Re: Christian Science Church Center Renovation/ New Towers
That is probably the one major short-coming of the Pru. It's a missed opportunity.
In the cold winter and hot summer, I take the 111 Huntington elevators down to the Orange Level and go through the garage to the Shaw's elevator and come up into the store, avoiding the mess of tourists in the Pru, the Pru's indirect circulation (esp the crooked Back Bay Arcade) and the street-crossing.
data -- Excellent -- I like the sense of exploration offered by Gerbil Tubes and the equally interesting Mole Tunnels
Pru to Shaws is great as its not at all obvious
other good ones:
1) Sheraton lobby to Back Bay orange line platform via the tunnel under Dartmouth St.
2) Westin street-level entrance to Hynes street level entrance
3) Park Street Red or Green Line platform to Lobby of the downtown Hyatt Regency and back
a) via the elevator to the Lafayette Corporate Center Parking;
b) hallway to Macy's;
c) across the Macy's floor;
d) and then the entrance to the DTX Concourse;
e) the DTX platforms;
f) and the light in the end of the tunnel to Park Street
although I recommend that the inexperienced spelunker take the route the other-way first
By the way -- Singapore while having only a few Gerbil Tubes has many many underground links (Mole Tunnels) between buildings, and buildings and the transit system
Another place with a lot of pedestrian tunnels is the DC metro area including the DC Metro itself. I have traveled from Alewife to the Crystal City Marriott and back without coming out into a open area without at least a roof over a platform (South Station Boston and Union Station DC)
And of course Montreal with RÉSO -- its massive underground city (a fair amount of which is above ground though connected) where you can literally walk for more than a hour without retracing your path except at nodes
