Tobin Bridge/Chelsea Curves rehabilitation update

The following is an update from MassDOT concerning the Tobin Bridge/Chelsea Curves Rehabilitation Project, with a look ahead through July 13. MassDOT will provide additional notices as needed for high-impact work, temporary ramp and street closures, and changes to traffic configurations beyond those described.

No Work on July 4

  • No work will take place on Thursday, July 4 for the Independence Day holiday.

Traffic Impacts

  • Route 1 Northbound: Approaching the Tobin Bridge from Boston, the workzone begins in the righthand lane. 2 of 3 travel lanes will be open during daytime hours (5 a.m. –10 p.m.) and at least 1 travel lane will be open during overnight hours (10 p.m.–5 a.m.).
  • Route 1 Southbound: Approaching the Chelsea Curves from the North Shore, the workzone begins in the right-hand lane at the Carter Street off-ramp. Just beyond the Carter Street on-ramp, the travel lanes shift to the right. 2 of 3 travel lanes will be open during daytime hours (5 a.m. –10 p.m.) and at least 1 travel lane will be open during overnight hours (10 p.m.–5 a.m.).
  • Ramps: All on- and off-ramps will remain open at this time.
  • Local Streets: The Spruce Street temporary reconfiguration will remain in place for approximately 2 months.

Preview of Upcoming Traffic Impacts

  • Beginning on Monday, July 15, the Fourth Street off-ramp will close for 1-2 months for required steel repairs, structural rehabilitation, and safety improvements.

Work Hours

  • Most work will occur in during daytime working hours (6 a.m.–2 p.m.) on weekdays. Some work will take place during afternoon (2 p.m.–7 p.m) and overnight hours (9 p.m.–5 a.m.) and on Saturdays (6 a.m.–2 p.m).

Summary of Work Completed

  • In the two weeks prior to June 30, crews shifted traffic to create continuous work zones, formed bridge deck, cured concrete, repaired steel, bridge deck, and joints, installed a dust containment system, power washed and excavated around support column footings, and placed concrete columns.

Description of Scheduled Work

  • Route 1 Northbound: Form bridge deck, place and cure concrete, and repair steel, bridge deck, and joints. Clean water from a hydrant will be used to cure the concrete and may drip off the structure due the condition of the existing drainage system on the bridge. Crews will also remove asphalt and begin bridge deck demolition in the right-hand side workzone through the Chelsea Curves.
  • Route 1 Southbound: Weld and paint new deflector plates.
  • Underneath the Structures: Replace and paint steel, continued installation of dust containment system, power wash and paint columns and support beams, excavate, drill, and grout around the support columns, and place concrete columns.
