Got a behind-the-scenes tour of the new tunnel this morning. (Looks a lot like the tunnel from Garage 1 to the Main Terminal.) Long escalators (4 at each end, but a couple at the B end won't be ready for the opening), elevators too, and 3 moving sidewalk sections in each direction.

Access at the B end will be where the mobile lounges used to dock, roughly between gates B32 and B35 - right next to California Pizza Kitchen.
