Mount Auburn Street Project Progress Update

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

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.
