This is a brief overview of construction operations and traffic impacts for the Tobin Bridge/Chelsea Curves Rehabilitation Project. MassDOT will provide additional notices as needed for high-impact work, temporary ramp and street closures, and changes to traffic configurations beyond those described below.
•No Work on July 4
No work will take place on Thursday, July 4 for the Independence Day holiday.
*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.
*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.
Drivers should take care to pay attention to all signage and move carefully through the work zone. Police details, changes in lane markings, temporary controls such as barriers and traffic cones, signage, and other tools will be used throughout the project to control traffic and create safe work zones.
The contractors are coordinating with local event organizers and police to provide awareness and manage traffic impacts during events. For your awareness, during this look-ahead period, the following events are scheduled:
*Boston Pops July 4th Fireworks Spectacular (Charles River Esplanade): July 3 at 8:30 p.m., July 4 all day
*Red Sox (Fenway Park): June 30 at 10:10 a.m., July 12 at 7:10 p.m., July 13 at 7:15 p.m.
