Sept. 14 project update: Photos of progress inside the tunnel

Posted on Sep 14 2017 4:57 PM

Many different elements of work must be completed before the SR 99 tunnel is ready for traffic. A previous program spotlight went into these areas of activity in detail. The linear distances of completed work are tracked on the progress tracker, which we are updating monthly (look for an update to the numbers soon). 

But numbers only tell part of the story. This photo slideshow takes you inside the tunnel to see the recent progress being made beneath downtown Seattle.

Drivers on the viaduct may have caught a glimpse of the recent transformation of the launch pit where Bertha began her journey (see the final photo in the slideshow). This summer, crews working for Seattle Tunnel Partners have been busy transforming the pit into the section of tunnel that will connect the bored tunnel to the SR 99 roadway near the stadiums. We will go more in-depth on this pivotal section of the tunnel in a future program spotlight.
