SR-99, Seattle, WA 98101
Bye forever, viaduct!
The boombox scene was filmed in LA, but there’s plenty to see here
As Seattle heads into a three-week traffic, there are some added transit options—and missed opportunities
What’s happening right now—and what’s happening in through 2023?
Watch the roadway being constructed
The tunnel’s on track to open in 2019
Travel the tunnel’s two-mile span a couple of years early.
With planned pedestrian and bike improvements
Don’t plan on taking 99
RIP forever, Bertha.
Sped up in a time-lapse video, it’s exciting—and a little satisfying—watching the machine come apart. Watch seven weeks of disassembly in one minute.
The just-completed South Dearborn Street Off-Ramp Bridge won’t carry cars for a long while—but it’s notable for its earthquake-safety technology.
Late Wednesday, crews finished removing wall braces standing between tunnel-boring machine Bertha and the disassembly pit.
In case you missed the big moment
We heard a lot of things about what would happen with the tunnel project—and a many of those stories didn’t come true.
After nearly four years, Bertha has finished digging SR 99 tunnel.
After more than three years of drilling, Bertha’s journey is coming to an end on Tuesday—and the big moment is being livestreamed.
Bertha won’t see daylight this week, but the tunnel boring machine is nearing the finish line.
These days, Bertha seems to get going a lot faster than expected
The tunnel boring machine is actually staying on schedule these days
As a reminder, Bertha was originally supposed to be surface in South Lake Union in October 2014 and the tunnel was supposed to open by the end of 2015.
Last week we found out WSDOT and Seattle Tunnel Partners were going to need to close the Alaskan Way viaduct for two weeks while Bertha dug underneath. Friday they announced that the official start date for that two-week closure will be April 29.
