Pearl Street Reconstruction Project

Pearl Street from Massachusetts Avenue to Granite Street

Work to resume Spring 2018.


Pearl St Base Paving to Begin on Monday, August 14

Due to an unforeseen conflict with the paving sub-contractor, the roadway base paving on Pearl St. (between Granite St. and Erie St.) will now begin on Monday, August 14th and last approximately 2 days, weather permitting. This is in preparation for final roadway paving of the whole length of Pearl St (Mass Ave to Granite St) which will occur in the spring/summer of 2018.

Detours will be in place during work hours. Please look for Detour signs, Road Closed signs, and signs indicating 2-way traffic is being allowed on normally 1-way streets to accommodate access to properties.

After work hours each day and all day on weekends, vehicles will be able to access, park, and travel on Pearl St. Please be mindful when parking that during certain stages of the work the roadway may be lower and car doors may come in contact with the curb.

Once base paving is complete, crews will begin curb and sidewalk demolition and reconstruction on Pearl Street between Granite St. and Erie St. through the fall with estimated completion in spring 2018. During this work, sidewalk detours for pedestrians will be in place. “No Parking” signs will also be present and changing frequently, so please check all posted signs.

What to Expect During Construction:
• General work hours 7am-4pm, Monday through Friday.
• Please check posted No Parking signs.
• Please follow Detour signs and look for Road Closed and 2-Way Traffic signs.
• The roadway will be lower, making the curbs higher for parked cars. Please use caution when opening car doors as to not damage them on the curbs.
• Access will be maintained for abutters whenever possible. During work hours, abutters will be allowed to travel the wrong way down one way streets in order to access their property. Caution should be used. After work hours, roadways will reopen for all in their normal travel directions.
• Please follow sidewalk detours for pedestrians.
• Access will be maintained for emergency vehicles.

Mass Ave Sidewalk Reconstruction
Curb/sidewalk work to begin week of May 29

The City’s contractor, Onyx Corp, will begin sidewalk maintenance work on Massachusetts Avenue after Memorial Day during the week of May 29th. This work is anticipated to last approximately 4 weeks, weather permitting.

Continuing on the previous sidewalk work that was completed in Central Square, sections of sidewalk on the south side of Mass Ave will be reconstructed in the YMCA block (Sellers to Pleasant streets) & Dunkin Donuts block (Carl Barron Plaza to Pearl St.) Please see map below showing approximate work area.

Map of Mass Ave Sidewalk Work

Work will include accessible sidewalks (concrete walkway and brick furniture edge) as well as bike parking. Public Works has coordinated with adjacent property owners concerning areaways present under the public sidewalks in these locations, and work has been completed to abandon the areaways so the sidewalks can be reconstructed.

During this work, sidewalk detours for pedestrians will be in place. “No Parking” signs will also be present and changing frequently, so please check all posted signs.

• Please follow pedestrian detour signs.
• Access to businesses and properties will be maintained, when possible.
• Access will be maintained for emergency vehicles and City services.

May 2017

Curb and sidewalk work continues on pearl St from Auburn St. to Watson St.

Crews will begin the construction of the Green St curb extension and work on Mass Ave sidewalks between Sellers and Pearl streets toward the end of May/beginning of June.

Notices with more information will be delivered to affected residents and businesses in the coming weeks.


Pearl Street Reconstruction Project - March 23, 2017
Curb/sidewalk work to resume the week of March 27, 2017

The City’s contractor, Onyx Corp, will resume sidewalk reconstruction on Pearl Street between William St. and Auburn St. beginning the week of March 27, 2017.

Once complete, crews will continue sidewalk work in the direction toward Mass Ave.

During this work, sidewalk detours for pedestrians will be in place. “No Parking” signs will also be present and changing frequently, so please check all posted signs.

As you will see, multiple sections of existing sidewalk panels will be left in place as crews complete their work. The reason these panels will remain in place is that there is additional work in these areas that needs to be performed by the gas company to replace services to properties. Once completed, these panels will be temporarily paved with asphalt to make the sidewalks safe and passable. These panels will be replaced with concrete to match the rest of the street before the project is finished.

Access in and out of properties will be maintained but could be restricted at times.

What to Expect During Construction:

  • General work hours will be 7am – 4pm, Monday-Friday.
  • Please check posted No Parking signs.
  • Please follow detour signs.
  • Access will be maintained for emergency vehicles and City services.

Pearl Street Reconstruction Project - March 2, 2017

Gas main replacement work to begin on Monday, March 13th

In association with the Pearl Street Reconstruction Project, Eversource Gas will mobilize to replace the gas main on Pearl Street between Mass Ave and Chestnut St on Monday, March 13th. The replacement of the gas main between Granite and Chestnut was completed in 2016.

Eversource has committed to having two crews assigned to help expedite the work replacing the gas main as well as 21 house services and 7 side street tie-ins. These tie-ins will extend approximately 30 feet into each side street and those sections will be repaved as part of the paving of Pearl Street. Eversource is anticipating the duration of this replacement to last for approximately eight weeks, weather permitting.

To minimize disruption to residents, the City coordinated with Eversource to have this work done now to replace the old gas main to minimize future gas leaks and not require the new street and sidewalks to be opened up for utility work once the Pearl Street project has been completed.

The City’s Contractor, Onyx Corp., will begin sidewalk reconstruction on Pearl Street at Mass Ave and working toward Erie St. beginning in early April. Sidewalk work will be completed between Mass Ave and Erie St. before continuing on between Erie St. and Granite St.

To ensure that the roadway conditions will be favorable for many years to come, crews will engage in full-depth reconstruction of the roadway once Eversource completes its gas main replacement work.

We kindly ask that motorists drive through the construction zone slowly during general working hours. Final roadway paving will be scheduled and announced via an additional notice in the coming weeks, but will occur sometime in spring of 2018.

What to Expect During Construction:
  • General work hours 7am-4pm, Monday through Friday.
  • Please check posted No Parking signs.
  • Please follow detour signs when in place.
  • The contractor will work with local businesses to minimize any disruption to local deliveries.
  • Access will be maintained for emergency vehicles.

For Information and Assistance During Construction:
If you have any questions about the construction or need assistance, including if you have any special needs or disabilities that requires a special accommodation, please contact Dan Riviello, Community Relations Manager, at (617) 349-4825 / driviello@cambridgema.gov or Lou Mothon, Project Engineer, at 617-349-4828 / lmothon@cambridgema.gov. In case of emergency, please call the Cambridge Public Works Department at 617-349-4800.

Thank you in advance for your patience and understanding during this construction.


Removal of Traffic Signal at Pearl/Putnam Intersection - January 11, 2017

The planned removal of the unwarranted traffic signal at the intersection of Pearl Street and Putnam Avenue will occur late in the week of January 16th or the following week, weather permitting.

The signal will be replaced by all-way stop signs. This removal was planned as part of the community process for the comprehensive redesign of Pearl Street, including raised intersections, curb extensions, and new crosswalks.

Removing unwarranted signals and installing appropriate traffic control devices improves compliance and safety for people walking, on bikes, and in cars.

Those with questions or concerns should contact the Traffic, Parking & Transportation Department at 617-349-4700.

Once complete, crews will continue working toward Mass Ave for the remainder of the construction season and will pick up where they left off next spring once construction resumes.

During the roadway reconstruction, crews discovered the existing gas main to be in poor condition. Eversource has recently started replacing the gas main and we expect this work to take approximately 12 weeks to complete. This includes work on Pearl St, Pearl St. Place, Tufts St, Chestnut St., Henry St., and Glenwood Ave.

During this work, sidewalk detours for pedestrians will be in place. “No Parking” signs will also be present and changing frequently, so please check all posted signs.

As you will see, multiple sections of existing sidewalk panels will be left in place as crews complete their work.

October 2015

The Pearl Street Reconstruction Project will be out to bid in Winter 2015. We expect to have a contractor selected in Spring 2016 to begin construction.


April 2015

On March 30, 2015, the City Manager provided an update to Cambridge City Councillors regarding the design of Pearl St.

"This is an update to the status of the Pearl Street reconstruction project, with background information in the attached previous communication.

We propose to reconstruct Pearl Street without making changes to the parking regulation at this time. The underlying streetscape proposal remains unchanged, regardless of whether parking regulations on the street are changed.

The reconstruction of Pearl Street will commence in the summer/fall of 2015 and be complete by fall of 2016. A thorough evaluation of project outcomes, including pedestrian/bicycle use, vehicle speeds, yielding to pedestrians, parking patterns etc., will be conducted after the project has been completed. Auto ownership rates, pedestrian comfort, bicyclist safety, and transit vehicle mobility will also continue to be monitored.

We also propose continuing discussions with staff and the community about future trials or pilots, with the additional assessment information from the evaluation in hand. Changes to the street that involve pavement marking or signing can be made after the baseline construction is complete. The potential for any signing or marking related to bicycling will be considered as part of the complete project evaluation, and can be installed at that time."

Please visit the Updates tab for the most up-to-date information and schedule for this project.


Work began in the Summer of 2016 and the City anticipates that work will be completed in June of 2018 (24 months).
