Three City departments collaborate on the design, community engagement, installation, and construction for street and transportation improvements: 

Community Development Department,  Public Works Department, and Traffic, Parking, and Transportation Department. 

Belmont Street Reconstruction Project: Belmont Street, from the Belmont town line to Mt. Auburn Street, is scheduled for upcoming street and sidewalk reconstruction.

Brattle Street Safety Improvement Project: This quick-build project will install separated bike lanes on Brattle Street between Mason Street and Mount Auburn Street and make improvements to pedestrian crossings.

Chestnut Street Reconstruction Project: Chestnut Street from Sydney St. to Pleasant St. is scheduled for reconstruction in 2023 as part of the City's Five Year Plan for Sidewalk and Street Reconstruction.

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. 

Hampshire Street Safety Improvement Project: This quick-build project will install separated bike lanes along Hampshire Street between Inman Square and Broadway. 

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.”
