Work prepares system for smooth transition to 33 miles of new light rail extensions

Publish Date

Getting ready for the 33 miles of Link extensions coming over the next three years involves a lot more than just construction on the extensions.

It also means making sure that our existing operations are in top condition as we prepare to tie the new extensions into our current one.

This work is getting us ready for the future, which is why we’re calling it Future Ready.

Starting in July through early 2023, we’re going to have a series of construction and maintenance activities that will help us prepare for the transformative changes ahead.

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

The first work to get underway will involve platform work at Columbia City Station.

Beginning July 11, one side of the tracks through Seattle's Rainier Valley will close for two weeks to enable platform work at Columbia City Station.

The first two-week period of construction at Columbia City will run July 11-24. Another passenger-focused improvement is to delay the second two-week period of construction at the station to Aug. 19-Sept. 1, avoiding two high-ridership sports events.

The work involves removing cracked and failing platform tiles and rebuilding a concrete base to ensure new tiles offer good durability, eliminating tripping hazards and safety risks from cracking tiles.

The bulk of the work is at the edge of the platform. For the safety of the workers, the tracks nearest that section of the platform have to be closed.

To help alleviate crowding, all trips will operate with four-car trains. 

The next project will take place over two three-day periods in October and November in the Downtown Seattle Transit Tunnel (DSTT), as we work on the overhead catenary system. As a result of this work, for many projects the entire tunnel will not need to be closed for future work in a single section, as is currently the case.

Here are dates and details for the first two phases of the Future Ready projects, as well as what to expect with later work.

We will post updates and rider alerts that include specific dates and durations for those projects as details are finalized.

Time period Travel Impact

Monday, July 11 to Sunday, July 24

1 Line train frequencies will be reduced to 20 minutes between Angle Lake and Stadium stations. The work requires the closure of one track at Columbia City Station, forcing all trains to use a single track between Mount Baker and Othello stations. 

Trains will run approximately every 10 minutes between Northgate and Stadium stations. Every other train heading south from Northgate will turn back at Stadium Station. The trains exterior signs will say if they are headed to SeaTac/Angle Lake or Stadium.

Friday, Oct. 21 to Sunday, Oct. 23

Friday, Nov. 11 to Sunday, Nov. 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 in each direction until 11 p.m. From 11 p.m. until end of revenue service, a Link bus shuttle will be available to connect passengers between Capitol Hill Station and SODO Station.

A period of five days in late Q3 2022

In order to repair and replace the overhead catenary system, Link will be shut down between Rainier Beach and Tukwila International Blvd. stations with a Link bus shuttle connecting passengers between these two stations.

A period of at least three weeks in Q4 2022

Trains will be single tracked through the DSTT and train frequencies will be reduced to 20 minutes.
Q1 2023 This work is needed to complete connections between the current 1-Line service and new 2-Line tracks that will link riders to the Eastside. Impacts are still to be determined.

To get the latest information about these service disruptions, make sure you sign up for Rider Alerts.

Doing this work now means we will impact far fewer riders now than if we delayed them until after further expansions open.

While the disruptions that this work will cause are unavoidable, we will work hard to minimize the impact on service to our riders. The end result will be a safe and improved system ready for our next phase of growth.
