I don't recall who, exactly, gave the order to close the tunnels but IIRC, all of the south side tunnels were locked in late 2001. In the years since, however, all of the tunnels were re-opened except for the T-4 to T-5 tunnel. With AS now in T-6, I'd vote to re-open the T-4 tunnel.
Last time I did an AA to AS connection (with tons of time), my AS bus decided to go to the AE terminal first because of some people in great danger of missing their connection (with no AE bus in sight). While it didn't make me late, it really made me want to just be able to walk over to T6 on my timeline and not be at the mercy of a bus system.
