Graham sez, "Given the current building chaos for the new transport hub around Ground Zero, I thought the following might be of interest.
It's a series of photos from what appear to be the early construction work on the Beekman Street Subway in 1916/1917. I've scanned them and mapped them according to the handwritten annotations on each one.
Daunting to think about what the engineers were about to negotiate – the level of chaos already achieved in a relatively young infrastructure is impressive."
