Last Buses in the Downtown Seattle Transit Tunnel 

The predomanant reason is the Convention Center expansion; construction has already demolished the former Convention Place Station and is now about to eclipse the northern exit of the tunnel. Expanded Link headways are not a factor yet, but will be eventually.

CookieGuru I alway remember that one year I was living in Seattle and still remember the bus tunnel and the interesting Convention Place Station. I first thought it was a bus depot, and it was because when I first came to Seattle, was early 2007 and the tunnel was being retrofitted while the light rail was under construction. The tunnel was opened in late 2007 and back then I remembered when taking the Sound Transit 550 from Bellevue into Seattle as the bus entered the tunnel, from I90 you could even see the T-MOBILE and Century Link stadiums all together and it feels so good to remember those days. Sadly as I had to return to Orlando Florida in 2008, wasn't able to ever ride the Link Light Rail and to see what would be like riding inside the tunnel with the buses and trains. I guess the bus tunnel wasn't meant to be a permanent solution to the Seattle traffic, but now is about to get even worse with over 800 buses running 2nd, 3rd and 4th Avenue. Just a few routes on 5th Avenue? I mean... Good luck with the traffic mayhem! 😱

Light Rail Trains Only in Downtown Seattle Transit Tunnel

The Breda ran diesel since there's only one OCS wire in the tunnel now
