Why would this be trespassing/why would security come over? All you're doing is going to the top of a garage and taking pictures, no?

I hadn't even thought of this before, but there is currently no Chelsea St Bridge? Or is this being assembled next to the existing bridge?
The current Chelsea Street bridge is a single-leaf Bascule bridge, similar in design to this image. This issue is age, and more important, width. The existing bridge is too narrow to accommodate larger tankers, and the narrow channel is a navigation hazard. The new brige will offer a channel 2x as wide.
The process to replace involves the construction we see now (new towers, and a new truss to carry the the road-surface that will lift in one piece to the height of the towers). In a few months, the old bridge will be raised one last time; they'll remove the concrete counterweight (on the East Boston side), lower the bridge, pull the pins, slide a barge underneath it, jack it up, and float it away for deconstruction.
