• Began on July 3, 1921.
• In April 1928, the original terminus was at Moshulu Parkway.
• Original north-western terminus was at Broadway-
  231st Street (
  train). Service was extended to Riverdale-West 246th Street in February 1984, and was later cut back to its current terminus in 1990 after the Bx7 started running all times except nights.
• Some Bx1 trips also ran via Paul Avenue and Bedford Park Boulevard in both directions until March 1993.
• Effective October 30, 1997, southbound buses no longer stopped at Paul Avenue, and used the main road of Mosholu Parkway instead of the service road between Paul Avenue and Sedgewick Avenue.[46]
• Original south-western terminus was at
  138th Street–Grand Concourse ( train). Southbound service was extended to its current terminus on September 8, 2002.^[47]
• In March 2002, the MTA announced a plan to revise service on the Bx1, Bx2, and Bx41 routes in Mott Haven by extending the Bx1 and Bx2 to a new terminal at Lincoln Avenue and East 138th Street and truncating the Bx41 to East 149th Street and Third Avenue. The Bx41 would have a terminal loop consisting of Third Avenue, East 146th Street, Willis Avenue, East 147th Street, and Third Avenue. At the time, the Bx1 had terminated at the
  Third Avenue–149th Street subway station. The changes were intended to improve service reliability on the Bx1 and Bx2 by consolidating route supervision at their new terminal. There was no dispatcher at Grand Concourse and East 138th Street, and without full supervision, trips were often out of order when they merged at Grand Concourse and East 165th Street. The truncation of the Bx41 made the changes cost-neutral and ensured there would not be too many buses in the vicinity of East 138th Street and Lincoln Avenue. About 1,000 Bx41 daily riders would need to transfer with the changes.^[48] The changes took effect on September 8, 2002.^[49]

About 1,000 Bx41 daily riders would need to transfer with the changes.^[48] The changes took effect on September 8, 2002.^[49]
• On August 16, 2008, Bx2, Bx15, Bx41, and Bx55 service were rerouted in The Hub due to the reconstruction of streets by the New York City Department of Transportation to improve pedestrian safety. Bx2 service was rerouted off of East 165th Street and Melrose Avenue. Northbound service started running east via East 146th Street, north on Willis Avenue, north on Bergen Avenue, west on East 149th Street, and north on Grand Concourse, while southbound service continued along Grand Concourse to East 149th Street, turned east on that street, south on Courtlandt Avenue, and south on Third Avenue. Southbound Bx15 service would stay on Third Avenue until East 146th Street, and run along that street and Willis Avenue before returning to its previous route. Northbound Bx41 service would run north on Third Avenue, west on East 152nd Street, and north on Melrose Avenue before resuming its previous route, while southbound service would run south on Melrose Avenue, east on East 154th Street, south on Elton Avenue, and then south on Third Avenue before resuming its previous route.

• The MTA, in September 2001, announced a plan to reroute southbound Bx8 bus service off of Otis Avenue and Logan Avenue, which are narrow two-way streets, and onto the Bruckner Boulevard South Service Road and Hollywood Avenue in Schuylerville. The change would take effect in Fall 2001.^[69]
• In November 2002, the MTA announced a reroute of the Bx8 to run along Pennyfield Avenue and Harding Avenue instead of along the Throgs Neck Neck Expressway Service Road.

To maintain the transfer to the subway, bus-subway transfers were accepted on the Bx15 overnight. The change was made to eliminate duplicative service, which was lightly patronized. In addition, an unnecessary turn at 147th Street was eliminated. This awkward turn was initially done because a support pillar of the Third Avenue Elevated had prevented northbound buses from turning directly from Willis Avenue to Third Avenue.

To accommodate this extension, the original short turn service to Jerome Avenue-East 175th Street was discontinued and service to and from the hospital ran between 6AM and 11:30PM daily. Further recommendation also included the bus to bypass the West 195th Street area during non-school hours, running at Kingsbridge Road instead.^{[113][114][115][116]}

• In December 1999, the MTA announced a proposed change to service between Third Avenue and East 138th Street and East 134th Street and Alexander Avenue to enable the dispatcher at East 138th Street to better supervise service on the route, and to avoid traffic near Bruckner Boulevard. Bx41 would now share a terminal with the Bx21 and Bx32 at Lincoln Avenue and East 138th Street. After stopping at East 138th Street on Third Avenue, southbound service had previously run south on Lincoln Avenue and east along East 134th Street to its terminal. Northbound service continued east on East 134th Street, north on Alexander Avenue, west on East 135th Street, and north along Lincoln and Third Avenues. Only 100 daily riders alighted and only 200 daily riders boarded in the discontinued segment south of East 136th Street. The change was expected to save $50,000 a year. The change would take effect in early 2000.^[126]
• In July 2000, the MTA announced a roposed revision in the route's terminal loop at East 241st Street and Baychester Avenue. Instead of making a U-turn to head back west on East 241st Street and head south on White Plains Road, northbound buses would turn east White Plains Road at East 238th Street (Nereid Avenue), and then north onto Baychester Avenue before merging onto East 241st Street. The terminal would be moved from the south side of East 241st Street at Baychester Avenue to the north side of East 241st Street at Cranford Avenue. Two northbound bus stops on White Plains Road at East 239th Street and East 240th Street would be discontinued. The change would take effect in fall 2000.^[127]
• In March 2002, a plan to revise service on the Bx1, Bx2, and Bx41 routes in Mott Haven by extending the Bx1 and Bx2 to a new terminal at Lincoln Avenue and East 138th Street and truncating the Bx41 to East 149th Street and Third Avenue was announced. The Bx41 would have a terminal loop consisting of Third Avenue, East 146th Street, Willis Avenue, East 147th Street, and Third Avenue. At the time, the Bx1 had terminated at the
  Third Avenue–149th Street subway station. The changes were intended to improve service reliability on the Bx1 and Bx2 by consolidating route supervision at their new terminal. There was no dispatcher at Grand Concourse and East 138th Street, and without full supervision, trips were often out of order when they merged at Grand Concourse and East 165th Street. The truncation of the Bx41 made the changes cost-neutral and ensured there would not be too many buses in the vicinity of East 138th Street and Lincoln Avenue. About 1,000 Bx41 daily riders would need to transfer with the changes.^[48] The changes took effect on September 8, 2002.^[49]
• In 2009, as part of Phase II of the MTA and New York City Department of Transportation (DOT)'s Select Bus Service (SBS), both the Third Avenue and Webster Avenue bus corridors were studied for the implementation of a north-to-south bus rapid transit service through the South Bronx.^[128][129]
• The Bx41 along Webster Avenue was chosen for Select Bus Service since it would serve more riders and was wider, making it easier to accommodate bus lanes.^[130] In April 2013, the MTA Board approved the planned replacement of limited-stop service with Select Bus Service. The Bx41 SBS would make all the same stops as limited-stop service except or northbound stops at 189th Street and Westchester Avenue. Bx41 SBS service would use a new off-street stop at the Gun Hill Intermodal Terminal to improve the connection to the subway.^[131] The span of service would increase from being peak-hour-only to operating between 6 a.m. and 9:30 p.m.. Service on the Bx41 would increased 30 percent on weekdays, 22 percent on Saturdays, and 51 percent on Sundays. Offset bus lanes were installed between East 165th Street and East Gun Hill Road. Due to street modifications related to the bus lane at Tremont Avenue, westbound Bx36 and eastbound Bx40 and Bx42 buses were rerouted off one block of Webster Avenue and onto Valentine Avenue between East 178th Street and Tremont Avenue. As part of the changes, the Bx55 Limited along Third Avenue would be discontinued, and service between The Hub and Fordham Plaza would be replaced by the Bx15 Limited. The Bx15 Limited would run along the route of the Bx15 local between Fordham Plaza and 12th Avenue and West 125th Street in Manhattan at all times except late nights and weekends, and the Bx15 local would be truncated to The Hub when the Bx15 limited operated. It would make all the same stops as the Bx55 Limited south of Fordham Road except for East 174th Street, and the southbound East 161st Street stop. Service between Gun Hill Road and White Plains Road and Fordham Road would be discontinued; alternate Bx55 Limited trips had previously run along this section, making the same stops as the Bx41 Limited. The Bx41 change took effect on June 30, 2013, while the Bx15 changes took effect on July 1, 2013.^[132][133] The implementation of Bx41 SBS increased operating costs by $1.28 million a year, including $700,000 in cost savings from replacing the Bx55 with the Bx15 Limited^[129]
