Key bus routes of the Massachusetts Bay Transportation Authority (
MBTA
The Massachusetts Bay Transportation Authority (abbreviated MBTA and known colloquially as "the T") is the public agency responsible for operating most public transportation services in Greater Boston, Massachusetts. The MBTA transit network in ...
) system are 15 routes that have high ridership and higher frequency standards than other bus lines, according to the 2004 MBTA Service Policy. Together, they account for roughly 40% of the MBTA's total bus ridership. These key bus routes ensure basic geographic coverage with frequent service in the densest areas of Boston, and connect to other MBTA services to give access to other areas throughout the region.
In recognition of their function as part of the backbone MBTA service, the key bus routes have been added to newer basic route maps installed in subway stations and other public locations. These schematic route maps show the rail rapid transit routes, bus rapid transit routes, commuter rail services, and key bus routes. The key routes have been treated as a distinct category for the purpose of service improvement, such as trial runs of late-night service, and due to the high volume of passenger traffic they carry, both individual routes and the category as a whole have been the subjects of urban planning and transportation engineering studies.
History
In November 2006, the MBTA launched a concerted effort to improve service quality on key bus routes. The 2008 Service Plan recommended improvements for various lines, including upgrading the 31 bus to key route standards. A second round of upgrades, entitled the Key Routes Improvement Project and costing $10 million in all, was supported by the American Recovery and Reinvestment Act of 2009. The Silver Line services were originally considered part of this program, but were later split off into a separate enhancement project. The initial Key Routes Improvement Project was concluded in 2013, with some planned upgrades not being made. Due to these changes, the reliability of service (as measured by adherence to posted service frequencies) has been found to be greater on the Key Routes than on others, with 75% versus 61% respectively in June 2017.
A 2012 statistical analysis found that proximity to key bus routes was inversely correlated to taxicab trip generation, whereas taxicab trip generation actually increased with proximity to bus routes overall, suggesting that only the routes with highest frequency were able to compete with taxi service among customers with the option to choose.
In April 2014, extended late-night service on the key bus routes and rapid transit routes was announced, to be operated on a one-year trial basis with service continuation depending on late-night ridership and on corporate sponsorship. , late-night service was cut back from 2:30am to 2:00am, and extended hours were dropped from 5 of the 15 key bus routes. Late-night service was discontinued altogether in March 2016.
The category of key bus routes figured into Boston mayor Marty Walsh's "Go Boston 2030" initiative, which included the goal of having "every Boston household" within a 10-minute walk from a T station or a bus stop on a key route. In addition, a new key route was proposed to connect the Longwood Medical and Academic Area with

.
In May 2022, the MBTA released a draft plan for a bus network redesign, which included potential changes to most of the key routes. A number of other routes would be upgraded to key bus route frequency, forming a high-frequency bus network complementing the rapid transit network.
Key routes criteria
The MBTA's Service Delivery Policy uses five criteria when determining if a route is part of the Key Bus Routes program.
* High ridership demand
* Connectivity within the system
* Geographic coverage
* Accommodation of major new development
* Operation as

Policy standards
A bus route that has been identified as a key route must adhere to two policy standards: Span of service and frequency of service, both of which mandate service levels well above a standard local route. The following tables outline these standards as compared to standard local routes.
Route list
There are 15 key routes within the MBTA system: 1, 15, 22, 23, 28, 32, 39, 57, 66, 71, 73, 77, 111, 116, and 117. Elected officials and members of the public have asked the MBTA for limited-stop or express service along all of these routes.

A 2017 study of fare-card and vehicle-location data suggested that the 23 and 28 routes were overcrowded, and that this could be ameliorated by extending the 29 route and increasing its service frequency. A city-funded program includes fare-free service on routes 23, 28, and 29 from March 1, 2022 to February 29, 2024. No changes to the route were proposed in the May 2022 draft network plan.
28
The 28 Mattapan Station–Ruggles Station route provides service through the Grove Hall and Mattapan neighborhoods on Blue Hill Avenue, a major radial arterial. Blue Hill Avenue has long been a busy trunk route; in 1945, route 29 Mattapan– Egleston peaked at 1.5 minute headways during the morning rush hour. Streetcars formerly had a dedicated right-of-way on Blue Hill Avenue; streetcars were moved into mixed traffic in stages between 1940 and 1950, and replaced with buses in 1955. With the May 1987 changes to the bus network, route 28 was established to supplement route 29 service; both ran from Mattapan to Ruggles via different routings. In December 1989, route 28 became the dominant service on Blue Hill Avenue, and route 29 was relegated to a rush-hour-only route running only to Jackson Square. Shelters were added at some stops in 2001. From December 2006 to June 2010, short turn service between Franklin Park and Dudley (Ruggles after March 2007) was operated in the morning peak as route 25.

(BRT) express overlay for the 28, was briefly revived in 2006 as part of Silver Line Phase III plans. In 2009, the state proposed to add a limited-stop BRT line called the 28X on the corridor, which was then the busiest bus corridor in New England. The plan called for dedicated bus lanes on Blue Hill Avenue and queue jumps on Warren Avenue. The project was expected to cost $114 million. Construction was to begin in April 2010, with initial service at the beginning of 2012.
However, the proposal quickly drew opposition: it had been announced at a press conference by state officials without local officials having even been informed of the project, leading to accusations that the plan was rushed to qualify for TIGER grant funding without community input. Residents also objected because the dedicated bus lanes would require removing parking spots and the median strip, and the construction process would disrupt traffic on Blue Hill Avenue for over a year. The state withdrew the proposal in late 2009. In June 2010, the MBTA replaced 40-foot buses on the route with 60-foot buses; although the swap added capacity on the busy route, residents objected to the removal of some bus stops in hilly Grove Hall to accommodate the longer vehicles. In 2012, the Roxbury–Dorchester–Mattapan Transit Needs Study recommended the 28X bus to be implemented with no new infrastructure as an express bus adding additional trips to the corridor.
In August 2020, the MBTA and the city applied for $15 million in federal funds for a planned $30 million construction of Blue Hill Avenue. The project would include center-running bus lanes and be completed by the end of 2021. The federal government rejected the funding request in September 2020. A second $25 million application was submitted in July 2021. A pilot program of free fares and all-door boarding on route 28 is running from August 29, 2021, to February 28, 2022. The $500,000 pilot, funded by the city using American Rescue Plan monies, intends to reduce travel times on the frequently-late route. A city-funded program includes fare-free service on routes 23, 28, and 29 from March 1, 2022 to February 29, 2024. In November 2021, the city was awarded a $15 million federal grant (out of $39.5 million project cost) for the Blue Hill Avenue reconstruction.
The May 2022 draft network plan proposed that route 28 be extended from Roxbury Crossing to via the Longwood Medical Area; the Roxbury Crossing–Ruggles segment would be discontinued.
32
The 32 Wolcott or Cleary Square–Forest Hills Station route runs along Hyde Park Avenue from Forest Hills to Readville, serving Jamaica Plain, Roslindale, and Hyde Park. It parallels the commuter rail tracks from Forest Hills to Readville for its entire route.
Up until 1953, Route 32 was a full-service trolley route from Forest Hills to Cleary Square, until it converted to trackless trolleys. In 1958, all trackless trolley services south of Forest Hills were discontinued and replaced by diesel buses. (The trolleys ended in the middle of Hyde Park Ave; however, a loop for the trackless trolleys to turn around was placed on Hyde Park Avenue and Pine St.)
In 1981, the former Route 31 bus route between Mattapan Square and Wolcott Square was consolidated with Route 32 at Cleary Square to become Route 32 Forest Hills–Wolcott Square. Route 50, which served Cleary Square and Forest Hills via Roslindale, was rerouted onto River St, Gordon Avenue, Summer St (inbound) and Austin St (outbound) to serve the Summer St Elderly Housing Area (aka Malone Elderly Housing). No changes to the route were proposed in the May 2022 draft network plan.
39
The 39 Forest Hills Station–Back Bay Station route is the replacement (described as "temporary" from 1985 until 2011) for Green Line E branch service from Heath Street to Arborway which has run since December 1985. Aside from paralleling the Green Line from Heath Street to Copley, there are connections to the Orange Line and commuter rail at both ends (and Amtrak at the

At the Harvard end, to turn around, the bus exits the tunnel and makes a hard left onto Massachusetts Avenue and a right on Garden Street, and then turns right on Waterhouse Street and right on Massachusetts Avenue to return to the tunnel. The Watertown end has a loop on private right-of-way for turning around and picking up/dropping off passengers.

Routes 71 and 73, along with the adjacent routes and , ran with trolleybuses (locally referred to as "trackless trolleys") for decades after all such other routes in the MBTA system had been eliminated, representing some of the last vestiges of Boston's once-extensive trackless trolley network. They were finally converted to diesel bus operation on March 13, 2022.

Until the Red Line Northwest Extension opened in the 1980s, routes 77/77A provided the bulk of transit service northwest of Harvard, with combined streetcar headways under one minute during rush hours in 1945. Route 77 was converted to diesel bus in 1955; route 77A (Harvard– North Cambridge carhouse short-turn service) was converted to trolleybus in 1958 to free up streetcars for the upcoming Highland branch conversion, and so that boarding islands on Massachusetts Avenue could be removed to benefit automobiles. Route 77A formerly provided all local service south of the carhouse, with route 77 making limited stops on that segment; however, it was largely replaced by route 77 service in stages from 1998 to 2005, and eliminated entirely in 2022. In 2017, Arlington applied for a private grant to add signal priority, queue jumps, and possibly bus lanes on their section of the route. No changes to the route were proposed in the May 2022 draft network plan.
111
The 111 Woodlawn–Haymarket Station provides a route between downtown Boston and parts of Chelsea, via the Charlestown Bridge and the Tobin Bridge. (Some trips formerly continued east as far as Revere.) When the Boston Elevated Railway bought the route in 1936, it ran as streetcars between Chelsea Square and Woodlawn. On October 10, 1936, the line was replaced by an extension of the City Square–Chelsea Square bus route. The line was extended in April 1975 to Haymarket after the closure of the Charlestown Elevated; the partial extension beyond Woodlawn was done in January 2001. Service past Woodlawn was discontinued in September 2019, while Cary Square short turns were replaced by Woodlawn trips in December 2021.
The 111 is among the most frequent numbered MBTA bus routes, with service running every 5 minutes during rush hour. No changes to the route were proposed in the May 2022 draft network plan.
116/117
The 116 Wonderland Station–Maverick Station via Revere Street and 117 Wonderland station–Maverick station via Beach Street serve East Boston, and the cities of Chelsea and Revere. The 116 and 117 share most of their routes through East Boston and Revere, differing only on the northern end near
