The Downtown transit tunnel (better known as the Bus tunnel). It was built for both buses and light rail, however it only hosted buses for the two decades of operation. Shared buses and trains only lasted for 10 years. A couple of years ago the buses were kicked out of the tunnel and it only services light rail now.

To my knowledge it has never serviced freight, only transit.

I aim to keep calling it the Bus tunnel—even though the transit authorities are keen on changing it—and I hope fellow Seattlites keep the name alive just for the pure quirkiness of the concept.

Go through the Bus tunnel and Ride the SLUT.[1]

That was a horrible hack that was understood at the time to be unworkable. Much ink was spilled in The Stranger about it.

I really wish the link stopped at the old 9th Ave stop to connect with busses

Less now that I've moved out of premiere on line, but still

Used to be, not anymore
