X-men two had a scene in there when the students were escaping from the Xavier School.
A section of that tunnel still remains and it curves from that spot under Cosmo (shown in the picture), under the old Greyhound Bus yard block (possibly the future location of the Art Gallery) to roughly the intersection of Dunsmuir & Cambie where it abuts the SkyTrain Dunsmuir Tunnel.
Its my understanding that even though this tunnel is mostly empty and unused (except for scary film shoots), it still needs to have some access doors for annual inspections. I suspect that there will be an unmarked door in the Cosmo parking basement to allow access to the remains of the tunnel.
Whenever the old Greyhound Bus yard block gets dug up, the tunnel under that property will be removed too, so there will likely only be a sliver of tunnel left under Beatty St after both sides of the 600 block are finished construction. For that remaining piece of tunnel, I think it will be filled with sand & sealed up.
