TRAFFIC CAMS, WEATHER, TRANSIT: Thursday watch; 99 tunnel reopens after power-outage closure; update: why it happened

8:00 AM: The 99 tunnel is closed both ways because of a power outage.

8:20 AM: WSDOT has no estimate for reopening.

9:09 AM: Don’t even try to head toward downtown (unless it’s by bike or Water Taxi). One reader tried and finally gave up after little progress: “All roads leading in are at a standstill.”

9:23 AM: We haven’t heard a cause for the outage but for the record, here’s its footprint, from the City Light outage map, where it’s listed as 167 customers despite the outage zone’s extensive sprawl:

9:49 AM: Note that 99 access is closed far before the tunnel – for example, the ramp from the eastbound, West Seattle Bridge, and also to the south, SDOT just tweeted: “NB SR 99 is closed north of S Idaho St. All vehicles must exit at S Spokane St.” The main problem for the tunnel, per an AlertSeattle message, is that the outage is affecting its ventilation.

9:56 AM: City Light map shows most of the outage has just been resolved. We’re watching to see how soon the tunnel will reopen and will continue updating here until resolved.

10:30 AM: Still closed.

10:47 AM: WSDOT has just announced that the tunnel has reopened.

11:51 AM: We are following up on some questions raised by this. For the simple one – what caused the outage – SCL spokesperson Jenn Strang says it was “a wire that came down at 4th S and S Hanford this morning.”

1:05 PM: We also asked WSDOT about why the tunnel didn’t have backup systems. Spokesperson RB McKeon said, “There is redundancy in the system and we would normally receive power from the north end. That switch gear has failed and although our emergency generators kicked on, they are not designed to run the ventilation and some of the other systems.” McKeon added that “… we are also in touch with the manufacturer of our switch gear and have asked them for an assessment and recommendations. We are not aware of any other occasion where this has occurred.”

Earlier:

6:03 AM: Good morning! It’s Thursday, November 20, 2025.

WEATHER + SUNRISE/SUNSET

The forecast for today: Chance of more rain, then cloudy, eventually clearing, high in the low 50s. Sunrise will be at 7:22 am; sunset will be at 4:27 pm.

    WSB. With the humps/cushions in does SDOT ever gather information from SPD/neighbors to find out if they’re actually working to slow traffic-and worth the money spent installing? 

  • Ray November 20, 2025 (7:45 am)

    Avoid 99N if you can, traffic is at a standstill 

  • Chris November 20, 2025 (7:45 am)

    99 is closed going north 

  • Erika November 20, 2025 (7:50 am)

    99 tunnel closed

  • Gande pwds November 20, 2025 (7:51 am)

    Does anyone know why Aurora tunnel is closed this morning?

  • JTinWS November 20, 2025 (7:52 am)

    Whoa, SR-99 tunnel is closed, at least northbound, as of 7:50. Good day to WFH or bike if possible!The traffic camera near the southern portal into it shows the digital sign saying it’s closed to traffic and all must exit! Google maps will also not route you on it right now. Wonder what happened.

  • Ray November 20, 2025 (7:57 am)

    99N tunnel is closed 

  • Canton November 20, 2025 (8:08 am)

    Looks like 99 tunnel is closed in both directions due to power outage. The commute is gridlocked…

  • Kristina D November 20, 2025 (8:22 am)

    I’m on a C headed downtown and our driver just announced we are being rerouted due to a major power outage from Spokane to downtown Seattle, affecting (among other things) the tunnel and causing it to be closed. 

    • DC November 20, 2025 (8:54 am)

      You’re lucky to have gotten on after the reroute. Ive been stuck on the H on 99N for 50 minutes… 

  • Calamity November 20, 2025 (9:00 am)

    Caught up in the traffic on the bridge. I’m on the bus and we’re rerouting. Weirdly, my bus doesn’t even go into a tunnel ever, I feel like transit should be allowed to go if not going through the tunnel. 

    • Derp November 20, 2025 (9:31 am)

      I don’t think there are any routes that go thru the tunnel. 

      • Little One November 20, 2025 (10:02 am)

        I think traffic is so backed up that it’s affecting any other routes in the area, since usual 99 traffic needs to reroute. Hence why buses are also trying to adjust.

  • Sukie November 20, 2025 (9:09 am)

    Its’s still total gridlock on the bridge now! 

  • Lola November 20, 2025 (9:10 am)

    Over here is Georgetown we have power just massive traffic clogging all the road.  7th & Lucille is mad traffic and cars are at a standstill.  My son said 4th Ave is the same, Be careful out there folks. 

  • Foop November 20, 2025 (9:38 am)

    That light rail would be amazing about now.

    • my two cents November 20, 2025 (9:54 am)

      While I agree with the sentiment, rail could potentially be impacted by electrical issues.  Also, should be noted that this past week the light rail was shut down for maintenance issues – so it is not running 24 x 7.

    • Kyle November 20, 2025 (10:02 am)

      Good thing the light rail never has power outages.

    • 935 November 20, 2025 (10:43 am)

      Light rail loses power more often than the tunnel does.

      • K November 20, 2025 (10:53 am)

        And when it does you can take the bus.  Having more than one form of transportation is really helpful.  

        • Foop November 20, 2025 (12:50 pm)

          Someone gets it.

  • lightrail November 20, 2025 (9:50 am)

    Dang, it sure would be nice to have light rail out of West Seattle to avoid traffic issues.

    • Julian November 20, 2025 (12:27 pm)

      Just give it another… 8 years and we might have something on track to be completed.

    • Dr Wu November 20, 2025 (5:58 pm)

      I hope this is reminder to be prepared when the electrical grid shuts down. Light rail will not save you. 

  • Wes November 20, 2025 (9:57 am)

    I wonder if it has anything to do with copper theft.

  • Daniel November 20, 2025 (10:18 am)

    I’m on the bridge as I type this from my commuter bus. I left N Admiral around 8:30 and I’m still on the bridge. This is terrible

  • Fed Up November 20, 2025 (10:31 am)

    So why do we need to have power on in a tunnel? oh yeah, the city can’t rob us with the tolling.  I mean all cars have lights right?  so seriously why do we need power?  

    • WSB November 20, 2025 (10:42 am)

      Well, for one, it would be awfully dark. An unlit underground tunnel would likely make the lights-out West Seattle Bridge look like a summer midday. But underground, you need air as well as light; AlertSeattle’s one and only message about this so far says the outage affected the ventilation. Also, please note, the city has nothing to do with the tunnel tolling. It is a state facility (WSDOT) and that’s who operates it, including toll collection – TR

    • Churro Strength November 20, 2025 (11:19 am)

      Are you serious? You don’t think an underground tunnel with no lights isn’t a huge safety issue? Is this a joke?

    • Anne November 20, 2025 (11:22 am)

      Are you serious? Aside from lights – probably an even bigger issue-VENTILATION!!

  • Robert November 20, 2025 (10:32 am)

    This is insane. 1.5 hours just to get to the top of the bridge.

  • Rachel November 20, 2025 (10:34 am)

    Why were there NO police ANYWHERE helping relieve/reroute the traffic??!!! It took me over 3 hours to get from Highland Park to work in Ballard.

    • k November 20, 2025 (7:20 pm)

      Because it’s not their job?  Why weren’t librarians out there making your commute easier?  Or park rangers?  What could a cop have done that the traffic cones and signage didn’t accomplish?  It’s an electrical issue, not a public safety one.  Are you one of those people who calls 911 when McDonal’s runs out of nuggets?  Police are not the answer to every problem.  

      • Rachel November 21, 2025 (8:44 am)

        The SPD has a Traffic Enforcement Unit, and I do believe that IS there job. There were no cones or signage helping anyone get to work yesterday. There are certainly plenty of cops directing traffic during sporting event. Also, get over yourself.

        • k November 21, 2025 (12:03 pm)

          What traffic rules weren’t being enforced, that needed to be?  Police direct traffic after games to override existing traffic controls.  The cones and signs did exactly that: they told people the tunnel was closed and where to exit.  People got where they were going, while following the rules.  It was just slow.  Terrible traffic does not require enforcement, it requires patience, which is your problem to solve, not SPD’s.  

  • colleena November 20, 2025 (10:53 am)

    And insanely significant issues with the upstairs bridge. Thirty five minutes from Seaview just to get to the top of the bridge eastbound. If you have other options, highly recommend —

  • Marcus November 20, 2025 (10:56 am)

    Three Things:1) power outages happen!2) traffic happens!3) nice bump!

  • Brian November 20, 2025 (12:59 pm)

    With an underground tunnel it would be nice to have underground power, ya think.

    • bolo November 20, 2025 (2:41 pm)

      Meaning what? Geothermal power?

  • aRF November 20, 2025 (1:01 pm)

    1 1/2 hours to get from West Seattle to Capital Hill this morning leaving at 7:35am.

  • Mark Schletty November 20, 2025 (4:06 pm)

    Back up generators dont run the ventilation system. Why not? That is a critical failure on the part of WSDOT.  It completely  undermines my trust in using the tunnel. A shut down tunnel full of vehicles combined with no ventilation is a formula for many deaths. This situation has to be corrected immediately. 

    • wscommuter November 20, 2025 (8:34 pm)

      Then don’t use the tunnel.  Stick to the things you do “trust”.  Easy-peasy.

    • bolo November 21, 2025 (10:55 am)

      Next time you travel thru the tunnel, please notice the numerous emergency exit doors along the sides.
      But next time the power goes out while you are driving in the tunnel, just continue driving out of it. Presumably they close the entrances when that happens, not the exits.

      “The tunnel has 15 emergency refuge areas located every 650 feet (200 m) with escape routes that lead to the north and south portals. Variable message signs and emergency phones are also located throughout the entire tunnel.[9] The tunnel is monitored by over 300 security cameras that are fed into a WSDOT traffic control center in Shoreline that can dispatch incident response teams.[8][11] In the event of a fire, a set of fiber optic cables in the ceiling would sense heat and activate sprinklers.[12] A set of large fans located in the two portal operations buildings would then force smoke out through a set of 40-foot (12 m) ventilation shafts.[8][13] The tunnel also has repeaters for cell phone and FM radio service; WSDOT can override the latter for emergency broadcasts.[6][11]”

  • John November 20, 2025 (5:10 pm)

    Does anyone know why 99 was shutdown all the way south of the WS Bridge? I made it to 4th Ave Exit in 62 minutes, sat there for a couple turns of the light without moving (since 4th and 1st were stopped), and then decided to come home the back way (but of course hit the 1st ave bridge just as it was going up…). Leaving 99 open to exit at the stadiums before the tunnel probably could have helped a little bit in shuttle traffic from the south to downtown. 

    • WSB November 20, 2025 (5:54 pm)

      Because they shut down access in a variety of directions, not just right before the tunnel. (On the bridge, for example, they closed the ramp to 99, even though it can be uded to access and exit 99 before the tunnel.(

  • Are we part of this City? November 20, 2025 (6:22 pm)

    Once again, the rest of Seattle and SDOT are treating us like “those people over there.” It’s so wrong that they left us to twist for nearly four hours this morning. It’s a huge public safety threat. Hopefully no one needed life saving medical attention. It’s also wrong that the back up systems are so grossly ineffective. It’s wrong that that some bureaucrat thought it was ok to cut off one of four access points to downtown when they took our access away to the stadium/downtown exits on 99 north (a road that would have also provided a transit byway that would have expedited all transit routes dramatically and provided a lane for emergency vehicles). It’s wrong that our light rail expansion has been hijacked by urbanists that think they can spend insane amounts of money and their over ambitious plans are seriously threatening the entire project. Shame on the people that think that light rail can and should be replaced with more buses. And wow, what the what were the people thinking that proposed not replacing the viaduct at all, in favor on “surface options”. It is unsafe for the status quo to be maintained. I hope so real learning takes place here, starting with SDOT leadership finally embracing the idea that job is to get people moving not create so much pain that people are forced to adopt a modal shift to a system not yet reliable (buses), not yet built (light rail) or not equitable (bikes). And with Katie Wilson’s incoming administration getting to learn on the job, rather than electing someone actually qualified, there really isn’t any hope for our “leaders” to learn from these epic failures. Today’s disaster was predictable, preventable, avoidable, and incredibly dangerous. Please do your jobs. 

    • Jake November 20, 2025 (7:52 pm)

      Who is mayor today? Oh yeah that’s Bruce still. Katie Wilson’s entire experience is around transit, this comment makes no sense.

    • Confused November 20, 2025 (10:41 pm)

      Are you really that out of touch? SDOT has their own issues but they have nothing to do with the tunnel that is WSDOT. State highway state agency. If you want to blame a city agency then how about City light who 7 months after the lights burned out still have not fixed the over 30 streetlights from the tunnel across Harbor Island and down to Terminal 5. If you want to blame SDOT then blame them for the continued lack of fixing or even repainting roads. 

    • aa November 21, 2025 (11:12 am)

      I hate to break it to this person, the power outage and traffic meltdown did not just happen to West Seattle. Historically speaking, it is more common for West Seattle to want to separate from the rest of the city rather than your fantasy that the city and SDOT don’t about WS.

  • George November 21, 2025 (12:03 am)

    I found a nice shortcut this morning. I drove south on 509 and then north on 405. I probably saved over an hour in traffic. I thank the lucky stars that I decided not to proceed up the ramp to the bridge!

  • Eddie November 21, 2025 (6:58 am)

    I had a wonderful bike ride and wondered why all the cars were so stacked up.

  • Kathy November 21, 2025 (11:31 am)

    I wonder what percentage of the single occupancy cars in this traffic jam had no other means to get to their destination and what percentage chose that method for the sake of convenience? When I started bike commuting in 1996, even then it was a more dependable way to get to my destination in a predictable amount of time as opposed to sitting in a traffic jam on the viaduct. Since that time public transportation (Metro buses) has been increasingly held hostage in traffic jams. Since the pandemic, Metro has struggled to recover and almost every day I get a notice in my email that my Metro routes have been cancelled or delayed due to traffic issues.  A bike can take you a few miles from West Seattle to the SODO light rail station that has lockers to store your bike so you can ride light rail that is not impacted by traffic. A bike can be put on the Water Taxi to get out of West Seattle. Ebikes, cargo bikes and appropriate rain gear make this kind of commute even more practical. As you sit for hours fuming in your single occupancy vehicle, you could humbly remember that you are the traffic.
