Streets and Transportation Projects

Three City departments collaborate on the design, community engagement, installation, and construction for street and transportation improvements: the Community Development Department, Public Works Department, and Traffic, Parking, and Transportation Department.

Cambridge's Five Year Plan for Streets and Sidewalks outlines which streets the City is planning to reconstruct each year. Visit the City Construction Projects page for the latest list of reconstruction projects.

Aberdeen Avenue Safety Improvement Project: This project will lead to slower speeds on Aberdeen Ave to improve safety for all users. It will include crossing improvements, signal improvements and the installation of separated bike lanes.

Appleton Street Traffic Study: This project includes a complete review of the impact of a full-time left-turn restriction from Brattle Street (eastbound) onto Appleton Street (northbound).

Broadway Safety Improvement Project: This includes the installation of separated bike lanes on Broadway as part of the city's Cycling Safety Ordinance.

Danehy Park Connector: The Danehy Park Connector / New Street Path is a proposed multi-use path between Concord Avenue and Danehy Park. 

Grand Junction Multi-Use Path: The Grand Junction Multi-use Path is a proposed off-street multi-use path running alongside the existing railroad tracks in the Grand Junction corridor from Boston University Bridge to Somerville. The city's objective is to design, in as much of the corridor as possible, a 14-foot wide path with two-foot wide buffers on both sides. 

Harvard Square Kiosk and Plaza: A community process established a vision for the Harvard Square Kiosk and Plaza to be flexible, dynamic, and welcoming community assets that enhance the everyday life of Harvard Square, act as platforms for community gatherings, including civic, artistic, and social activities, and attract and serve a broad range of people.  

Linear Park Redesign: Linear Park, located in North Cambridge between Alewife Station and the Cambridge-Somerville city line, is a popular open space corridor for commuting and recreation. Given its age and condition, the City of Cambridge is undertaking the redesign and reconstruction of Linear Park between the Russell Field Fieldhouse and the Cambridge-Somerville city line, just north of Mass Ave. 

Main Street Safety Improvement Project: This quick-build project will install separated bike lanes along Main Street between Massachusetts Avenue/Lafayette Square and Portland Street. 

MassAve4 Cycling Safety Ordinance Projects: In the Cycling Safety Ordinance, sections of Massachusetts Avenue that have complicating factors were identified as the “MassAve4.” 

River Street Reconstruction Project: This project will redesign River Street (from Memorial Drive to Massachusetts Avenue) to meet everyone’s needs; address utility and infrastructure needs; and develop and install a new design for Carl Barron Plaza. The project includes the bus terminal at River and Magazine Street and the Carl Barron Plaza (the public plaza in front of the Amazon, Cambridge Savings Bank, and Holmes building).  

Safety Improvement Project on Cambridge Street: This project includes the installation of separated bike lanes on Cambridge Street between Inman Square and Second Street as part of the City's Cycling Safety Ordinance, along with improvements for people walking and using transit.

Vassar Street Safety Improvement Project: This quick-build project will bring separated bike lanes and related street safety improvements on Vassar Street from Memorial Drive to Amherst Alley.
