Systems and testing: construction of the systems (guide wires, electronics, signaling, etc.) will occur as each segment is completed and will be completed mid-2021. Testing of the entire East Link will take approximately one-year, with revenue service expected to begin late 2022 or early 2023.

Operations & Maintenance Facility

In addition to the stations, Sound Transit is constructing an Operations and Maintenance Facility (OMF East) in the BelRed area (Bellevue) where light rail vehicle (LRV) storage and maintenance will be located. This "OMF-East" is needed to house the expanded fleet of LRVs with the East Link extension. Design of the facility will complement the BelRed Corridor Plan vision to transform the 900-acre corridor to capitalize on light rail investment and provide transit-oriented development opportunities.

Collaborative Design Process

At the time East Link (Sound Transit 2) was approved in 2008, the City of Bellevue and Sound Transit began to work closely, through a collaborative design process to create a Regional Light Rail Transit that meets regional and city needs. A Memorandum of Understanding (MOU) adopted in 2011 between the city and Sound Transit addressed the construction, operation, and maintenance of the light rail project was amended in 2015 to address coordination of City capital projects and terms regarding the OMSF.

Members of the Light Rail Permitting Citizen Advisory Committee (CAC) were appointed by the City Council to help ensure community issues and concerns were to be addressed during the permit review process as defined in Bellevue’s Land Use Code. A great deal of public input was received at meetings and public events that helped shape the Design and Mitigation (D&M) Permits to be issued by the City.


The collaboration between Sound Transit and Bellevue continues as the design phase of the project comes to close and the construction phase begins in early 2016. Sound Transit and staff from the City’s permitting departments are working together to help minimize construction impacts to neighborhoods, businesses, traffic and the environment. The 2015 MOU requires various mitigation for the East Link project and is captured in Exhibit OMore about East Link mitigation.
