Commonwealth Avenue


The City of Boston has committed to completely reimagine Commonwealth Avenue (Comm Ave), a victory for advocates who have pushed for years to make our city safer for all. The new design is a major step forward for the city and the 100,000 people who use Comm Ave every day.

Why Comm Ave? Why_Comm_Ave.jpg
  • Commonwealth Avenue is a major east-west artery running through the heart of the Boston University campus and serving people who walk, bike, use transit, and drive.
  • Bike use has increased 135% since 2007, pedestrian volumes have increased 80% since 2001, and car volumes have decreased as much as 31% since 1987 in the project area. (Source: Boston University Master Plan, sections 8.5.1-8.5.6).




Many people who bike at home and come from smaller towns are very afraid to ride their bike in Boston. One of the great benefits of having these bike lanes is that they will increase ridership and people will feel a lot more comfortable biking.”

Why Now? Why_Now_(Comm_Ave).jpg
  • In 2013,  a total of $17 million in local, state, and federal funding became available for the reconstruction of Comm Ave. The city proposed a design that would narrow sidewalks to offer more space for the Green Line tracks and wider travel lanes to be shared by people using cars and bikes.
  • LivableStreets had been focused on Comm Ave for nearly a decade when the city turned its attention to the street. By uniting partner advocacy organizations and the public, and by educating key decision makers, we helped win a design that includes protected bike lanes, raised crosswalks, improved bus stops, and transit signal priority for the Green Line and #57 bus.


“The process has been a great lesson on how fast the era of cycling has grown. There are many trade-offs when you do this kind of redesign, and you want to be careful you’re not asking too much of drivers, delivery trucks, and other traditional users of the same roadway. But with so many bicycles now, the highest priority is safety.
