Where does that corridor (on the bridge) go?

[Phaser Two]

That might be just how the sets were set up in the soundstage. I saw the plans for the TNG set somewhere, I think, and it looked weird with the quarters, ten forward, sick bay and the bridge all connected up...
Behind it may have been the mess hall.....

Well, yeah, I imagine anyone connected with the production was answering a question about where that corridor went IRL, not where it led on the ship.

The huge windows on Voyager's messhall do not line up with anything on the back of the bridge module.

As I mentioned upthread there is no mystery that the mess hall was on Deck Two canonically. Referred to constantly as such in onscreen dialogue.

No. I mean the guy from the behind the scenes you mentioned might have meant it was a corridor leading to the Mess Hall set directly. It doesn't matter if it doesn't match the deck plan I linked.

My first guess would be straight to the shuttle and photon torpedo building slave pits, but alas, we never got a scene with someone being dragged off, begging to not be brought there, so we can't know for certain.

The same place the secondary exits from Janeway's Ready Room and the Conference room lead to...Plotspace

 

[Lakenheath 72]

We know from "Twisted" that there is a cargo hold directly behind the bridge and in a season one episode, I can't remember which one, we see a schematic of deck one and it shows a little of what lies behind the bridge.

The "Elite Force" game allows to roam the ship, but unfortunately all doors that do not lead to the scripted game path are closed.

The corridor leads to a turbo. I think Okuda said as much when they did the voyager bridge for STO

 

[Admiral Jean-Luc Picard]

From here...It looks like it leads to what should be Chakotay's office , though the layout doesn't quite match what we saw in the few times we saw his office.

I always loved how Voyager's "Deck 1" was more than just 3 rooms unlike the Ent-D.

To answer the original question: exterior shots show Deck 1 extends behind the bridge, so I always just assumed "the rest of Deck 1." I also always wondered: where's the door to seal off the bridge???
