Overview & Background

East Link is a voter-approved project to expand light rail from downtown Seattle to the Eastside with stations serving Mercer Island, south Bellevue, downtown Bellevue, Bel-Red, and Redmond's Overlake area. East Link will connect to the Central Link light rail system already operating between downtown Seattle and Sea-Tac Airport.  Central Link opened an extension to the University of Washington in early 2016, and a further extension to Northgate opens in 2021.

East Link has completed the final design phase (trackway, stations, art installations and construction methods, including sequencing and mitigation) and has now begun initial construction in Bellevue. By mid-2017, construction activities will begin on Mercer Island too.

Sound Transit convened an Independent Review Team (IRT) to assess 23 identified safety issues related to operating light rail across the floating bridge, and sought concurrence from WSDOT and FHWA.  A user-friendly citizens' guide to these resolved technical considerations will be available in the spring of 2017 from Sound Transit.

Once all construction components are complete, Sound Transit will test and open the entire East Link corridor for passenger service in 2023. Sound Transit is also conducting environmental review on a future extension to downtown Redmond.

The Eastside is one of the region's fastest growing economic and residential centers. The job and population growth, however, is putting increasing demand on the Eastside's transportation system. East Link will provide an alternative to driving on congested roads. Because light rail trains operate in their own right-of-way, they provide fast, smooth and reliable service no matter what the weather or traffic conditions. East Link will connect directly to the Central Link light rail line for a no-transfer ride between Redmond, Bellevue, Mercer Island and the University of Washington via downtown Seattle and Capitol Hill. A ride from Mercer Island to the UW campus will take just 20 minutes.

What's Happening Now

On February 13, 2017, the City Council voted to take legal action that would seek to temporarily halt the closure of the I-90 center roadway to provide the City, the Washington State Department of Transportation (WSDOT) and Sound Transit the ability to continue their ongoing negotiations about preserving mobility and safety for Mercer Island residents. Read the full press release.

Litigation and negotiations continue -- check City homepage news column for latest updates.
 

Get Involved

A series of public input opportunities occurred in September and October 2015; click here for presentation materials and summary comments from Sound Transit's Mercer Island webpage.

The City held a community open house in November 2016 to update the public on ongoing negotiations with Sound Transit, WSDOT, and the Federal Highway Administration (FHWA), and to solicit input on future vehicle access to I-90 during light rail construction.  Additional community listening sessions about rail issues have occurred throughout spring 2017 with various stakeholder groups. Learn more about community meetings here. Sound Transit plans to hold its customary pre-construction outreach open house meeting in June 2017.


 


Project Schedule

The East Link light rail will run across the center roadway bridge between Seattle and Mercer Island, and will displace permanently all vehicle traffic onto the mainline roadways. Before that transition, WSDOT will install carpool/HOV lanes in each direction on the current mainline roadway of I-90, under a project known as R8A-Stage 3

At this point, WSDOT intends to close the existing center roadway June 3, 2017 to allow Sound Transit to begin light rail construction. East Link Light Rail is scheduled to open for service in 2023.

The Environmental Process

In fall 2006, Sound Transit, the Federal Transit Administration and the Washington State Department of Transportation began the environmental review process for East Link with a public scoping comment period including four public meetings held at various locations in the project's vicinity. During scoping, Sound Transit received about 300 written and oral comments on the proposed project. These comments were included in the Scoping Summary Report, which was presented to the Sound Transit Board and made available to the public in November 2006.

From 2006-2011, Sound Transit evaluated 24 route alternatives for East Link; it received more than 1,800 comments during the five year process and held 28 open houses, hearings and workshops to gather community input.
 
Environmental review and preliminary engineering for East Link Extension was completed in 2011. Sound Transit issued a Final Environmental Impact Statement (FEIS) and the Sound Transit Board selected the project to be built in July 2011. The Federally issued Record Of Decisions (ROD) finalized the alignment that the Sound Transit Board selected through this work, completing the required process under the National Environmental Policy Act.

On April 5, 2017, Sound Transit and WSDOT issued an Addendum that updates the Final Environmental Impact Statement (EIS) issued in July 2011 --and subsequent 2013 and 2016 addenda-- by providing additional analysis and information about the project. It describes changes in operation of I-90 high-occupancy vehicle (HOV) lanes and project refinements associated with transit integration on Mercer Island, evaluates the potential impacts of these changes, and identifies changes to mitigation measures.

What is Light Rail?

Light rail is versatile and flexible enough to run at street level, through tunnels, or in elevated right-of-way, depending on individual routes. It also can expand and grow with increasing demand. Light rail trains are powered by an overhead electrical power source. Sound Transit's Link light rail vehicles offer level boarding (no steps required) that can operate singly or combined into two-, three- and four-car trains that can carry up to 800-1,000 passengers, sitting and standing.
 

Sound Transit's Transportation Network

Link light rail is a key element of the Puget Sound region's long-term transportation network, which also includes ST Express regional buses, Sounder commuter trains, local buses, ferries and roads.
 

Benefits of Link Light Rail

According to Sound Transit, here are some of the top expected benefits:
  • Fast, frequent and reliable service 20 hours a day
  • Exclusive and semi-exclusive right-of-way for rail transit, separated from other traffic and congestion
  • East Link will connect to the Central Link line providing a one-seat ride (no transfers) from Overlake to the University of Washington via Bellevue, Mercer Island, downtown Seattle and Capitol Hill
  • Reliable connection to Sea-Tac Airport
  • Light rail trains are electric and do not emit harmful contaminants into the air
  • Development concentrated around light rail stations promotes walkable communities, which leads to improved public health and mobility
  • Light rail can carry crowds associated with fairs, sporting events, concerts, festivals, and other special events; trains can be lengthened based on demand.
