At a press conference yesterday, Metro, Sound Transit, and SDOT released their initial plans for the post-bus tunnel era. On March 23, Sound Transit will be the sole operator of transit service in the Downtown Seattle Transit Tunnel (DSTT), and will run only Link light rail trains through it.
Metro and Sound Transit buses that ran through the tunnel will now run on surface streets. According to Metro, 830 daily trips will move from the tunnel to the streets. Those trips will still enjoy their own right of way through most of downtown, though the impact to reliability remains to be seen.
Some Metro routes, including workhorses like the 40 and 120, will add additional trips thanks to funds from the Seattle Transportation Benefit District (STBD). We’ll cover the changes to those routes, and a systemwide service restructure, in a later post.
Link riders will experience several major changes. Link will become more reliable and frequent, with consistent, six-minute headways. Seven routes, including Sound Transit’s high-ridership Route 550, will move from the tunnel to the surface.
