What is this building used for?

[Greg Bernhardt]

I was in Boston this past weekend and noticed this building. It has no doors. It is located directly above the "big dig" and has security cameras lined around the outside. Any ideas what it houses? It's on the Congress and Atlantic intersection.

Ventilation for the tunnel?

Based on the information provided, it is difficult to determine the exact purpose of this building without further investigation. However, based on its location above the "big dig" and the presence of security cameras, it is possible that it serves as a control center for monitoring and managing traffic and construction activities in the area. It could also potentially house equipment or machinery related to the ongoing construction project. Without access to the building or more information, it is difficult to make a definitive conclusion. Further research or inquiries with local authorities may provide more insight into the building's purpose.
