2017: Separated Bike Installation Between Brattle Square and Mason Street

Separated bike lanes that were installed on Brattle Street closer to Harvard Square in 2017. Click here for information on this project.

This project will build on this previous work and extend separated bike lanes the length of Brattle Street to the intersection of Mount Auburn Street.

2018 Meeting: Long-Term Brattle St at Sparks St/Craigie St Intersection Safety Improvements

In 2018, we held a community meeting presentation about long-term improvements at the Brattle Street/Sparks Street/Craigie Street intersection.

As part of that community process, the community selected a roundabout as the preferred alternative for this intersection. Funding for roundabout construction is not identified at the moment in the city's Five Year Plan for Sidewalk and Street reconstruction.

As part of this process, we can install interim improvements at this intersection. We will also refine design and cost estimates for the long-term proposal. We do not have a timeline for work on the roundabout at this time.
