I can confirm the following method has worked 3 times for me:

1. Walk up to the exit doorway from the shaft.

2. Enter crouch position

3. Start sprinting at the doorway (of course this is just you sprinting in place while in crouch)

4. Jiggle mouse left and right quickly

5. Without stopping any of the above actions, exit crouch mode back to standing

You should get teleported to just outside in the hallway. Like I said this worked three times for me. Step 4 MAY be unnecessary I don't know. Please let us know if this worked for you!
