City of Boston and MASCO Partner to Make Longwood Avenue Safer

If you travel down Longwood Avenue to work, school or appointments (and chances are, you do) be on the lookout for some significant changes coming this spring.

After considerable analysis on the multi-modal transportation needs of the LMA’s patient and employee communities and input from cyclists, motorists and pedestrians, MASCO, in partnership with the City of Boston’s Transportation Department and Department of Public Works has developed a plan to repave and restripe Longwood Ave for safe travel from the Riverway intersection to Huntington Avenue.

“MASCO continually monitors how over 112,000 people daily – patients, employees, researchers and students – are commuting to the LMA. Through studies and improvements we work to enhance the commuting experience whether you walk, cycle, drive, or use public transit; while doing this we also focus on innovative improving safety,” explains Sarah Hamilton, MASCO Vice President for Area Planning and Development.

The new lane markings, due to be installed by the city in late June, include the following:

  • One half mile of bike lanes will be installed from Longwood at The Riverway to Huntington Avenue.

  • Bike boxes at Longwood and Brookline (both directions) and The Riverway (one direction) headed west.  A bike box is a large box painted bright green at the forefront of an intersection where a cyclist can overtake a vehicle and assume the front spot while lining up at a red light in order to take a safe turn. 







  • The crosswalks parallel to Brookline Avenue at Longwood Avenue will be enlarged by 10 feet to create a clearer crossing path for pedestrians.
  • A left turn lane will be striped on Longwood at Oscar Tugo Circle “Left Turn Only” for reduction of speed and improved pedestrian crossings.
  • A “Shared Bus/Bike Only Lane” will be installed at the intersection of Longwood and Brookline Avenue and will stretch most of the length of the Galleria block in the eastbound lane. 




  • A left turn only lane will be added at Binney and Longwood heading west towards Dana Farber Cancer Institute.
  • An eastbound lane in the stretch between Blackfan Circle and Harvard School of Dental Medicine will be repurposed for bike lanes and improved pedestrian crosswalks. An additional lane will be preserved at Oscar Tugo Circle for left turns only onto Avenue Louis Pasteur.

Commuters can expect to see the lane markings completed by early summer.

“The primary goal of Go Boston 2030, the City of Boston’s comprehensive transportation plan, is providing safe, reliable and equitable access in Boston for all people, whether they choose to move around by public transit, bike, cars or on foot,” said Chris Osgood, City of Boston Chief of Streets.  “In addition to being a ‘main street’ for the Longwood Medical and Academic Area, Longwood Avenue is a critical transportation corridor for the City of Boston and we are looking forward to the implementation of these improvements.”

Boston Transportation Department Commissioner Gina N. Fiandaca added, “The Longwood Avenue project is one example of the type of infrastructure project that Boston Mayor Martin J. Walsh provides for in his recommended FY19 budget. Several similar projects that are designed to advance accessibility and safety goals related to Go Boston 2030 and Vision Zero, are currently in the construction or design phase.”

The plan for improvements is the result of productive dialogue with members of the cyclist community, including Longwood Cyclists, Boston Cyclists Union and Livable Streets Alliance,  BTD , MASCO, and its member hospital and college transportation specialists.
