Ridership Patterns for Sound Transit Route 535

Sound Transit Route 535 travels inbound from Lynnwood City Center station to downtown Bellevue, primarily via I-405. This express service stops at Alderwood Mall and in Bothell and Totem Lake.

Route 535 runs every 30 minutes during the week, every hour on Saturdays, and does not run on Sunday. In October 2025, Route 535 had 1,908 average weekday boardings.

Sunday Movies: Beautiful & Useful Transit

Paris’s ultra-useful transit is getting better. (Transit Tangents)

Stockholm’s beautiful metro stations are “the world’s longest art exhibition”. (Not Just Bikes)

We need visionaries like this, and politicians who can prioritize the right things get it done. Paris has automated trains, platform screen doors, service every 5 minutes on many metro and bus lines, station entrances with a pedestrianized street and walk-up retail at both city and suburban stations, no bias against gondolas or funiculars where appropriate, extensive cycletracks, tram tracks in grass beds, etc.

Both Stockholm and Sound Transit spend 1% of their station budget on art, yet Stockholm has much better art. Each station built since the 1970s has a unique look so you can tell at a glance which station you’re at. In Seattle each of the DSTT stations are unique, but the U-Link/Northgate Link underground stations all look alike, so if you can’t see the signs because they aren’t visible from your viewpoint or people’s heads are blocking the view and you missed the audio announcement, it can be hard to figure out whether this is your station or not, so sometimes you just have to go out and hope it is. Whereas if each station were unique, you could tell at a glance at any part of the wall or floor whether this is your station.

The two guys narrating each taking up half the picture reminds a bit me of West End Girls. London in the 80s, with transit.

This is an open thread.

SDOT creating Aurora Ave Community Advisory Group

In 2022, the Seattle Department of Transportation (SDOT) launched a project to redesign Aurora Ave. The highest ridership bus route in Washington, Metro’s RapidRide E Line, carries 13,000 people along the corridor every day. Aurora Ave is consistently one of the most dangerous streets in Seattle. Over the past few years, SDOT has received thousands of responses from the public on how the street should be changed. Based on this feedback, the agency shared a few concepts in 2024. The long-term changes on Aurora will include the following infrastructure and safety improvements:

  • Sidewalks for comfort, safety, and ease of access
  • Better lighting for improved visibility
  • Safer, more accessible street crossings for people walking and rolling
  • Updated drainage to prevent water accumulation 
  • Making it more comfortable and accessible for people walking and rolling
  • Reducing crashes for all road users
  • Improving bus service so it’s more dependable and convenient

How to Finish ST3 Sooner (Without Raising Taxes)

BY ISSAQUAH MAYOR MARK MULLET

The Sound Transit Board is facing large decisions regarding its budget shortfall. The Board is now expected to adopt an updated ST3 plan that will help reshape timelines for light rail segments across the region. Some projects, like the West Seattle line, are proposed to move forward now, while others, including Issaquah’s connection, are pushed back again — this time by six years. Meanwhile, construction of the Seattle Center to Ballard line is postponed indefinitely.

Let’s be honest: that’s frustrating.

Sounder North may end in 2033

A Sounder North train waits at Everett Station (SounderBruce).

Yesterday, the Sound Transit Board Executive Committee reviewed a proposal assembled by the three county executives to realign ST3 for the second time. Although much of the hubbub since has focused on certain decisions presented in that proposal, including plans to temporarily truncate the Ballard Link Extension to Seattle Center and indefinite deferral of the south Seattle infill stations, an understated assumption of the plan includes discontinuation of the Sounder N Line beginning in 2033.

Sound Transit Updates ST3 Plan Amid Financial Constraints

On Thursday, Sound Transit Board Chair Dave Somers will share a resolution to update the Sound Transit 3 system plan. This update will help align the agency’s future Link extensions with the available funding. Due to record-breaking inflation and more accurate price estimates, Sound Transit is facing a $34.5 billion funding shortfall. In March, the agency shared three potential approaches it was considering for re-aligning ST3. These suggestions alarmed Sound Transit tax payers and transit advocates. Over the past few weeks, groups supporting different projects have sprung up, demanding that Sound Transit build the voter-approved system.

The resolution designates some projects to be fully funded through completion, some to be partially funded through planning or design, and others to be deferred until additional funding becomes available.

ProjectFunded by Resolution R2026-11
Ballard Link Extension– Construct CID to Seattle Center
– Design Seattle Center to Ballard
West Seattle Link Extension– Construct to Alaska Junction, skipping Avalon station
Everett Link Extension– Construct to Everett
Tacoma Dome Link Extension– Construct to Tacoma Dome
Graham St and Boeing Access infill stations– Design both stations
T Line Extension– Construct to Tacoma Community College, opening pushed back from 2035 to 2043
Kirkland-Issaquah Link– Construct full line, opening pushed back from 2041 to 2050.
DuPont Sounder Extension– Planning phase
Maintenance Facilities (Link North, Link South, Sounder, ST Express)– Construct Link and Sounder maintenance facilitates
– Partially fund ST Express bus base

West Seattle / Downtown via SODO busway

Sound Transit still plans on building a new Link line to West Seattle. As Sound Transit struggles to find ways to fulfill the ST3 promises, there is a better option for West Seattle transit riders. With a relatively small investment in bus-based infrastructure, we could give riders in West Seattle the best of both worlds: a fast connection to Link and a fast, direct trip to downtown.

Connect the SODO Busway with the Spokane Street Viaduct

In 2012 SDOT evaluated various ways to connect West Seattle with downtown Seattle by bus. Since then they’ve added an eastbound ramp from the Spokane Street Viaduct to 4th Avenue South. This ramp could be leveraged to quickly connect to the SODO Busway. If this approach has significant delays, it would be relatively easy to build a second ramp just to the east of that one, directly connecting to the SODO Busway. The Spokane Street Viaduct already has a dedicated bus lane extending partially east of Highway 99. It would be trivial to extend the bus lane to the ramp at 4th or the new one. Buses would then travel in their own lane from West Seattle to downtown. Going the other direction, a new ramp could be built from the southbound busway to westbound viaduct. This would be similar to the one at First Avenue and relatively inexpensive. This work could be done much faster than a Link extension and the savings could be put immediately into running buses a lot more frequently to and within West Seattle.

Only Holgate and Lander Street cross the SODO Busway. ST3 proposed building overpasses to improve Link. The same would apply to the busway. The Holgate to Beacon Hill viaduct could be extended to cross the Link tracks and the busway. A similar link could be built for Lander between 4th and 6th Ave. This would also improve the reliability of Link and the other buses that use the busway. The toughest section for buses is probably between Stadium Station and CID. The report also considered various ways to improve that.

One advantage of this proposal is that the improvements could be iterative. The buses could run more often almost immediately. Southbound buses could use Lander Street and the First Ave ramp until the southbound busway-to-viaduct ramp is complete. Northbound buses could use the ramp to 4th Avenue South. Each improvement could happen bit by bit.
