64 (MBTA bus)

64 (MBTA bus) is a local bus route operated by the Massachusetts Bay Transportation Authority (MBTA) in the Boston metropolitan area. It connects the Oak Square neighborhood of Brighton with the Kendall Square area of Cambridge, primarily via Commonwealth Avenue and Harvard Square. The route provides a critical east-west link for residents, students, and employees traveling between these major residential, academic, and commercial hubs.

Route description

The 64 bus originates at the Oak Square terminal in Brighton, adjacent to the Brighton High School campus. It proceeds eastward along Commonwealth Avenue, passing the main campuses of Boston College and Boston University, as well as the Boston University Bridge. After crossing the Charles River into Cambridge, the route serves Harvard Square, a major transit hub with connections to the Red Line and numerous other bus routes. It then continues east through Massachusetts Institute of Technology (MIT) territory, terminating at the University Park development near Kendall Square and the Kendall/MIT Red Line station.

History

The route's origins trace back to private streetcar operations in the early 20th century, later consolidated under the Boston Elevated Railway. It was converted to bus operation in the 1950s as part of the MBTA's system-wide modernization efforts following its formation. Significant routing changes occurred in the late 20th century to better serve the growing academic and biotechnology corridors around Kendall Square and University Park. The alignment through Harvard Square has remained a consistent feature, cementing its role as a connector between major Boston universities and the innovation district of Cambridge.

Service characteristics

The 64 operates weekday and Saturday service, with no Sunday or holiday trips. Weekday headways range from 20 to 30 minutes during peak periods, while Saturday service operates on a consistent 30-minute schedule. Service spans from approximately 5:30 AM to 1:30 AM, providing coverage for commuters, university students, and evening activity. The route is known for its high passenger loads during academic terms, particularly between Boston University and Harvard Square. It interfaces with key MBTA subway stations including Harvard and Kendall/MIT on the Red Line.

Rolling stock

The route is primarily operated with 40-foot diesel-electric hybrid buses, specifically the New Flyer XDE40 model, assigned from the Fellsway Garage in Somerville. These buses are part of the MBTA's standard fleet for local routes and feature accessibility amenities like low-floor design and ADA-compliant ramps. On rare occasions, standard diesel buses such as the New Flyer Xcelsior may appear on the route due to operational requirements or fleet availability issues.

Ridership and performance

Pre-pandemic, the 64 was among the MBTA's top twenty bus routes by ridership, consistently carrying over 5,000 passengers on a typical weekday. Ridership is heavily driven by the student populations of Boston College, Boston University, Harvard University, and MIT, as well as employees of the many technology and life sciences firms in Kendall Square. Performance metrics have historically been impacted by traffic congestion on Commonwealth Avenue and in Harvard Square, leading to irregular headways. The MBTA has studied potential improvements, including transit signal priority and dedicated bus lanes, to enhance reliability on this corridor.
