As of today, MassDOT crews as a safety measure have completed installation of redundant support straps on all of the approximately 25,000 fixtures in the Central Artery tunnels. This system was developed as an interim, 3-5 year solution to the light corrosion issues while engineers evaluate options for a long-term solution.
On July 14, a MassDOT engineer observed a light fixture out of alignment with the clips on the right side of the light not secured. The fixture was removed immediately and on July 15 re-installed with all new stainless steel clips. In addition, two high-strength straps were installed as a redundant support measure.
MassDOT crews had already begun the process of installing the redundant support straps on all of the approximately 25,000 tunnel light fixtures at the time of the July 14 discovery.
Following the July 14 discovery, Secretary Mullan ordered an acceleration of the installation of the redundant support fix for all fixtures. The intensified installation effort added outside contractors to the in house crews already working on this issue.
The Secretary had committed to completion of the redundant system installation by early August. To achieve this aggressive schedule, MassDOT mobilized additional lifts and electricians. While the crews worked throughout the tunnel system, an early emphasis was placed on the ramps and entry portal areas.
We thank commuters for their patience during the lane restrictions in non-peak traffic hours to support this work.
The MassDOT Tunnel Safety page on the web provides the latest information about ongoing steps to ensure the tunnel system remains safe.
