About the Project
The Mount Auburn Street project was initiated after a conceptual design was endorsed by the Town Council in November 2018. The Project Team submitted the 25% Design to the MassDOT in January 2020, and MassDOT held a 25% Design Public Hearing on November 4, 2021. Since then, the project team has submitted 100% Design plans for the corridor.
The Mount Auburn Street Project will transform the corridor into a Complete Street, providing safe and accessible options for all modes. This project will also provide increased efficiency on the MBTA Bus Route 71, improve traffic operations and pedestrian and bicycle accommodations, improve accessibility in compliance with the Americans with Disabilities Act (ADA), and improved aesthetics.
