The City’s Contractor, Indus, will conduct roadway preservation work the week of September 8. A truck will be spraying the roadway with a plant-based solution called Fog Seal. The solution goes down as a white, almost opaque spray, but once dry, it leaves a transparent “seal” over the pavement.

On Thursday, October 1, the City of Cambridge's contractor, Newport Construction, will remove the existing concrete pavers and replace them with asphalt at the two Super Crosswalks in Harvard Square.

As part of the River Street project, the City’s contractor P. Gioioso & Sons (PGS) will begin the next phase of full-depth roadway reconstruction and paving on or about June 1, 2026. This work is expected to take approximately three weeks to complete

As part of the Five-Year Street and Sidewalk Reconstruction Plan, Huron Ave, from Fresh Pond Place to Fresh Pond Parkway, is scheduled for reconstruction. This project will include paving, sidewalk improvements and utility installations. Cushing Plaza, located at Cushing Street and Huron Avenue, is scheduled for reconstruction to allow stormwater to infiltrate and provide enhanced biochar and compost soil for the new trees and garden plantings.

As the River Street Reconstruction approaches substantial completion this fall, several traffic pattern changes will be taking effect. Over the next few months, workers will install new signage, paving and street markings, including a new dedicated bus-only lane. This work will happen in sections rather than all at once. At the end of construction, River Street will have sidewalks, a parking and loading lane, one general-purpose travel lane, a dedicated bus-only lane, and a sidewalk-level bike lane.
