Officials in Cambridge are working on a plan to permanently block off a street in Harvard Square to car traffic, allowing pedestrians to use it instead.
The pedestrianization of Lower Bow Street would start next spring, coinciding with the beginning of the 2026 outdoor dining season, according to a Sept. 11 letter from Transportation Commissioner Brooke McKenna to city councilors.
The street has already been closed for construction for years, without causing significant impacts, McKenna said in the letter. The construction projects have ranged from building renovations to road repaving, according to city spokesperson Jeremy Warnick.
“This has demonstrated that from a traffic perspective, this location is an excellent opportunity for pedestrianization,” she said.
McKenna said the permanent closure of Bow Street could benefit local businesses, with opportunities for outdoor dining.
The plan was discussed by the Cambridge City Council on Sept. 15 and set in motion.

Where exactly would the road be closed?
Lower Bow Street would be closed permanently between Dewolfe and Plympton streets, according to McKenna.
The road has already been closed temporarily, and the area was utilized during the COVID-19 pandemic for outdoor dining, she said.
Officials deciding what materials to block roadway with
McKenna said in her letter that city officials had not yet determined what materials to use to block the roadway, but would consult with stakeholders, including Harvard University and the Harvard Square Business Association.
However, the City of Cambridge has “serious reservations about the reliability, maintenance burdens, installation challenges, and costs of automatic bollards,” she said.
The city plans to pursue its options, and the council voted unanimously to place the discussion “on file.”
