Light Rail Riders Will Have to Switch Trains to Get Through Downtown Tunnel During East Link Construction

Sound Transit light rail riders traveling through the downtown Seattle transit tunnel will have to switch trains on a new, temporary center platform at the Pioneer Square station for ten weeks in early 2020 to accommodate construction to move tracks and install switches for the new East Link train line, which opens in 2023, into the existing rail system. During those ten weeks, people traveling through the tunnel in either direction will stop at Pioneer Square, deboard on a 14-foot-wide platform in the middle of the tunnel, and switch to the train that has just arrived from the opposite direction. After two minutes—an amount of time Sound Transit planners say is necessary to allow passengers on each train to get across the platform and reboard, and for train drivers to get from one end of the train to the other—the trains will continue in the same direction from which they came.

Sound Transit staffers said train doors will not open until another train has arrived from the opposite direction, to prevent riders from succumbing to the “temptation” to rush across the open trackway to the opposite station platform. The temporary center platform will be staffed with security and Sound Transit wayfinding staff during all hours when trains are running.

“This is a necessary inconvenience so we can enjoy the massive convenience of having access to 10 stations on the Eastside in 2023.” – Sound Transit CEO Peter Rogoff

If you have trouble visualizing how this would work, Sound Transit has created a couple of animations that I found extremely helpful. Essentially, trains that go to the University District station will be traveling to Pioneer Square and turning back, and trains coming from Angle Lake and the airport will be doing the same thing from the south. Four stations will operate with only one platform at a time during construction—Stadium, Chinatown/ID, University, and Westlake.

Additionally, the tunnel will be shut down altogether for three weekends during the construction period; during that time, riders will have to transfer to street-level buses between the Westlake and SoDo stations.

While construction is going on, four-car trains will operate at 12-minute frequencies all day (currently, Sound Transit runs three-car trains more frequently during rush hour and less often when demand is lower.) The result will be more crowding during busy periods—trains will have about 23 percent less capacity during the weekday peak—and less crowding during off hours, when there will be 11 percent more room for riders to spread out. Sound Transit staffers say they’re working on a plan to accommodate bikes and luggage when trains are more crowded than usual.

At a meeting of Sound Transit’s newly christened Rider Experience and Operations Committee meeting Thursday, Sound Transit CEO Peter Rogoff called the 10-week partial closure “a necessary inconvenience so we can enjoy the massive convenience of having access to 10 stations on the Eastside in 2023,” and predicted that riders would “scarcely remember the inconvenience of the 10 weeks in 2020, given the benefits that the whole region will get when East Link is done.”

Buses May Leave Downtown Tunnel for Surface Streets As Soon as March 2019

Dozens of buses per hour may move from downtown transit tunnel and onto surface streets as soon as next March, thanks to an amendment  adopted by the city council’s transportation committee on Tuesday. The amendment, proposed by council member Rob Johnson, alters legislation vacating several public alleys for the expansion of the Washington State Convention Center,  which will require buses to move from the tunnel onto surface streets sometime next year. Johnson’s amendment, which passed 4-3, struck language that would have barred the convention center  from kicking buses out of the tunnel until September 2019, which bill sponsor Mike O’Brien said was intended to give the city and King County Metro more time to implement transit improvements downtown. The amended legislation would allow the developers to evict buses from the tunnel as early as March 2019,  adding 40 more buses  to downtown streets in each direction during rush hour. (March and September were the two possibilities because those are the months when Metro implements its service updates.)

Although a group of Seattle Department of Transportation and council staffers warned committee members that the city and  county might not be able to implement all the improvements they need to make by March, Johnson countered that it was time to “hold SDOT’s feet to the fire on getting some of these transit pathways up and running in a more aggressive timeline.” If the council gives SDOT an additional six months, he added, they are likely to take it. Johnson also echoed comments made earlier by convention center developer Matt Griffin about the need to avoid unnecessary delays that could increase the cost of the project and forestall job creation and affordable housing construction.

On Tuesday, O’Brien argued that adding so many buses to surface streets in March will result in unnecessary traffic chaos at a time—known as the “period of maximum constraint”—when downtown streets will be most impacted by various downtown construction projects, including the demolition of the Alaskan Way Viaduct and the opening of the new  tunnel on the downtown waterfront. March 2019, he added, may be an unrealistic deadline for the city and county to coordinate and complete all the improvements planned as part of the delayed One Center City project, including the implementation of off-board payment for all buses that travel on Third Avenue and the reconfiguration of Fifth and Sixth Avenues for buses, which will require new bus lanes and tricky signal timing changes.

“Next March, I think we’re all going to wish we had six more months of buses operating in the tunnel,” O’Brien said. “Even with buses operating in the tunnel, we’re going to have some major chaos on the streets downtown. … We’ll survive. The city won’t end. But I think it’s going to be a real mess.”

Contacted after the vote, Johnson said he isn’t convinced that the “period of maximum constraint” will be as cataclysmic as some of his colleagues, and SDOT, seem to think. As evidence, he points to the Alaskan Way Viaduct, which carried 120,000 cars a day as recently as 2009, when the city, county, and state signed an agreement to build a four-lane bypass tunnel and a wide surface Alaskan Way to replace the aging bridge that spans the downtown waterfront. At the time, advocates for building a bigger tunnel or rebuilding the viaduct said the number of cars driving through downtown would only grow. Instead, the number has steadily shrunk—to just over 90,000 in 2016, according to Johnson.

“I’m cognizant of the doomsday period of maximum constraint that everyone’s talking about, but also, I look at downtown, with its 24-plus lanes going north-south, and I think, that’s plenty of capacity, if we could just do a better job at managing that capacity,” Johnson said. “I get frustrated by the delay of projects that could have real benefits for transit pathways. I  really want to light a fire under SDOT to make some of these projects happen and not just take as long as we give them to do it.”

O’Brien says it’s unfair to lay every delay at SDOT’s feet; in the case of implementing off-board payment for buses on Third Avenue, for example, King County Metro is equally responsible.  “The frustrating thing for me is that Rob is just saying, ‘We think SDOT needs to work harder,’ and I’m like, Our experts just showed up and said we can’t do it in six months. And Rob is just saying, ‘You better.’

“This is all in the context of the new tunnel and tolling and rebuilding Alaskan Way. It’s not like SDOT just has nothing going on,” O’Brien says.

On Tuesday, the developer, Griffin, suggested that if the city allows buses to stay in the tunnel until September, it will result in costly delays, the elimination of tens of thousands of “bed hours” in affordable housing his firm has agreed to build as part of its deal with the city, and could potentially scuttle the project. O’Brien says that when Griffin made that last claim, he thought, “we’re outside [the realm of] rational thought—now you’re just making threats.”  He added: “Matt’s a powerful guy who has some influence about other things that other people care about.”

Griffin gave the maximum contribution, $700, to Johnson’s 2015 campaign, and contributed $10,000 that year to the Seattle Metropolitan Chamber’s Civic Alliance for a Sound Economy PAC, which was the largest contributor (at $46,500) to an independent expenditure campaign supporting Johnson. Griffin did not contribute to O’Brien’s campaign.

There’s still another situation, by the way, in which the convention center could be forced to let buses stay in the tunnel until September of next year: The legislation the committee adopted requires the convention center developer to obtain all its construction permits by July 1 of this year; if that doesn’t happen, buses must stay in the tunnel until September 2019.

The full council is scheduled to vote on the convention center street vacation agreement today at 2:00.
