Sound Transit maintenance projects to affect light rail service

Runners can expect delays later this year

Light rail riders can expect periods of less frequent service and replacement bus service for the rest of the year and into next year as Sound Transit conducts several maintenance projects.

“Preparing for the 33 miles of link extensions that will be done over the next three years involves much more than just building the extensions,” according to Sound Transit. “It also means making sure our existing operations are in top condition as we prepare to tie the new extensions into our existing ones. This work is preparing us for the future, which is why we call it Future Ready.”

Starting in July and running through early 2023, the agency will have a series of construction and maintenance activities that will help it prepare for the transformative changes ahead.

But these Future Ready activities mean passengers will need to prepare for intermittent periods of less frequent service and replacement bus service.

The first work to begin will be the replacement of the station platform tiles at Columbia City Station in Seattle.

Because the tiles are failing well short of their expected lifespan, creating hazards, one-time monitoring is necessary while the tiles are being replaced and the deck is being repaired.

The next project will take place over two three-day periods in October and November in the downtown Seattle transit tunnel as Sound Transit works on the overhead catenary system. As a result of this work, for many projects it will not be necessary to close the entire tunnel for future works in one section, as is currently the case.

Sound Transit staff report that doing this work now means the agency will affect far fewer riders now than if it delayed the work until new extensions open.

“While the disruptions this work will cause are unavoidable, we will work hard to minimize the impact on service to our customers,” according to Sound Transit. “The end result will be a secure and improved system ready for our next phase of growth.”

Travel impacts

• July 11-24; Aug. 22-Sept. 4

Line 1 train frequencies will be reduced to 20 minutes systemwide in each direction during all hours of operation while crews replace platform tiles at Columbia City Station. The work requires the closure of one track at the station, forcing all trains to use a single track between Mount Baker and Othello stations.

• Oct. 21-23; Nov. 11-13

As a result of work on the overhead catenary system in the Downtown Seattle Transit Tunnel (DSTT), train frequencies will be reduced to 20 minutes each way until 11 p.m. A Link shuttle bus will be available from 11pm until the end of service. to connect passengers between Capitol Hill Station and SODO Station.

• A five-day period at the end of quarter 3 of 2022

To repair and replace the overhead catenary system, the link will be closed between Rainier Beach and Tukwila International Blvd. stations with a Link shuttle bus connecting passengers between these two stations.

• A period of at least three weeks in Q4 2022

Trains will be single-track through the Seattle Downtown Transit Tunnel and train frequencies will be reduced to 20 minutes.

• Quarter 1 2023

This work is required to complete the connections between the current 1-line service and the new 2-line tracks that will link the corridors to the east side. The impacts are yet to be determined.
