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 Westbound.
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 (both directions). This work will be shut down for the winter during the week
of November 22.
A contractor performed preparatory work in the Prudential Tunnel Westbound in
advance of the upcoming Hynes Convention Center ceiling repair project.
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 survey work for an upcoming weekend project in the I-90
Tunnel (both directions).

MassDOT workers cleaned the pump wells in several pump stations in the vicinity of
Ramps D (Congress Street, Boston, to I-93) and F-D (Ted Williams Tunnel
Westbound, Exit 24 to I-93).
MassDOT workers performed preventative maintenance on a drainage device in the
Callahan Tunnel.
Clear Channel workers gained access to the Sumner Tunnel to perform preventative
maintenance on one of Clear Channel’s billboards at the tunnel exit. The workers
also installed a new advertisement on the billboard. The work required a lane and
ramp closure.
