A new bus system map and service frequency is in the works for the Eastside. An informal poll of fellow bus riders recently seems to indicate that many people don’t know their route will be canceled with the Eastlink Connections plan, even though the changes that will come with the Link’s Crosslake Connection are less than a month away. We also have a major opportunity to spread the word about increases in bus service in other places, and hopefully get new riders since some people will have bus service closer to them or connecting to new destinations.

In Bellevue, the 271 will be “replaced” by the 270 and 220, but the 270 will go north along Bellevue Way to the 520, skipping Clyde Hill (which will then get half-hourly, meandering 249 service to Spring District and South Bellevue P&R instead of a direct connection to UW), and the 220 will cross 405 on Main Street instead of NE 4th, so it will have less coverage along 116th and travel on 112th instead. Newport Way will still be served by the 203 route, and Issaquah will be served by the 218 bus, which will start at the Highlands P&R and end at the Mercer Island Link Station, rather than going all the way to Seattle. There is a segment of W. Lake Sammamish Parkway and NW Sammamish Road where service will not be replaced.
Even if Newport Hill riders are not be using the Link at all, hopefully they’ll have a better experience with the 240 just from the bus service increase to four buses per hour instead of three, as well as service every half hour all night.
There will still be a 249 bus going south of Downtown, but the northern section of its current route along Bellevue Way up to 520 will be served by the 270 instead, and it seems likely that some current 556 riders will switch to that as well.
Changes to 550, 556, and 554 should not happen right away (some are saying October). There is information on the Annual Service Plan page, which says: “Below is an updated summary of ST Express route proposals that would be implemented beginning in fall 2026. Routes highlighted in the chart below have been updated since the last engagement period. [appears that that was November 7, 2025]” More discussion of the shift on the Seattle Transit Blog is here.
Although it may be funny that some changes take place at the end of March and others in the fall, as asdf2 pointed out in this comment thread recently, it makes sense to have some redundancy when there might be unexpected issues with the bridge crossing. It wouldn’t be a surprise if there are outages like yesterday’s as well. The outage did stop the practice runs across the lake, though there’s no indication now of whether the schedule for opening will be affected.
Lots of celebrations are planned for Opening Day on March 28th: BelRed’s celebration will be noon-4pm (art, drumming, pottery painting, etc). Spring District will have a petting zoo, food trucks and vendor booths from 10am-3pm. Bellevue Downtown Station will have live music, food trucks and community booths (time?). South Bellevue’s celebration (10am-2pm) will include live entertainment, food, children’s activities, community booths and a firetruck. Mercer Island’s new station has an opening celebration from 10am-2pm, and there are shuttles starting at 7am from South Bellevue that can get you to the ribbon cutting and street fair at Judkins Park in Seattle, and there will also be celebrations at International District/Chinatown in Seattle. There will be live music at Symphony and a library-hosted stop in Lynnwood. In Redmond, there will be food provided by Microsoft and a cricket demonstration and chai truck at Marymoor. There will be a prize for the first 1000 people who collect stamps at stations along the line. (link)
To see the changes at a glance, it might be easiest to compare the current system map with the map shown above, which you can find here. Changes to the frequency are on the individual PDFs for each route. Some info is adapted from the recent post We have a date!
