circle ended June 27, 2010, due to budget crisis. On April 3, 2011, service was extended two blocks south.[78]
M11	Eighth Avenue Coach Corporation bus route (M42 – soon became NYCO's 11) replaced Eighth and Ninth Avenues Railway's Ninth Avenue Line streetcar on November 12, 1935. Northbound buses were moved to Tenth Avenue on November 6, 1948. Southbound buses were moved to Columbus Avenue on December 6, 1951. On June 26, 1994, the route was extended along 135th Street and Riverside Drive to Riverbank State Park.[79]
M12	New bus route created on August 31, 2014, to provide north–south service along Manhattan's west side.[80]
M14A M14D (M14)	New York City Omnibus Corporation bus route (M17 - 14) replaced New York Railways' 14th Street Crosstown Line streetcar on April 20, 1936. Avenue D service added on January 28, 1951; initially from Broadway along 14th Street, Avenue D and Columbia Street to Stanton Street, and returning on Cannon Street and Houston Street.[81] In Fiscal Year 1963, the route was extended at the request of residents along the route.[53] Originally known as the M14 with service also along Avenue C. M14 split off into M14A, M14C, and M14D. M14C variant merged with M14D variant after 2001, but returned from 2004 to 2006 before being discontinued again. Route was converted to be a Select Bus Service route on July 1, 2019.
M15	East Side Omnibus Corporation bus route (M15) replaced Second Avenue Railroad's Second Avenue Line streetcar and began running route (M13) on First Avenue on June 26, 1933. The routes were combined as a one-way pair on June 4, 1951, and kept the number M15. Limited-stop service began on September 13, 1976, with buses making only 15 stops, spaced every eight blocks, between 126th Street and Houston Street, saving riders up to 23 minutes. Limited-stop service ran every six minutes on weekdays, heading southbound in the morning, between 7:12 and 9:21 a.m., and northbound in the afternoon, between 4:12 and 6:11 p.m.[82] These buses were identified by signs on the lower right side of the windshield.[83] This was one of the first routes in NYC to begin limited service, the other being the Q44A (later Q46). In January 1997, M15 South Ferry Branch service was rerouted via Allen Street and Madison Street between East Broadway and St. James Place, instead of running via East Broadway and St. James Place. The change eliminated awkward turns in Chatham Square and allowed bus service to avoid congested East Broadway. The change was expected to save two minutes in travel time.[84] Effective January 13, 1997, 108 weekday M15 Limited trips were added to the schedule.[85] The Park Row branch was eliminated on June 27, 2010, and replaced by the M9 due to budget crisis.[54] Select Bus Service on the M15 began on October 10, 2010, replacing limited-stop service.

M34 M34A	New York City Omnibus Corporation bus route (M19 - 16) replaced New York Railways' 34th Street Crosstown Line streetcar on April 1, 1936. M16 service to Waterside was moved from the FDR Drive to Second Avenue in the 1980s. The main route was renumbered the M34 in April 1986. The M16 was cut from Pier 83 to Port Authority Bus Terminal on September 10, 1995, as part of a series of service cuts enacted to cover a $113 million budget deficit, eliminating overlap with the M42. Residents of the neighborhood testified at the April 18, 1996 meeting of the New York City Transit Committee of the MTA Board in opposition to the cut, and in response, NYCT studied M42 service west of 42nd Street to see if it was adequate. The study found that M42 service was adequate. However, after meeting with members of the neighborhood, the western terminal of M16 service was moved to West 43rd Street, and the first southbound stop was moved to the corner of 42nd Street and Ninth Avenue.[94] Select Bus Service started on November 13, 2011, and the M16 was renumbered to the M34A.[95] Alternate trips on the M34 to/from Waterside Plaza were added on September 3, 2017.

The route was extended further west from Lenox Avenue to Broadway and West 106th Street in 1997.[100] On June 23, 1998, weekday service was increased to run every 20 minutes between 11 a.m. and 7 p.m.[85] The route was converted to Select Bus Service on May 25, 2014.[101]
M66	Comprehensive Omnibus Company began operating bus route (M7) on February 15, 1935.[102] Route M7 became M29 in July 1974 and M66 c. March 1989.[89] In November 1987, the MTA Board approved plans to reroute its eastern terminal loop and to renumber the route the M66. Eastbound service was rerouted from running east along East 68th Street, north along York Avenue, west along East 71st Street, and north along First Avenue, to running north directly along First Avenue after running east on East 68th Street. The route's terminal was moved from York Avenue and East 70th Street to York Avenue and East 69th Street. This change formalized a detour that was regularly made to avoid vehicles blocking East 68th Street between First Avenue and York Avenue. The change also eliminated two difficult turns.[103] Overnight service was discontinued on June 27, 2010, due to a budget crisis.[54]
M72	The M72 was created on September 10, 1989, to provide crosstown service on 72nd Street from East 72nd Street and York Avenue to 66th Street and Freedom Place via the 65th Street Transverse.[67] On December 20, 2009, due to New York State Department of Transportation construction on West 72nd Street, service was rerouted to a new terminal on West 66th Street between Riverside Boulevard and Freedom Place. Due to that construction, service had been rerouted via Riverside Boulevard, West 68th Street and Freedom Place. To bypass congestion on West 68th street, westbound service was rerouted via West 66th Street to the new terminal.[104]
M79	New York City Department of Plant and Structures began operating bus (M4 – soon became NYCO's 17) on November 30, 1921. Operated by Green Bus Lines from 1933 to 1936, then taken over by New York City Omnibus Corporation on June 22, 1936.[105] On September 27, 1987, the M17 was renumbered the M79, and some minor changes were made at the route's western terminal to eliminate having the route turn around on residential streets. The route's terminal was moved from West End Avenue and 81st Street to 79th Street and Riverside Drive. Westbound buses would continue west on 79th Street past Broadway to Riverside Drive to the terminal and then loop around the traffic circle to return in eastbound service. Previously, buses had a terminal loop of Broadway, 81st Street, West End Avenue, and 79th Street.[106] Select Bus Service began on the route on May 21, 2017.

Route	History
M86	New York City Omnibus Corporation bus (M5 - 18) replaced New York Railways' 86th Street Crosstown Line streetcar on June 8, 1936.

Original northern terminus was at Riverdale-Broadway/West 230th Street. Service was extended to 239th Street and Riverdale Avenue on February 14, 1965, to replace the former Bx10A service. The extension of the M100 ran via 231st Street, Irwin Avenue, Johnson Avenue, Kappock Street, the Henry Hudson Parkway service road, 239th Street, and Riverdale Avenue.[110] Service was further extended to Riverdale Avenue-West 262nd Street in July 1974. On February 19, 1984, weekday service terminated at Henry Hudson Parkway-West 246th Street, while all weeknight late evening and all weekend service continued to Riverdale Avenue-West 262nd Street. On March 5, 1989, the M100 saw further reductions in service, as the Bronx portion was split into the Bx20, but was not extended to Riverdale-West 262nd Street. These service cuts took place in order to address unreliable service.[111] Service initially terminated at West 207th Street-Tenth Avenue.[112] Service was extended from Inwood-207th Street to 220th Street-Broadway to serve the Allen Hospital, a satellite facility of NewYork-Presbyterian Hospital on September 7, 1997.[113] Also on this date, service was extended on the route's south end from Third Avenue to Second Avenue.[114] In September 2013, the route was extended to First Avenue and 125th Street to provide additional service on 125th Street.

M106	Manhattan and Bronx Surface Transit Operating Authority began operating bus on September 10, 1962, as the M107 on a six-month trial basis. Bus service ran every 15 minutes between 6:30 a.m. and 10:30 p.m. from Monday through Saturday, and 30 minutes during these hours on Sundays and holidays. Originally ran from 106th Street and the FDR Drive to 110th Street and Riverside Drive.[124] In Fiscal Year 1963, this route was extended at the request of residents along the route.[53] Its western terminus was cut back to 106th Street and Fifth Avenue on May 24, 1964.[121] Became a branch of the M19 (which is now the M96) on January 7, 1974. The main branch of the M19 became the M96 in May 1993, and the 106th Street branch of the M19 became the M106 in 1996 when it was rerouted to use Madison and Fifth Avenues instead of Lexington and Third Avenues.

Originally, after the first stop, buses turned right on Westchester Avenue, right on Brook Avenue, right on East 145th Street, left on Willis Avenue due to construction. After construction was cleared, buses turned left on Westchester Avenue, left on Third Avenue, left on East 146th Street, right on Willis Avenue.

2020s redesign

As part of the MTA's 2017 Fast Forward Plan to speed up mass transit service, a draft plan for a reorganization of Bronx bus routes was proposed in draft format in June 2019, with a final version published in October 2019. Many of the draft proposals were not included in the final version. These changes were set to take effect in mid-2020, but delayed due to the COVID-19 pandemic in New York City.^[126] These changes include modifications to the M100 route in Manhattan as well as the addition of a crosstown M125 bus route.^[127][128] The redesign took effect on June 26, 2022.^[116][117]

Former routes

Except for early Fifth Avenue Coach Company routes, which were approved by the New York Legislature, all routes were assigned a franchise by the city, numbered in order from M1 to at least M47 and M100 to M106. Most companies used these numbers, but the New York City Omnibus Corporation (NYCOC) gave its routes numbers from 1 to 22, and the Fifth Avenue Coach Company used numbers from 1 to 20. The public designations were not changed to avoid conflicts until July 1, 1974.^[59]

Originally ran from Bleecker Street to 89th Street. Extended north to 135th Street on August 5, 1900. Assigned route number 1 around 1916 or 1917. After c. 1950s, one trip per day remained to maintain the franchise. This route was discontinued on March 1, 1962, after MaBSTOA took over Fifth Avenue Coach operations; today's M1 is of no relation to this route.[121][135]
M2 (NYCOC 12)			79th Street Crosstown	This route was renumbered M12 in 1972.[59]
M2 (NYCO)			Fourth and Madison Avenues	Along with the current M1 (see History of the current Manhattan bus routes), replaced streetcars on the Fourth and Madison Avenues Line on February 1, 1935. Extended west via 116th Street and north via Lenox Avenue to 146th Street on July 17, 1960, and then one block north to 147th Street on April 30, 1967. Southbound buses moved to Fifth Avenue on January 14, 1966; was a separate and distinct route from today's M2. This route was discontinued on March 2, 1969, and replaced north of Lenox Avenue and 116th Street by the M101A (today's M102).[121][136]
M3			49th and 50th Streets Crosstown	This route was renumbered M27 on July 1, 1974.[59]
M4 (NYCOC 17)			79th Street Crosstown	This route was renumbered M17 in 1972.[59]

M6	South Ferry Whitehall Street and South Street at South Ferry/Whitehall Street (​​​ trains)	Midtown Manhattan Sixth Avenue and Central Park South	Broadway and Sixth Avenue	New York City Omnibus Corporation buses route (M23 - 5) replaced New York Railways' Sixth Avenue Line streetcar on March 3, 1936. New York City Omnibus Corporation buses route (M22 - 6) replaced New York Railways' Broadway Line streetcar on March 6, 1936. The routes were combined as a one-way pair on November 10, 1963, and kept the number 6. On March 22, 1976, a branch of the M6 started running, starting at Eighth Avenue and 41st Street, and running along 41st Street and Sixth Avenue.[122] The route through Midtown was shifted from Broadway to Seventh Avenue in 2009 due to the street's pedestrianization. The route was merged into M5 on June 27, 2010, due to a budget crisis. The Seventh Avenue section was discontinued.[54]
M7			65th Street Crosstown	The route was renumbered M29 on July 1, 1974.[59]
M8 (first use)	Varick Street and Grand Street	FDR Drive and Grand Street	Grand Street and Broome Street,	Avenue B and East Broadway Transit Company bus (M8) replaced Dry Dock, East Broadway and Battery Railroad's Grand Street Line streetcar on July 30, 1932. Operations taken over by Manhattan and Bronx Surface Transit Operating Authority in 1980. In October 1987, the MTA Board approved plans to discontinue the route due to low ridership. The route's averaged fewer than 550 daily riders, or an average of 6.2 passengers per trip. The MTA expected ridership on the route to decrease further due to competition from dollar vans on the FDR Drive end of the route and because service on the route was very unreliable due to congestion at the route's western end from traffic going to the Holland Tunnel. This route suffered heavily from bunching, and because service was scheduled very infrequently, this was very irritating for riders. The route's cost recovery ratio was only 37%. 65% of passengers used the route westbound, while only 35% used it heading eastbound. On weekdays, service ran every 15 minutes during the a.m. rush hour, every 22 minutes during middays and the p.m. rush hour and every 44 minutes during evenings. On weekends, service ran every 25 minutes middays and every 50 minutes during other times. Service on the M14A was recently rerouted to run bidirectionally along Grand Street between Essex Street and the FDR Drive. To reduce the effect of the change, a free transfer was instituted between the M14 and the M15 at Essex Street and Allen Street.[137] This route was scheduled to be discontinued in January 1988, but the change took effect on June 26, 1988.
