Contractors are repairing water infiltration at multiple points within the O’Neill
Tunnel (both directions) and on related ramps. In addition, a team is inspecting and
repairing the fireproofing material in the areas of the Southbound Tunnel where water
infiltration repairs are underway.
Water infiltration repair work is also underway in the I-90 Connector Tunnel (both
directions) and the Ted Williams Tunnel Eastbound.
A contractor, working on behalf of Boston Properties, owner of the Prudential Center,
is continuing ceiling repairs in the Prudential Tunnel (both directions). That work is
nearing completion.
A contractor is performing a routine inspection of the Southbound side of the O’Neill
Tunnel and related ramps. A different contractor is undertaking a similar inspection
in the Northbound tunnel set. A contractor is also inspecting the Ted Williams
Tunnel Eastbound. A contractor is also inspecting the Sumner Tunnel.
MassDOT workers are removing ceiling panels at the entrance of the Ted Williams
Tunnel Westbound. These panels are in place at the entrance and exit portals to the
tunnel. The panels are attached directly to the ceiling and they are being removed as
a precaution because there is no way to monitor the connection between the panel and
the tunnel ceiling. The contractor is also removing similar tiles on the Eastbound
side. The contractor has completed pull-testing the ceiling anchors in the Ted
Williams Tunnel.
A contractor continued repair work on the roadway surface in the Ted Williams
Tunnel Westbound. This work will be shut down for the winter during the week of
November 22.
A contractor performed preparatory work in the Prudential Tunnel (both directions) in
advance of the upcoming Hynes Convention Center ceiling repair project. Recent
work was focused on conduit relocation and barrier installation for the crossover
setup.
A contractor is continuing preparatory work for the upcoming full closure of the
Callahan Tunnel. The work required a lane closure in the tunnel. The full tunnel
closure will begin in December.

A contractor performed work related to installation of All-Electronic-Tolling
equipment on the Tobin Bridge. The preparatory work required closure of Ramp T-L
(Tobin Bridge to Rutherford Avenue).
MassDOT repaired a sensor on a jet fan in the vicinity of Ramps SA-ST/CN (Cross
Street to I-93 Northbound and Sumner Tunnel to I-93 Northbound).
MassDOT repaired crash attenuators at Exits 24 (Government Center) and 20 (South
Station) in the I-93 Southbound Tunnel.
MassDOT closed Interstate-90 Eastbound at Exit 22 (Copley Square/Prudential
Center) to support work occurring on Interstate 93. While the ramp was closed,
MassDOT performed a variety of work, including bridge inspections, pump station
cleaning, ceiling repairs and core sampling.
A contractor tested and demonstrated the new wiring and lighting system in the
Storrow Tunnel. The work required closure of Ramp L-CS (Leverett Circle to I-93
Southbound).
MassDOT workers cleaned a pump station near the entrance to the I-93 Northbound
Tunnel.
