South Bellevue Station FAQs

What hours is construction noise allowed? Are expanded hours allowed?

Bellevue’s Noise Control Code (Noise Code) regulates and establishes permissible noise levels based on the type of land use (e.g. residential, business or commercial). The code also sets daytime noise levels in residential areas at a maximum of 55 dBA (decibel level) and nighttime (between 10 p.m. and 7 a.m.) at a maximum of 45 decibels. 

Construction noise is allowed between 7 a.m. and 6 p.m., Monday through Friday and 9 a.m. to 6 p.m. on Saturday. Construction noise is prohibited beyond these hours, on Sunday, and on certain holidays, unless otherwise allowed by a city-approved permit. The Noise Code does contain exemption provisions.

For the East Link light rail project, the city has approved the following Expanded Exempt Work Hours Permits for the South Bellevue segment (Permit 15-124380 LY)    

  • East Channel Bridge to the south end of the South Bellevue light station. Work is anticipated to occur in 10 to 12-hour shifts (during 24-hour period) for a 39 months. Maximum noise level is 77 dBA
  • North of the South Bellevue station to the “Wye” at 112th Avenue SE. Work is anticipated to occur from 7 a.m. to 10 p.m. on weekdays and from 7 a.m. to 9 p.m. on weekends for 34 months. Maximum noise level is 80 dBA.
  •  Note: A supplemental permit (17-114040 LY) was issued to allow for the installation of pre-cast tub girders for the light rail guideway to occur within the South Bellevue Station site. This permit covers the anticipated operations from January 2018 through January 2019.

How do I report noise complaints from light rail construction?

City code does not regulate construction noise  Monday through Friday, 7 a.m. to 6 p.m. and Saturday, 9 a.m. to 6 p.m.

City code does allow work hours for certain activities to be extended. In the case of light rail construction, the city has approved expanded work hours for certain activities in the South Bellevue, Central Bellevue, and BelRed segments as well as for the tunnel.

South Bellevue Extended Work Hours Permit
See map depicting Zone A and Zone B. Sound Transit activated the permit in June 2017.

  • Zone A: East Channel Bridge to south end of South Bellevue Station. 10-12 hour shifts during 24-hour period for 39 months.
  • Zone B: North of South Bellevue Station to "wye" at 112th Ave SE
    • Weekdays: Work allowed 7 am to 10 pm
    • Weekends: Work allowed 7 am to 9 pm for 34 months.
  • The City approved an Extended Work Hours Permit for the South Bellevue segment so that Sound Transit's contractor can conduct work around the clock for 39 months. This permit covers only work that crosses the I-90 ramps south of the South Bellevue light rail station. This work includes construction over an active freeway which cannot be accomplished during the daytime (and requires closure of the ramps). This is not continual 24-hour work across 39 months but will involve intermittent closures, with specific dates to be controlled by WSDOT.

    The South Bellevue Extended Work Hours permit (16-124380 LY) also allows work to be conducted up to 10 p.m. on weekdays and up to 9 p.m. on weekends north of the light rail station site (under construction) to the Wye on 112th Avenue SE for up to 34 months. This is to allow construction on Bellevue Way to be completed in a more expeditious manner.

    There is an additional extended work hours permit issued in order for the delivery and installation of large concrete girders at the South Bellevue station. Transportation of these is not allowed by WSDOT during daytime hours. This permit is not for continual 24-hour work throughout the duration of the permit but for intermittent work.


What construction is happening adjacent to Bellevue Way SE?

Expect construction activities adjacent to Bellevue Way Southeast, from I-90 to 112th Avenue SE, in three phases:

Phase 1

The first phase of construction involved the relocation of public and private utilities on Bellevue Way SE. From June through November 2017, full and partial weekend closures of Bellevue Way and the I-90 ramps were necessary to complete the work. (Phase 1 is complete.)


Phase 2
Once utility work was complete, construction of the guideway (e.g. columns) and trench began in earnest. Construction of the South Bellevue Park-and-Ride garage continues.  (Phase 2 is underway spring 2018.)


In April 2018, a new traffic control plan was implemented on Bellevue Way SE to allow for this construction. (While this construction occurs, additional construction will be happening on 112th Ave. SE. See the FAQs about 112th Ave. SE.)

Will there be road and lane closures on Bellevue Way SE?

Yes. There will be full and partial weekend road closures as well as lane closures throughout construction of the South Bellevue Segment.

During the initial phase of construction for utility work, full weekend closures were implemented and extended from I-90 to the “Y” at 112th Avenue SE. These closures occurred between June and November 2017.

Starting in April 2018, traffic control planned for Bellevue Way SE includes:

  • Two lanes open northbound and one lane open southbound in the morning
  • Two lanes open southbound and one lane open northbound in the evening
  • All lanes open 6 p.m. to 6 a.m. on weekdays; all lanes open all day on weekends
  • Occasionally, only one lane will be open in each direction between 10 a.m. and 2 p.m.
  • Occasionally, work may continue until 8 p.m. for certain activities. This will be more common in the summer months.
  • No lane closures are expected between the Thanksgiving 2018 and New Year’s Day 2019 holidays.

Will closures of Bellevue Way be coordinated with any closures of I-90?

Yes. Both the Washington State Department of Transportation (WSDOT) and the Bellevue Transportation Department have reviewed the anticipated closures. Sound Transit and the Contractor will coordinate closely with WSDOT and the City prior to traffic changes that affect I-90 motorists.

What construction activities are occurring adjacent to 112th Avenue SE?

Construction activities adjacent to 112th Avenue SE includes, among other construction, utility relocation, guideway construction, temporary by-pass road construction, re-grading of 112th Ave. SE for the road-over-rail segment, and sound wall installation. These construction activities will occur at the same time of construction is happening adjacent to Bellevue Way SE.

Construction activities on 112th Ave SE began in summer 2017 with utility work and included the closure of SE 15th Street (July 2017) for approximately 3 years. Starting in spring 2018 construction will include:

  • Building a temporary bypass road along the west side of 112th Ave SE adjacent to the Bellefield Residential Park
  • Constructing a road-over-rail segment north of SE 15th Street that allows for the guideway to cross from the east side to the west side of 112th Ave SE 
  • Realigning SE 15th Street north of its current location and adding a traffic signal at the new intersection.

What is the South Bellevue Station?

The South Bellevue Station is part of East Link. The station will be located on Bellevue Way Southeast at the current South Bellevue Park and Ride site. The elevated station will include bus and paratransit transfer facilities and 1,500 parking stalls. The station is anticipated to open for service in 2023.

How long will construction of East Link in south Bellevue take?

Construction of East Link in south Bellevue (from I-90 to 112th Avenue Southeast) is estimated to take approximately five years. Construction is expected to begin in Spring 2017 and the most notable construction activity will be the closure of the South Bellevue Park and Ride. Restoration of Bellevue Way SE and 112th Ave SE is anticipated in 2020.

With the South Bellevue Park and Ride closed, where are there alternate commuter parking lots?

The South Bellevue Park and Ride closed May 30, 2017. Sound Transit has established (temporary) alternate commuter parking lots are various locations – many within Bellevue.

Commuters are asked not to park within Bellevue neighborhoods.

If you would like help in planning your commute, please contact Choose Your Way Bellevue.

What changes area happening with the ST550 bus service?

The existing northbound bus stop on the east side of Bellevue Way SE will remain throughout East Link construction. A temporary bus stop has been installed on the west side of Bellevue Way to serve southbound buses will be located just north of 112th Ave SE.

The Mercer Island Park and Ride will be the only park and ride that will be served by ST550 when the South Bellevue Park and Ride is closed.

What other Sound Transit service changes will be made during the construction of the South Bellevue station?

ST550 buses will continue to serve Bellevue Way SE adjacent to the South Bellevue P&R throughout construction.

In preparation of East Link construction, ST555/556 will be re-routed off 112th Avenue SE (this change was part of King County Metro’s September 2016 Service Change).

Routes ST555/556 will continue to serve Bellevue Way SE and the Bellevue Transit Center. As part of the September 2016 Service Change, four (4) more trips were added to ST555/556 routes.

In March 2016, Sound Transit added 12 trips to the ST Express Route 554 with service from Issaquah to Seattle to operate 15-minute peak service. Also in March 2016, a new route, ST 541/Overlake was added.

ST 560 will bypass the South Bellevue Park and Ride and go directly to Bellevue Transit Center via I-405.

Paratransit service by King County Metro Access will be moved to the Eastgate P&R.

What King County Metro routes are affected due to East Link construction?

Metro Route 249.  The South Bellevue Park and Ride currently serves as a layover facility for route 249.  The South Bellevue Park and Ride will be closing during East Link construction for up to five (5) years beginning as early as Spring 2017. 

As of September 10, 2016 Route 249 became a clockwise-like loop route through Beaux Arts Village.  This route will also begin using a new southbound bus stop on Bellevue Way SE just north of 112th Avenue SE instead of stopping in the South Bellevue Park and Ride in the southbound direction.  

King County Metro Transit initiates services changes twice a year - in March and September.

What’s the timing and funding for the Surrey Downs Park Master Plan?

Surrey Downs Park is currently closed for construction which began in April 2018 and is expected to be complete by the end of the year. Construction is dependent on Sound Transit's schedule for light rail construction.

To subscribe to receive project updates via email/text, click here.  

An update to the Surrey Downs Park Master Plan was approved by the City Council in Nov. 2015. The update was needed as a result of the East Link
112th Avenue Southeast alignment being decided.  

Some of the key updates reflected in the Master Plan include:

  • Conversion of programmed sports fields to a play meadow available for pick-up games and practices.
  • Vehicle access from 112th Avenue Southeast has been relocated to Southeast Fourth Street.
  • A series of large, sculpted earth berms with trails and pedestrian overlook were added.
  • Two-tiered retaining walls along 112th Avenue were designed to:
    • Create a green front door to the park for passing motorists and pedestrians consistent with the landscaped corridor desired throughout the length of the light rail corridor in Bellevue.
    • Provide a pleasant experience for the park user. This includes allowing visitors to experience territorial views to the east and southeast without feeling walled in and to allow visitors, especially young children, the opportunity to see the passing trains.
    • Be a good neighbor to residents living near the park. 

What noise mitigation is happening for Surrey Downs Neighborhood as a result of East Link?

East Link construction noise mitigation: Temporary sound walls (20-foot in height) have been installed at the south tunnel portal (Main St/112th Avenue SE) to reduce noise from construction activities. Sound Transit plans to conduct construction activities during exempt hours; therefore construction mitigation is not required.  Homeowners identified by the City as being directly impacted by construction activities conducted beyond the normal construction hour limits will be offered a noise-reduction product by Sound Transit.

Train operation noise mitigation: Mitigation identified during the noise analysis for East Link recognized the need for noise mitigation along 112th Avenue SE adjacent to Surrey Downs Park. Mitigation includes sounds walls at the north and south ends of the park and landscaped terraces with low retaining walls through the parks center area. Once Sound Transit’s contractor releases its work schedule,  the timing of the demolition of residential structures along 112th will be better known as will the timing of the building the permanent sound walls.

When will the fences bordering Surrey Downs Park be installed?

As part of the additional noise analysis performed during the Park planning stages, it was noted that, while not required of Sound Transit, installation of fencing surrounding the Park could provide reduction in sound levels. The City’s Parks & Community Services Department is working to have a new boundary fence installed before construction starts in the Park.  Staff from the City’s Parks & Community Services has initiated conversations with the Surrey Downs Park Committee regarding outreach efforts and will be contacting Park neighbors regarding installation of fences bordering the park.

Where will construction equipment staging be located?

Most of the staging will occur at the South Bellevue Park-and-Ride site. Additional staging will also occur adjacent to the alignment along Bellevue Way Southeast and 112th Avenue Southeast and within the median of I-90.

Who did Sound Transit hire as its contractor?

On October 27, 2016, the Sound Transit Board of Directors authorized the contract with Shmmick/Parsons Joint Venture. The South Bellevue segment has been procured using the "design/build" method.

Where will Sound Transit’s contractors park?

Sound Transit’s contractors will park within their owner designated area as this is a requirement per Sound Transit’s contracting.

What work will Sound Transit do within Enatai Beach Park?

Sound Transit intends to use an area within Enatai Beach Park underneath the I-90 roadway to perform seismic retrofit work on the East Channel Bridge and stage construction equipment on the I-90 portion of the East Link light rail project.

The majority of work for East Link will occur underneath I-90, outside of the improved area of the Park, on freeway land owned by Washington State Department of Transportation (WSDOT).

Starting as early as October 13, 2017, Sound Transit crews will begin to mobilize (stage equipment and trailers) at the Park. Crews will use a portion of the existing Park and parking area as its construction zone. Work involves seismic retrofit activity along the East Channel Bridge. Details and map in a Sept. 27 Construction Alert.

Following Sound Transit's East Link work, King County Wastewater Division will be placing a new sewer pipeline within a similar area underneath I-90 with an underground pipe connection through Enatai Beach Park to an existing sewer line in Lake Washington that serves Bellevue households east of the Park.

What is King County's sewer upgrade project?

King County WTD needs to replace sewer pipes that serve areas in North Mercer Island, the southwest portion of Bellevue near Enatai Beach, and the Town of Beaux Arts Village . This pipeline carries wastewater from the North Mercer Island Pump Station to the Sweyolocken Pump Station in Bellevue.

What is the Bellevue Way Southeast Southbound HOV Lane project?

The City is exploring alternatives to widen Bellevue Way Southeast by approximately 20 feet on the west side of the roadway in order to add a new southbound high-occupancy vehicle (HOV) lane to increase capacity for traffic leaving downtown and to improve transit reliability and speed. The City is developing the alternatives by taking into consideration comments heard from individual briefings and open houses with the public.

The project team has been refining design options based on community feedback and working with the Bellevue Transportation Commission and City Council to consider a preferred design option and provide direction on next steps.

In May 2018 the City Council directed staff to defer additional design work on the project until 2021-2022, with construction to follow as funding becomes available in the capital budget. Progress on the project's design reached the 30 percent level of completion and that work would still be applicable once the project resumes.
