Alaskan Way viaduct

Pike Place Market

A major addition is coming to the Pike Place Market. The $65 million dollar project includes a pedestrian connection to the waterfront. Monday, the Seattle City Council approved selling $34 million in bonds to help pay for it.

Five workers installing rebar on a concrete wall at north portal of the Alaskan Way Viaduct Replacement Project fell about 25 feet when a wall of rebar gave way.

Seattle Fire spokesman Kyle Moore says two Seattle firefighters walked about a half mile into the tunnel and carried out one of the injured men while the four others walked out after the Thursday afternoon incident.

One of the men who walked out was not injured, while four others were taken to Harborview Medical Center, he said. One of the men suffered a fractured arm and was in stable condition, while the three others were evaluated.

Settling ground is affecting the Alaskan Way viaduct, Pioneer Square buildings and underground water pipes, Seattle utilities officials said Monday. Engineers think the sinking is connected to the Highway 99 tunnel project, but it probably has little to do with actual digging.

The safety of the Alaskan Way viaduct will be back on the table Monday when the Seattle City Council will hear from the Washington State Department of Transportation about planning for a short- or long-term closure of the busy highway that runs along Seattle's waterfront.

Officials overseeing the replacement of Seattle’s Alaskan Way viaduct are trying to tamp down safety concerns. But under questioning Monday from Seattle City Council members, they had a hard time coming up with an answer for when people should start to worry.

The plan to dig a shaft 12 stories deep to fix Bertha, the Seattle tunnel boring machine, has been put on hold while archaeologists make sure crews won’t dig through important historical sites. 

On Thursday, workers started boring approximately 60 holes, each about as wide as a grapefruit, and digging as deep as 40 feet down through layers of Seattle's floor, which, at the moment, is also Bertha's ceiling.

State highway engineers will shut down a stretch of the Alaskan Way viaduct later this month to take a closer look at cracks found on the roadway.

What workers found during a routine inspection of the viaduct on March 1 isn’t that unusual, says Tom Baker, an engineer with the Washington state Department of Transportation.

The Washington state Transportation Department says that, as expected, the contractors digging a highway tunnel under downtown Seattle will repair a seal system on the tunneling machine by digging a shaft in front of it.

The prospect of taking the State Route 99 tunneling machine known as Bertha offline for as much as half a year is not good news for the company operating it. But one Seattle tunneling expert says it could be worse.

“It’s really a problem with the machine itself. I think it’s something that can be repaired,” said the University of Washington’s Joseph Wartman. “And I think in a couple of years when the tunnel is open, people will have forgotten about this.”

Seattle Tunnel Partners

Washington transportation officials and the private contractor operating the tunneling machine known as Bertha disagree on what’s holding up progress on the Highway 99 tunnel project. Neither had definitive answers, but appearing together Tuesday at a news conference, it became clear they’re leaning toward conflicting theories.

The state contractor hasn’t yet decided how to fix the broken seal near Bertha’s bearing, but “either way, this process will take months,” said the state Department of Transportation late Monday.

Remember that big steel pipe — eight inches wide, part of an old well?

The Washington State Department of Transportation never actually accused that pipe of blocking Bertha, but it was definitely a prime suspect.

But on Friday, WSDOT said the pipe isn’t, and never was, the problem.

Seattle's massive tunneling operation is on hold yet again due to ongoing problems with the world's largest boring machine.

After a seven-week stoppage, crews restarted the tunneling machine earlier this week and moved it forward about two feet. Washington state's Department of Transportation said Friday that the machinery showed above-normal temperature readings when that movement occurred.

A Washington Transportation Department spokeswoman says the giant machine digging a highway tunnel under downtown Seattle has advanced two more feet, far enough to allow crews to build the next concrete ring of the tunnel.

Tuesday's progress was the first for the machine in nearly two months, since it stalled Dec. 6 some 60 feet underground.

Senator: Seattle Should Pay For Tunnel Cost Overruns

A leading Republican in the state Senate says Seattle taxpayers should foot the bill for any potential cost overruns on the Alaskan Way Viaduct replacement project.

The machine digging a tunnel to replace the elevated highway along Seattle's waterfront has been stuck for more than a month, raising concerns that more funds will be needed for that $1.4 billion project.

What if Seattle gets stuck with cost overruns on the Alaskan Way Viaduct replacement project?

That question sparked a lively exchange on KING-TV between the two candidates for mayor of Seattle during their first televised debate.

During the hour long debate sponsored by KING-TV, KIRO-FM and The Seattle Times, Mayor Mike McGinn and Sen. Ed Murray traded jabs on everything from leadership style to police reform.

But their discussion of the tunnel project raised one of the most interesting questions.

The drill known as Bertha is back to eating dirt after a slow start, then a delay, then a delay caused by the delay.

The massive machine boring the Highway 99 tunnel beneath Seattle had been sitting still while two labor unions duked it out over a handful of jobs.

Gov. Jay Inslee announced last week he’d brokered a deal in the dispute, and said the digging would resume after a few days.

The State Route 99 tunnel boring machine, better known by her nickname “Bertha,” is poised and ready to begin the dig under downtown.

Replacing Seattle’s Alaskan Way Viaduct is going to bring more than dust and noise; it’s also predicted to create a mass exodus of rats and cockroaches in search of quieter places to hide, feed and cause damage.

The complete removal of Seattle’s Alaskan Way Viaduct is years away. The tunnel replacing it won’t open till 2015.

But this summer marks a crucial moment for the iconic Pike Place Market as the waterfront is redeveloped.

The long goodbye to Seattle’s Alaskan Way Viaduct has begun.

With some ceremonial scoops of dirt, officials today began digging a pit for the giant machine that will chew up the earth under Seattle like a massive termite creating the deep-bore tunnel.

Should the Pike Place Market be connected to Elliot Bay with new walkways?

That’s one of many expensive questions on the minds of landscape designers in charge of rebuilding Seattle’s waterfront.

In less than a week, the city will once again convene stakeholders and the public for help shaping the future of the city’s  “front door” on Puget Sound.

The group Waterfront Seattle is calling on the public to join in discussions that will help determine what the new waterfront will look like, after the Alaskan Way Viaduct comes down.

It’s been a long running problem – how to keep and create affordable spaces for artists to live, work and perform in.

That’s the focus of Cultural Space Seattle, a two-day event beginning Tuesday at Town Hall. The City of Seattle is asking a wide range of people to roll up their sleeves to look for ways to preserve Seattle’s vibrant arts scene.

Watch as an entire section collapses:

The Washington Transportation Department says Seattle's Alaskan Way Viaduct will reopen at mid-day Saturday, ending traffic congestion drivers call "viadoom" a day-and-a-half early.

The Washington Transportation Department says the work that has shut down the Alaskan Way Viaduct in Seattle is on schedule.

WSDOT has published a new round of photos on it's Flickr site.

Spokesman Travis Phelps says the viaduct is scheduled to reopen early Monday. He said Wednesday it's unlikely the work would wrap up ahead of schedule. Some had hoped it would reopen in time for Sunday's Seahawks game in CenturyLink Field.

So far – not so bad. That seems to be the upshot of the first weekday commute without the Alaskan Way Viaduct through Seattle. Traffic was slow, but not totally gridlocked Monday morning.

The state Department of Transportation says many people heeded their warnings and changed their commute patterns. That was certainly the case on board the West Seattle water taxi, which picked up nearly twice as many riders.

The Monday morning commute in Seattle was congested but moving slowly as drivers dealt with "Viadoom," the closure of the Alaskan Way Viaduct, one of the city's main north-south highways.

The Rat City Rollergirls and a motorcycle stunt team will be taking over the Alaskan Way Viaduct for half an hour Saturday before demolition begins on the Seattle elevated highway.

The so-called "Carmageddon" in Los Angeles this summer was a bust — but its Seattle-based sequel "Viadoom" is being billed as the real deal.

When the Alaskan Way Viaduct shuts down at 7:30 p.m. this Friday, nearly 90,000 drivers will face detours and delays. Transportation officials have been encouraging commuters to ditch their cars during the nine day closure. Otherwise, they say roads through the city will be total gridlock.

For anyone who thought they were anonymous driving the city streets of Seattle, the truth is you’re being watched.

And while this might normally be upsetting, the all-seeing cameras positioned over freeways, bridges and intersections may soon be a lifeline during the impending nine-day closure of the Alaskan Way Viaduct.
