As the construction season winds down, we’d like to take a moment to highlight the work completed along Mount Auburn Street. While the more extensive road work is planned to come back in the spring, MassDOT and Newport Construction has made progress this season in working towards a safer, more accessible, and welcoming street.
This year’s efforts focused on two major segments: the Cambridge line to Arlington Street and Arlington Street to Boylston Street. Within these areas, crews completed essential infrastructure work, including:
Drainage installation
Electrical conduit wiring
Traffic signal foundations
Utility pole relocation
Removal of catenary pole bases along the entire corridor
Manhole relocations
Sidewalk excavation and concrete placement (Cambridge line to Arlington Street)
Granite curb installation (Cambridge line to Arlington Street)
Roadway milling
First and second layers of paving
Hydrant installation
Raising/resetting buried utility structures
Tree trench installation
Loaming of tree pits and grass strips
Much of this construction was concentrated in Coolidge Square. Below is a preview of what this vibrant district is expected to look like once the project reaches full completion.
Mount Auburn Street Project Update

Raising Buried Structures
Crews will be raising buried utility structures, such as manholes and valve boxes, within the newly paved area along Mount Auburn Street between Lloyd Road and Boylston Street.
Traffic Impacts
During this work, you can expect temporary lane shifts and possibly lane closures, but one travel lane in each direction will be maintained on Mount Auburn Street.
Business entrances will be maintained as well. Work in these areas will begin at 7:00 am each day and end before 5:00 pm.
