Mount Auburn Street Project Update Week of February 9 – 13, 2026
Scheduled Work: Drainage Installation & Test Pits
Crews will continue drainage installation and excavate test pits on Mount Auburn Street between Richards Road and Oakley Road and Winsor Avenue and School Street

Traffic and Sidewalk 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. Work will take place on the sidewalks, but they will remain open and accessible. 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.
Parking Impacts:
Street parking in the construction area on Mount Auburn Street will be restricted. Construction crews will post parking closure signs in those areas starting at 7:00 am and will be removing them from the area by 5:00 pm each day.
(Note: All dates are approximate and will be dependent on weather conditions and any testing yet to be performed.)
Resources from the City’s Economic Development Team
During construction in the Coolidge Square area, Watertown’s Economic Development team developed the below graphic to help residents get around Coolidge Square, whether by car, bike, bus, or walking. Keep up to date with any road closures, bus stop impacts, or parking limitations in the work detailed above! A larger version of this map can be found at Mount Auburn Street’s project website.
