Finding Entrances to Seattle's Transit Tunnel

I've lived in Seattle for over a year-and-a-half now, and I've taken the 194 bus from downtown to the airport several times, but each time I feel like finding where to pick up the 194 is going to be a craps-shoot. Sometimes it's above ground, and I can pick it up on 2nd. But sometimes it's in the transit tunnel, and I haven't used the tunnel enough to know where the entrances are. The last time I took the 194, I did enough advance research to find that I should catch it in the tunnel... only to discover that the tunnel was closed because of a fire. So I ran around with my suitcase trying to find an above-ground stop nearby (since Metro Transit folks didn't post any guidance). Aarrgh! Makes me miss Chicago.

Anyhow, I just found this nice map of the Downtown Seattle Transit Tunnel, and thought I'd post a link to it in case other people out there are trying to figure out where the tunnel stops are and how to get into them.
