North Washington Street Bridgeconstruction look-ahead Jan. 24 through Feb. 6

This is a brief overview of construction operations and impacts for the North Washington Street Bridge Replacement Project.

Vibratory Hammer Noise Impacts

•A vibratory hammer is being used to install the five cofferdams which will be needed to build the piers of the new bridge. Installation of each cofferdam takes about two weeks. 

•The project has positioned a combination of hanging sound blankets and temporary barrier to minimize noise impacts from the vibratory hammer. These measures will be adjusted as needed and appropriate.

•Use of the vibratory hammer began on 10/6/20. Work hours are during the day (7 a.m. – 3 p.m.)

Description of Scheduled Work

•Installation of north and south abutment haunch, installation and maintenance of silt curtain, installation of drilled shafts, and sheeting and bracing of cofferdams.

Work Hours

•Most work will be done during the daytime (6:00 a.m. – 6:00 p.m.)

Work That Has Been Completed

•Prior to 1/24/21, crews continued preparatory work to build the new bridge. Cofferdam installation is 88% complete.

Travel Tips

The westerly sidewalk, Lovejoy Wharf stairs near Converse are open to the public with the opening of the temporary bridge, the adjacent section of the Harborwalk passing under the bridge remains closed.

The Tudor Wharf Walkway (under the bridge next to the water in Paul Revere Park) will be intermittently closed for safety during construction operations, with access provided via the Water Street underpass.
