Weekly Look-Ahead: Sumner Tunnel Toll Plaza Reconstruction (December 2017)

3


WEEKEND WORK:

This upcoming weekend, MassDOT will be performing enabling work to shift the Route 1A Southbound traffic lanes into the Phase 3 alignment to allow for continued construction of the mainline roadway and local streets. This weekend’s work will consist of forming the median barrier between Route 1A SB and NB at the viaduct to tie the precast concrete barrier into the existing bridge barrier.

The left lane closure will be implemented starting at the exit portal of the Callahan Tunnel north to the bridge viaduct. The left lane closure will be in place on Saturday 12/2 from 6:00am – 3:30pm and Sunday 12/3 from 6:00am – 2:00pm.

Period of December 3 to December 9, 2017

Throughout the period covered by this look-ahead, MassDOT’s contractor for the Reconstruction of the Sumner Tunnel toll plaza will continue to progress work at the job site. Work at Sumner Tunnel will be performed during standard working hours, between 6:30 a.m. and 4:00 p.m. There will be weekend work on Sunday, December 3rd from 6:00 a.m. to 2:00 p.m.

At the Sumner Tunnel entrance this week, carpenters will be onsite Sunday, December 3 installing forms and rebar for the cast-in-place section of the median barrier and this work will require a daytime Route 1A northbound left lane closure as noted above.  Weekday work includes the paving of the section between the curbing and the median barrier, installation of the remaining curbing, stripping concrete forms, and installing the remaining asphalt patching along the new cast-in-place median barrier after the formwork is removed.  All this work is weather permitting.  


SWING LANE TIME:

MassDOT will be opening the Sumner “swing lane” from 3pm to 8pm on Sundays. This effort is to help support the Route 1A Sunday volumes that have been observed over the last several weeks.

All execution of this will be the same as has been on the weekdays and the District will continue to monitor all traffic.
