A sneak peek at the Crosslake Connection

Yesterday, Seattle Transit Blog writers had the opportunity to join local media outlets to tour the highly anticipated 2 Line cross-lake connection, which is the final piece that will fully unify both the 1 and 2 Lines as it was envisioned in ST2. The connection will fully open to the public this Saturday, March 28th with ribbon-cutting at 9am and revenue service starting around 10am.

The media preview started at South Bellevue Station, which has already been open for Eastside-only revenue service since Spring of 2024. Sound Transit CEO Dow Constantine opened his welcoming remarks with a lofty prediction: Saturday’s opening is expected to be the “biggest” in Sound Transit history. Longtime board member and King County councilmember Claudia Balducci followed up by highlighting East Link’s long history, both as a “political project” in Bellevue as well as its technical challenges.

According to Craig Delalla, director of engineering and operations at Sound Transit, the agency is well prepared for the opening given the many learnings from simulated 2 Line service. Delalla also noted that revenue service will see a mix of 2 and 3-car consists, with 3-car sets more reliably going out during peak periods.

Friday Roundtable: First Transit Trip

When did you start riding public transit independently? Were there certain pivotal trips that made you more of a transit enthusiast and shaped your viewpoint? What’s the youngest people you see now taking transit independently? The full 2 Line opens tomorrow, which many be a similar pivot point for many people. That makes it a good time to reflect on how we all got into transit.

I started riding Metro in 7th grade in 1979 when I chose to go to an alternative junior high school on the other side of Bellevue that didn’t have school buses. At first my parents drove me and I was afraid to take the bus because I’d never been on public transit before. Would I be able to reach the stop cord and activate it, or would the bus sail past my stop? After several months, I took Metro home from school, and saw how easy it was and and other people from my school were taking it. I started taking it to school every day. My first trip to Seattle was to the Record Library (a record-rental shop) at Broadway & Denny. Then I started taking it to the downtown library, and the U-District for its used record shops and bookstores and friends who hung out there.

ST Express 2026 Restructure Approved

The Sound Transit Board just voted to pass the ST Express 2026 restructure, which will be implemented this fall. There are little or no changes from the last proposal. The vote was unanimous.

Until then the ST Express routes will remain unchanged, even though Crosslake Link will open in two days and Federal Way Link opened last December. ST says this is to provide “resiliency” through the World Cup period. I take this to mean if Link breaks down or gets overcrowded during the World Cup, these routes will remain as a backup, and the routes are widely known so residents can help visitors find them and tell them when they run.

There was extensive public testimony at the beginning of the board meeting, though most of it wasn’t about ST Express. The meeting livestream should be on ST’s YouTube channel within a couple days. I listened to bits of the testimony: most of what I heard was advocating for ST3 Link extensions not to be dropped, and there were a few ST Express comments.

We have reservations about parts of the restructure, missed opportunities for further restructuring, and the way public input was handled. The online survey had no text field to suggest changes to other routes or other alternatives for these routes. I sent my feedback in an email to ST, but most people wouldn’t think of that or get around to it or realize other changes were even possible.

More below the fold.

Mercer Island Station

The highly anticipated full East Link extension will open this Saturday, March 28, finally connecting the Eastside to Seattle and the rest of the metro area. Two new stations will open at the same time, Judkins Park and Mercer Island stations.

The Mercer Island light rail station, located in the median of I-90 just north of the city’s Town Center, will help connect Mercer Island residents to Seattle, Bellevue, and the wider metro area.

(Judkins Park I-90 ramp reconfiguration and Access Guide were discussed in previous articles).

Crosslake Connection: 50 Years in the Making

Sound Transit’s 2 Line light rail service will carry it’s first passengers across Lake Washington in just a few days. Puget Sound residents have long envisioned a passenger rail connection between Seattle and the Eastside. In 1968 and 1970, voters failed to approve Forward Thrust rapid transit propositions. Less than a decade later, work began on what would eventually be the Crosslake Connection opening on Saturday.

Essential Groundwork: 1976-1993

In December 1976, a Memorandum Agreement was signed that outlined the construction of an “improved I-90 facility between I-405 and I-5”. The agreement, signed by Seattle, Mercer Island, Bellevue, King County, Metro Transit, and the Washington State Highway Commission, outlined a new I-90 roadway that should include reversible lanes dedicated for buses, carpools, and Mercer Island residents. The document also stated the new “facility shall be designed and constructed so that conversion of all or part of the transit roadway to fixed guideway is possible”. This language was optimistic at the time, but vital a few decades later.

Spring 2026 Service Change

In just 7 days, the Link 2 Line will carry its first passengers across Lake Washington. The long awaited and heavily anticipated opening will cause a cascade of changes across the region’s bus network. Many of these changes will be implemented this Fall, but some will start on March 28. Below is an outline of all Spring 2026 route changes for King County Metro, Sound Transit, Community Transit, Pierce Transit, and Intercity Transit.

King County Metro

Starting March 28, Metro is implementing Phase 4 of the East Link Connections route restructure. The remaining route changes will be implemented in the Fall. The full slate of East Link Connection route revisions was outlined in a previous post. The agency’s South Link Connections route restructure will also be implemented in the Fall. In addition to the changes listed below, several other routes have minor schedule adjustments or bay changes at transit center.

Metro will begin all door boarding on all routes on March 28. Most of the Metro fleet has ORCA readers at each door, so riders are expected to tap in when they board (with an ORCA card or credit card). Passengers paying with cash should still use the front door.

Friday Roundtable: University Link Turns 10

Ten years ago yesterday, March 19, the University Link Extension opened to the public. The extension utilized a new 3.15 mile twin bore tunnel from the north end of the Downtown Seattle Transit Tunnel (DSTT) to the University of Washington, via Capitol Hill. U Link was arguably the first subway-like section on the 1 Line (then Central Link). Trips between the University of Washington (UW) station and Westlake station only took 8 minutes, compared to 20-30 minutes on a bus. The extension caused a significant Metro bus restructure that truncated numerous routes at UW.
