After many comments and more digging, and a revised webpage by Metro, here’s what I think we know:
- The streetcar cannot return until the trolley barn is rebuilt, which is probably about mid-2009.
- Whether it opens or not at that time will depend largely on the fate of the Alaskan Way viaduct. If they’re going to have to shut the thing down anyway for construction in 2010, it makes little sense to run it for a few months.
Sorry for all the confusion.
