SomerStreets is the City of Somerville’s take on the internationally-renowned Open Streets concept, closing busy city streets to vehicles, and opening them up for cycling, walking, dancing, running, and other modes of activity.

Through SomerStreets, the City and its community partners aim to promote and encourage easy access to physical activity and reconnect with neighborhoods and businesses and their unique cultural elements in a thriving urban environment.

SomerStreets builds on the Shape Up Somerville healthy living initiative. Similar open streets events take place all around the world, providing space normally taken up by automobile traffic for people to be more active.

SomerStreets is an annual series that takes places on Sundays during the summer and fall.
