99 TUNNEL: Southbound closure added next weekend for repairs

(WSDOT photo, February 14)

The weekly SDOT lookahead (PDF), which often brings first word of key WSDOT closures too, arrived with news of an added Highway 99 tunnel closure described as being for “repairs,” 10 pm next Friday (February 28) to 8 am next Saturday (February 29). We asked WSDOT spokesperson Laura Newborn if the repairs are related to the water leak from the southbound tunnel’s ceiling. She said yes, elaborating;

The purpose of the closure purpose is two-fold.

1. For the tunnel contractor to repair and reseal a small grout-port where water is leaking (the tunnel is under warranty).

2. To complete regularly scheduled tunnel maintenance from Friday, Feb. 14 as crews spent maintenance time creating a temporary repair for the water leak.

We want to emphasize this is considered a minor leak with a straightforward repair plan. The tunnel remains very safe for driving.

The repairs involve re-grouting the area near a grout port and resealing the grout port. During construction, these types of ports were used to add grout to the area between the ground and the outside of the tunnel wall.

Again, that’s next Friday night, NOT tonight. The NB tunnel, meantime, has a regular maintenance closure March 13 (10 pm)-14 (8 am).

HIGHWAY 99: Next tunnel closure, and an anniversary

Two Highway 99 notes:

NEXT TUNNEL CLOSURE: Looking ahead beyond whatever the weather brings this week, the next Highway 99 tunnel maintenance closure is set for 10 pm next Friday to 8 am next Saturday (January 17-18) – northbound only this time.

ONE YEAR AGO TODAY: January 12, 2019, was the first day without the Alaskan Way Viaduct. As we noted very early that day, the last vehicles were cleared just after midnight.

“Realign 99” ensued; the tunnel opened late the night of February 3rd, a day and a hal after a gala dedication ceremony – and with a snow day looming.

TUNNEL-MACHINE LAWSUIT: State wins

(2015 tunnel-machine-repair site photo by Long Bach Nguyen)

Six years ago, right about this time of year, the Highway 99 tunnel machine broke down, and tunneling was on hold for more than two years. The state sued the contractor, Seattle Tunnel Partners, seeking $57 million. Today, a jury in Thurston County ruled in favor of the state, saying STP indeed should pay that sum. As noted in this Seattle Times report, the state claimed the stall was STP’s fault, while STP claimed it was the state’s fault. WSDOT sent this statement from state Secretary of Transportation Roger Millar:

“WSDOT is committed to protecting taxpayer money. Knowing the risks associated with tunneling beneath downtown Seattle, we structured our contract with Seattle Tunnel Partners in a way that placed the risks of tunneling on the contractor. We have remained steadfast in our belief that Seattle Tunnel Partners was responsible for the costs of fixing the broken tunneling machine and paying damages for completing the tunnel three years late. We believe the jury got it right and we are grateful for their patience and dedication to ensuring a fair outcome to this case. Since an appeal is possible, we cannot yet say what will become of the damages awarded by the jury.”

If you’re interested in more backstory, here’s a WSDOT infosheet (PDF) also sent today.

FOLLOWUP: ‘Tunnel usage remains high and exceeds forecasts’

One month ago today, the Highway 99 tunnel became a tolled roadway, after 7 months free of charge. Pre-tolling, local transportation authorities projected that up to 50 percent of would-be tunnel users would start avoiding it when tolling began. A few days in, they said the avoidance – officially known as “diversion” – was less than they had expected. Now they’ve crunched more numbers and report that trend contnues. The details are in this post on the WSDOT Blog today, which declares “tunnel usage remains high and exceeds forecasts”:

Prior to the start of tolling on Nov. 9, 2019, about 77,000 vehicles used the tunnel on average weekdays. Since tolling started, roughly 20,000 fewer vehicles are using the tunnel – about 26% less. This drop is less than the 35% to 50% predicted. However, the story is more nuanced. Peak travel volumes in the tunnel remain high. Mid-day volumes are lower, likely due to less crowding on city streets.

The WSDOT report goes into analysis of how travel time has been affected, including buses – among the sample routes mentioned, WSDOT says the 120 stayed the same in the morning, but took “less than 2 minutes longer” in the pm. Also mentioned: “Roughly 80% of vehicles in the tunnel are using either a Good To Go! pass or Pay By Plate.” (If you don’t, you get a bill by mail, sent to wherever your car is registered to.)

TUNNEL TOLLING: First 3 days of data show ‘diversion’ not as bad as it could have been

So how many people are dodging the Highway 99 tunnel now that tolls are being charged? We’re just out of a downtown briefing where WSDOT and SDOT reps shared the answer, which is basically: Not as much as feared. They cited Tuesday/Wednesday/Thursday data, saying that over those three days, tunnel volume averaged no more than 30 percent below pre-toll levels. (There had been projections suggesting up to 50 percent “diversion.”) Alaskan Way, accessible from the pre-tunnel Dearborn exit from NB 99, had somewhat higher usage, but 1st and 4th were “typical.”

Too soon to declare a definitive trend, cautioned WSDOT’s toll-operations director Ed Barry and SDOT’s downtown-mobility director Heather Marx, but that’s what they have so far. About 75% of those going through the tunnel had eiiher a Good To Go pass or account, so the other 25 percent will be getting bills in the mail. (If you’re waiting for the system upgrade that will allow you to use GTG without putting $30 in the account first, that’s not going to be available until next year. We recorded the briefing/Q&A, held in SDOT’s Traffic Management Center, on video, and will add it after we get back to HQ.

>

ADDED 5:44 PM: Above, video of the entire briefing/Q&A, which lasted just under 15 minutes. Side note: Pre-briefing, we asked Marx about the pre-tunnel bus lane, the length of which was tweaked some weeks back. She said it’s “working exactly as planned” and that its importance will increase even further when buses switch to Alaskan Way, which she said is expected to happen in January.

LAST REMINDER: Highway 99 tunnel tolls start Saturday

That’s a WSDOT crew uncovering one of the signs south of the northbound Highway 99 tunnel last night. By 5 am, all signs in both directions will be uncovered, because that’s when tolling begins – though it’ll be a little later on the northbound side, since that’s scheduled for a maintenance closure 10 pm tonight until 8 am tomorrow. If you’re still not entirely sure how tolling will work, here’s a WSDOT video:

And here’s the chart of what you’ll pay and when:

If you don’t have a Good To Go sticker pass, you can still get one, but they’re not free any more. You can also open a Good To Go account without a sticker – that’ll cost you an extra quarter each time you’re tolled if your car is registered to the account. Or if you skip Good To Go altogether, every time you take a tolled trip, you’ll pay $2 extra and get a bill via postal mail.

1 WEEK TO GO: Ready for Highway 99 tunnel tolling?

One week from today, seven months of toll-free Highway 99 tunnel travel will end. The tolls vary by daypart – here’s the chart:

Those are the rates you’ll pay if you have a Good To Go! pass and account. If you have an account but no sticker, it’s a quarter more. If you have neither, you’ll get a bill in the mail (your plate is read at tunnel’s end) and it’ll be $2 more. If you don’t have a GTG sticker yet, WSDOT is still offering them free.

HIGHWAY 99: Tolling in 2 weeks; Viaduct remainders

Two Highway 99 notes tonight:

(That’s about to change! WSB photo from August)

TUNNEL TOLLING IN 2 WEEKS: Saturday, November 9th, is now just two weeks away, and that’s the day WSDOT plans to start tolling the tunnel, nine months after it opened. Toll rates are here – extra charges if you don’t have a Good To Go! sticker pass and account, as explained here. There’s still time to get the sticker free by going here.

VIADUCT REMAINDERS: If you thought the Alaskan Way Viaduct demolition was complete – not so, explains WSDOT here. [corrected link]

NEXT WEEKEND: NB Highway 99 closure

Looking ahead to next weekend, one closure alert: WSDOT plans to close northbound Highway 99 all the way from the West Seattle Bridge to the north end of the tunnel, 11 pm Friday (October 11th) to 4 am Monday (October 14th).

Highway 99 tunnel toll-sign test tomorrow

(WSB photo from Monday)

If you’re using the Highway 99 tunnel tomorrow, you might notice the tolling signs that currently say FREE will instead display symbols. Just a test, WSDOT spokesperson Laura Newborn says – tolling really won’t start until November 9th, as announced back on Monday. Depending on the time of day, here’s what the signage will show tomorrow (and other testing times) in the Good To Go (GTG) and Pay By Mail (PBM) displays:

Time of Day GTG PBM
5:30 a.m. $!.)) $#.))
6 a.m. to 7 a.m. $!.@% $#.@%
7 a.m. to 9 a.m. $!.%) $#.%)

6 p.m. to 11 p.m. $!.@% $#.@%
11 p.m. to 11:30 p.m. $!.)) $#.))

Newborn says 4,000 more people have signed up for free GTG sticker passes since Monday’s announcement – you can do it by going to 99tunnel.com.

UPDATE: Start date announced for Highway 99 tunnel tolling, and news of a bus plan on the horizon

11:02 AM: Today the signage for the Highway 99 tunnel says FREE, but not for much longer. At a media briefing near the tunnel’s north end, WSDOT has just announced tolling will begin November 9. Details to come.

11:23 AM: The briefing is wrapping up and there’s been another announcement of sorts: SDOT’s Heather Marx says they are about to announce a plan for addressing the West Seattle bus slowdowns. Plus they’ll have a plan for the Dearborn demolition of the remaining Alaskan Way Viaduct demolition. The reroute details are almost ready to go.

11:46 AM: New since the announcement:

A few other notes from the briefing: If you already have a Good To Go! sticker, you’re set. If not, get one – you can do it online, free if you act fast.

(Good To Go sticker, held by WSDOT’s Patty Rubstello)

Otherwise, if you take the tunnel once tolling begins but don’t have one, you’ll get a bill in the mail, at a higher rate (as is the case now with other WSDOT facilities that use GTG such as the 520 bridge across Lake Washington). With GTG, as set by the state Transportation Commission last year, the tolls will range from $1 to $2.25 depending on time of day. The tolls are meant to raise $200 million of the tunnel’s cost.

Another note from the briefing – a few new SDOT catchphrases detected. For example, Marx (who lives in West Seattle) repeatedly stressed that your “commute decision is a community decision.” Also, she mentioned a new program that’ll involve large employers, to be called Flip Your Trip. Also, a repeated reminder that years of the “Seattle Squeeze” remain.

The WSDOT and SDOT reps acknowledge – as they have all along – that the start of tolling could lead to a significant amount of “diversion” – people avoiding the tunnel – possibly up to 50 percent at the start. Currently they say the tunnel is up to about 80,000 vehicles a day.

When will tolling start for the Highway 99 tunnel? Announcement tomorrow

(WSB file photo)

Almost seven months after the Highway 99 tunnel opened, it’s still toll-free – but we may finally be about to learn when that will change. WSDOT has invited media to an announcement event at midday tomorrow at which it promises information about a start date. As noted on the state’s infopage, once tolling begins, “Toll rates will range from $1 to $2.25 with a Good To Go! pass depending on time of day.”

HIGHWAY 99 TUNNEL: Tolls delayed; traffic alert for NB pre-tunnel exit

Two notes today related to the Highway 99 tunnel:

TOLLS DELAYED: WSDOT confirms what was first reported by citywide media earlier today – that the tunnel tolling, originally expected to start this summer, is now delayed until fall. The state is switching vendors for its tolling system and won’t be ready to go this summer as originally planned.

TRAFFIC ALERT: Last night, we reported that WSDOT said Alaskan Way Viaduct demolition is now at the midway point and moving southward. As part of that, lane closures on surface Alaskan Way just north of the NB 99 pre-tunnel exit might back things up, spokesperson Laura Newborn warns:

At 4 a.m. on Friday, June 14, crews preparing for viaduct demolition will reduce Alaskan Way to one lane in each direction between South King and South Dearborn streets. This lane reduction will last more than a month. Narrowing the roadway is the only way for crews to safely prepare and demolish this section of viaduct. Because this section of Alaskan Way is near the SR 99 northbound off-ramp at South Dearborn, travelers may encounter backups on the northbound off-ramp and, potentially, the northbound mainline entering the tunnel.

We expect the heaviest congestion will occur during peak travel periods, special events and on weekends, when ferry traffic increases and cruise ships are in town. Travelers approaching downtown from the south should plan ahead for longer drive times and consider alternate routes or ways of getting around, including transit and the King County Water Taxi.

CLOSURE: Highway 99 tunnel closing both ways next Friday night/Saturday morning

June 2, 2019 9:43 pm
|    Comments Off on CLOSURE: Highway 99 tunnel closing both ways next Friday night/Saturday morning
 |   Highway 99 tunnel | West Seattle news | West Seattle traffic alerts

Heads up if you use the Highway 99 tunnel late night/early morning: SDOT’s advance list of upcoming closures around the city says the tunnel will be closed in both directions from 10 pm next Friday (June 7th) to 8 am Saturday (June 8th).

Using the Highway 99 tunnel? WSDOT offering free stickers you’ll need for lowest rates when tolling starts

The Highway 99 tunnel is expected to remain toll-free at least until late summer – here are the factors playing into the timeline, as presented to the Washington State Transportation Commission two weeks ago:

But WSDOT wants you to start preparing now, so starting today, it’s offering free Good to Go! sticker passes for tunnel users. If you don’t have one when tolling starts, you’ll be charged a higher toll rate, as explained in the announcement:

With a Good To Go! pass registered to an account, toll rates will range from $1 to $2.25, depending on the time of day. If drivers register their vehicle on an account, but don’t have a pass, it will cost 25 cents more per trip. Without a Good To Go! account, it will cost drivers $2 more per trip.

The sticker would normally cost $5. Be sure to order your free sticker via the instructions on this page – and also make note of the option to wait on activation (but NOT on sticker ordering) to avoid having to put money in your account in advance.

HIGHWAY 99 TRANSITION: New northbound exit ramp to downtown opens Tuesday

The next major piece of the puzzle in the viaduct-to-tunnel transition will be in place by tomorrow morning – the new exit ramp from northbound Highway 99 into the south end of downtown will be open by tomorrow morning, as just announced by WSDOT:

The end of the holiday weekend brings the start of a new way for drivers and bus riders to get to downtown Seattle from northbound State Route 99.

The new off-ramp near the sports stadiums will open for drivers in time for the morning commute Tuesday, Feb, 19.

This new exit ramp leads to a new intersection at South Dearborn Street where drivers can choose to head straight to Alaskan Way and the waterfront, or turn right to access First Avenue and downtown or SODO. This video shows what the choices look like:

In addition to being an important link for travelers, engineers and researchers hope this new ramp will provide a link to something else – earthquake-resistant bridges.

This ramp is the first in the world built with flexible metals and bendable concrete designed to sway with a strong earthquake and return to its original shape. Its innovative design has won regional and national recognition.

After the opening of the new off-ramp, some bus routes will be adjusted. Please see King County Metro’s website for additional information.

(We’ll be following up separately with Metro and SDOT about the timeline for that and for other changes such as the end of the temporary 4th Avenue bus ramp/lane from the West Seattle Bridge. *6:56 PM UPDATE* Metro says yes, buses will shift to the new ramp starting Tuesday.)

WSDOT had warned for months that the exit ramp would take another one to two weeks to finish, after the opening of the Highway 99 tunnel; the recent snow added a few days to that timeline. Without this ramp, everyone using NB 99 in the past two weeks from West Seattle or points south has had to do so without being able to exit until north of the tunnel.

HIGHWAY 99: Offramp update; Viaduct demolition plans

Two Highway 99 updates this afternoon:

(Monday afternoon view from construction-zone camera, looking south across new offramp)

REMEMBER THE RAMP? The tunnel’s been open for more than a week now, but the Dearborn/Alaskan Way offramp – to allow people traveling from West Seattle and points south to exit NB Highway 99 before the tunnel – is still under construction. The culprit, as you might expect – the snow. We asked WSDOT’s Laura Newborn today if there’s an update on the offramp’s expected opening: “There’s still weather-dependent work ahead of us. We do believe it will be next week but can’t say yet what day.”

ALASKAN WAY VIADUCT DEMOLITION: This too has been delayed a bit by the snow. WSDOT now says it’ll start later this week, at multiple spots including the Columbia/1st ramp. They’ve also added webcams focused on the Viaduct so you can watch the work.

FOLLOWUP: Highway 99 tunnel’s first true traffic day, downtown-ramp update, and more

Today was the first real test of the Highway 99 tunnel in traffic. If you weren’t among those using it – above is the next best thing, Jamie Kinney‘s dashcam video from the northbound morning commute. Below, a “live” look inside the south end of the northbound deck:

One big question remains for West Seattleites: When will that exit ramp to the south end of downtown open, so people headed northbound from here can use 99 without having to go through the tunnel? Dating back to last summer, WSDOT warned it would take up to two weeks beyond the tunnel opening to finish that ramp. Optimistic projections more recently were that it could be as little as one week – but then came the snow. We checked in today with WSDOT’s Highway 99 project spokesperson Laura Newborn, who says, “Weather definitely put the work behind on the NB off ramp Monday and Tuesday. The contractor is working today, but the bad weather could cause challenges for the crew.” And, of course, as the weather experts are warning, it’s likely not over yet. One other thing about NB 99 came up in a comment discussion today: The NB bus lane south of the tunnel. It was cut short a while back so that crews could repair a “dip” and has not been fully restored yet, but Newborn says it will extend to, and onto, the new Dearborn/Alaskan Way exit ramp, and then after the Metro routing “interim” time of up to 1 year, will also extend onto the new Alaskan Way. (The 4th Avenue temporary bus lane on the eastbound West Seattle Bridge, meantime, will be removed once buses stop using that ramp, SDOT has reiterated – again, waiting on that NB 99 exit ramp.)

West Seattle Blog editor

After a dramatic 18-year prelude, the Highway 99 tunnel’s Monday debut was upstaged, big time.

Two inches of snow overshadowed two miles of tunnel.

But before the new tunnel becomes old hat, we need to finish telling the tale of its Saturday dedication, and the memories the event unearthed.

TRAFFIC ALERT: Highway 99 tunnel now open

11:23 PM SUNDAY: It’s official – the Highway 99 tunnel is now open. The video above is by Paul Weatherman, who reports his was the first non-government vehicle to travel the northbound lanes right after they opened around 11 pm (added – full clip here); WSDOT says it’s working to get the southbound lanes open too. No toll until sometime this summer. This sign we photographed during Saturday’s dedication event will verify that for skeptics:

If you’re heading northbound on 99 from the eastbound West Seattle Bridge or from south of here, remember, no downtown exit before the tunnel for another week or so.

12:22 AM MONDAY: And now the southbound direction is open too. With this plus the snow, a unique morning commute is ahead, and we’ll be tracking it all starting at 5 am.

VIADUCT/TUNNEL TRANSITION: What you need to know about other new ramps and intersections that ARE now open

We can’t say this enough: When the Highway 99 tunnel opens – hours from now – there will be a transitional week or so during which the exit to NB 99 from the EB West Seattle Bridge is a “tunnel only” exit, because the offramp to downtown, before the tunnel, isn’t done yet. Separate from that, some new ramps/intersections HAVE just opened on both ends of the tunnel, including the one that you will use to get to SB 99 just south of the tunnel. WSDOT has just published this update that we’re reposting in its entirety:

The Feb. 4 opening of the SR 99 tunnel brings big changes to several important intersections at the tunnel’s north and south ends. New intersections can be confusing, so use the renderings below to help familiarize yourself with what you will encounter on the road. You can also preview the intersections via narrated videos.

North end of the tunnel: Harrison Street and Aurora Ave North

What’s changing:

New northbound SR 99 on-ramp
New southbound SR 99 off-ramp
Harrison Street open east-west across Aurora Avenue North
The new tunnel dives underground at Harrison Street, several blocks north of where the now-closed Battery Street Tunnel begins. The new intersection of Harrison Street and Aurora Avenue North is where the northbound on-ramp begins, and the southbound off-ramp ends. Harrison Street is now also open east-west across Aurora Avenue North.

Note: Construction begins this month on the inside lanes of Aurora Avenue North between Denny Way and Harrison Street (yellow zone at bottom). Learn more about how the North Surface Streets project is rebuilding Aurora Avenue North.

North end of the tunnel: Republican Street and Dexter Avenue North

What’s changing

New northbound SR 99 off-ramp
The intersection of Republican Street and Dexter Avenue North is where the northbound SR 99 off-ramp ends. New signals will control traffic coming off the highway. From the off-ramp drivers will be able to turn left toward Mercer Street, head straight toward South Lake Union, or turn right to head toward Denny Way. Stay alert for people using the Dexter Avenue bike lanes on both sides of the street.

South end of the tunnel: Alaskan Way, South Dearborn Street, and First Avenue South

What’s changing:

New southbound SR 99 on-ramp
New northbound SR 99 off-ramp [NOT YET OPEN]
New east-west street, South Dearborn Street
New primary path between First Avenue South and Alaskan Way
Alaskan Way extended farther south
One of the biggest changes to surface streets is at the tunnel’s south end, just west of CenturyLink field. Alaskan Way no longer ends with a jog under the viaduct onto Railroad Way South. Instead, it continues straight to a new intersection with a new road, South Dearborn Street.

South Dearborn Street is the new east-west connection between Alaskan Way and First Avenue South. This intersection connects SR 99, Alaskan Way and First Avenue. Alaskan Way continues south from this intersection toward East Marginal Way South. Railroad Way South is currently closed from First Avenue South, and when it reopens it will be a local-access-only road.

IMPORTANT NOTE: The northbound SR 99 off-ramp bridge is still under construction and will open one to two weeks after the tunnel opens.

Note: The rendering above does not show the now-closed Alaskan Way Viaduct, which sits in the yellow-highlighted work zone and will be removed section by section over the next six months.

South end of the tunnel: South Royal Brougham Way and First Avenue South

What’s changing:

New northbound SR 99 on-ramp
New southbound SR 99 off-ramp
Colorado Avenue South with two-way traffic to South Atlantic Street
Drivers who previously joined SR 99 northbound from Royal Brougham Way will find striking changes to that intersection. Where once there was a ramp to the viaduct, now there are two ramps to the tunnel. This is where southbound drivers in the tunnel will exit to reach SODO, the stadiums, and I-90 and I-5. This is also where drivers coming from I-90 or the stadiums will enter the tunnel for northbound SR 99.

Note: A shared-use path along Colorado Avenue South will be built in a future phase of the project.

South end of the tunnel: South Atlantic Street and Colorado Avenue South

What’s changing:

New surface-street connection to Alaskan Way South
Colorado Avenue South with two-way traffic to Royal Brougham Way South
The changes around South Atlantic Street are less drastic but still worth knowing. The Atlantic Street overpass over SR 99 is now a complete connection to Alaskan Way (to the north) and East Marginal Way South (to the south). You can now reach both via South Atlantic Street by taking the ramp labeled below.

Colorado Avenue South (previously called East Frontage Road) is now a two-way street, providing a north and south route between South Atlantic Street and SR 99 on- and off-ramps. A common path from SR 99 southbound to reach I-90 will be to take Colorado Avenue south, then take a left turn onto South Atlantic Street.

Note: At tunnel opening South Atlantic Street does not pass beneath the SR 99 overpass to Alaskan Way South. That connection will open later in winter/spring 2019.

Again, no specific time yet for the actual tunnel opening – but WSDOT has said it’ll be in time for the earliest edge of tomorrow’s morning commute (4 am-ish). We’ll have a separate update when it’s announced, and we also still have one more report in the works from Saturday’s tunnel dedication.

VIDEO: Aerial and underground views from Tunnel to Viaduct 8K

That’s WSDOT drone video of the run/walk that started this day of tunnel/viaduct festivities – with 29,000 participants. We also have three views from inside the tunnel, courtesy of Vy Duong:

Note the signage including the new name of the Mariners’ home (as also seen in above-ground signage we showed in our first report on the dedication ceremony that started just as the run/walk was ending). And here’s Vy’s view as the run/walk reached the tunnel’s south end:

And some of the bicycle officers who were in view at multiple sites throughout the day :

We saw them at the ribboncutting, too, after they escorted runners/walkers out:

Speaking of bicycles – Sunday morning, 12,000 people are registered to ride through the tunnel and on the viaduct, in a sold-out event that is the last component of the celebration weekend before WSDOT goes through final steps to get the tunnel open by early Monday morning.

UPDATE: Highway 99 tunnel dedicated, report #1

FIRST REPORT, 11:12 AM: We are at the south end of the Highway 99 tunnel to cover the 11:30 am dedication/ribboncutting ceremony. Driving on otherwise-closed 99 to access the media-parking zone, we got a look at some of the new signage:

Runners/walkers finishing the 8K are passing by, steps away. Among the West Seattleites waving at us, Deb Greer and Karen Berge of the West Seattle Block Watch Captains Network:

Gathering for the ceremony, many who were involved in making the tunnel happen, from politicians to advisory-group members. West Seattleites we’ve already seen include, in the former category, ex-Mayor Greg Nickels (below with wife Sharon Nickels), and in the latter, longtime advisory/stakeholder group members Vlad Oustimovitch and Pete Spalding.

Also seen already, former Gov. Chris Gregoire, who signed the tunnel bill almost 10 years ago. A West Seattleite who stood by at that Seattle Aquarium ceremony, King County Executive Dow Constantine, is one of today’s scheduled speakers. More former mayors sighted as we got ready to publish this – Mike McGinn, longtime tunnel critic, and Ed Murray, who also was there at the 2009 signing.

Again, though the tunnel is being dedicated today as a prelude to an afternoon/evening of events inside it and up on the soon-to-be-demolished Alaskan Way Viaduct, WSDOT doesn’t plan to open it until early Monday morning.

12:36 PM: Minutes ago, the ribbon was cut:

And a photo:

Full coverage later. First – on to the afternoon of viaduct/tunnel celebrations.
