Long-term closure on 110th Ave NE scheduled to begin in October

This fall, Sound Transit will begin a long-term closure of a portion of 110th Avenue Northeast between Northeast 4th and Northeast 6th streets. The closure is needed to build the Link light rail north tunnel portal near Bellevue City Hall.

Beginning in early October, the closure on 110th Avenue Northeast will occur in multiple phases:

  • Phase 1 (early-October 2017 to approximately spring 2018). Scheduled to last about nine months, phase 1 requires the closure of all lanes on 110th Avenue Northeast illustrated in the work area graphic. Access to the City Center Plaza parking garage will be maintained.
  • Phase 2 (approximately spring 2018 – winter 2018). One lane of traffic on 110th Avenue Northeast will be reopened in both the north and southbound direction.
  • Phase 3 (approximately winter 2018 – spring 2019). Phase 3 again requires a full closure of all lanes on 110th Avenue Northeast in the work area as utilities are reinstalled and the roadway restored.

What to expect

  • Work will occur between 7 a.m. and 6 p.m. Monday - Friday.
  • Sidewalks will be closed along the east side of 110th Avenue Northeast adjacent to the work area and on the south side of Northeast 6th Street. A temporary mid-block crosswalk will be added just south of the work area to facilitate pedestrian access across 110th Avenue Northeast.
  • A uniformed police officer will direct traffic as needed.
  • The Bellevue Transit Center will remain open.
  • Barriers and signage will prohibit vehicles and pedestrians from entering the work zone. Detour signage will be in place.
  • The loudest activities will occur at the beginning of the closure when vacuum trucks are used to remove soil and safely expose underground utilities. 

Background

Last summer, Sound Transit's tunneling contractor closed a larger portion of 110th Avenue Northeast to prepare the soil underneath the roadway for tunneling and construction of the north tunnel portal.

This fall's closure footprint is similar, but smaller compared to what was previously in place. City Center's parking garage access from 110th Avenue Northeast will be maintained, whereas it was closed during the previous work.

A look ahead

Sound Transit's contractor expects regular weekend closures to continue into November. Upcoming closures during the weekends of Sept. 23-24, Sept. 30-Oct. 1 and Oct. 7-8 are expected to be similar to this coming weekend's closure.

Tree removal along 112th Avenue Southeast 

Beginning as early as the week of Sept. 18, Sound Transit's contractors will begin clearing trees and understory vegetation in the Sound Transit work zone along 112th Avenue Southeast adjacent to Surrey Downs Park. Trees located where the light rail route will be built need to be removed in order to build the project. Sound Transit has worked closely with the City of Bellevue and Washington State Department of Ecology in development, review and approval of plans for clearing trees and understory vegetation. 

The preservation of trees to the maximum extent feasible has been a primary project goal throughout project design and into construction. Throughout the corridor, trees that are in close proximity to the work zone but not be negatively impacted by construction or light rail operations will be preserved with protective fencing.

Winters House protection and monitoring

This work was originally scheduled for early August, but it was delayed. As early as next week, crews will begin implementing a protection plan for the Winters House. The Winters House will be surrounded on three sides with scaffolding which will then be wrapped with white shrink wrap, providing a protective barrier on the exterior of the house. Fans, de-humidifiers and temporary heating will be installed to maintain airflow and help maintain dry conditions. Vegetation adjacent to the Winters House will be removed so crews can install the scaffolding that will support the exterior protection wrap.

Crews will install monitoring equipment and monitor for settlement, vibration and cracking. Regular monitoring of Winters House will continue throughout East Link construction.

Reminder: Southbound closure on 112th Avenue NE

Correction: Last Friday's construction alert incorrectly stated the 112th Avenue Northeast southbound closure would begin on Sept. 6.

On Saturday, Sept. 9, 112th Avenue Northeast will be closed to southbound traffic between Northeast 4th and Northeast 6th streets so that construction crews can perform work on an underground utility line.

Map showing detour for construction work on 112th Avenue in Bellevue.

What to expect

  • Work hours: The closure will be in place from 9 a.m. – 9 p.m.
  • Noise: Noise will be generated as crews excavate through the roadway, install temporary shoring and restore the roadway upon completion.
  • Duration: If the work takes longer than one day to complete, crews will revisit the site on Saturday, Sept. 16 to finish with the same road closure and work hours in place.
  • Detour: Southbound traffic on 112th Avenue Northeast will be detoured to 110th Avenue Northeast using Northeast 6th Street. Detour signage will be in place. A uniformed police officer will be present to help direct traffic.

Bellevue light rail tunnel update

Sound Transit contractors began mining the new light rail tunnel under downtown Bellevue in February. They started at the intersection of Main Street and 112th Avenue Northeast and are now more than 500 feet into their 2,000 foot trip. The miners are currently under 110th Avenue Northeast and are headed north to the future Bellevue Downtown Station.

Construction crew excavate the downtown Bellevue light rail tunnel.

Several weeks ago, a time-lapse camera was installed in the tunnel to get an up close look at how it's done. Check it out.

Drilled shaft work begins in downtown Bellevue

Picture of Central Bellevue construction areaThis week, Sound Transit’s contractor began drilling shafts in downtown Bellevue to support construction of the elevated guideway.

Typical elevated guideway construction consists of:

  • Drilling shafts for column foundations
  • Installing columns
  • Building the guideway, bridge spans and rail

Nearly 40 columns will be constructed to support the elevated guideway that will cross I-405 and transport riders between the Bellevue Downtown and Wilburton Stations.

The first shaft is being drilled in close proximity to Bellevue City Hall at the corner of NE 6th Street and 112th Avenue NE in the lot currently occupied by Sound Transit’s contractor. Construction crews will then work east, moving towards, and eventually across I-405.

What to expect during drilled shaft work:

  • Work hours: 7 a.m. – 6 p.m., M – F
  • Heavy machinery: Cranes, drilling equipment, concrete trucks and excavators.
  • Noise: Noise will be generated from the drilling, soil removal and installation of steel rebar cages that will serve as reinforcement within the column foundations.
  • Duration: Each shaft is anticipated to take approximately three – five days to drill. There are four sets of shafts in between Bellevue City Hall and I-405 south.

112th Avenue NE southbound closure

On Saturday, September 6, a portion of 112th Avenue NE will be closed to southbound traffic between NE 4th and NE 6th streets so that construction crews can perform work on an underground utility line.

What to expect

  • Work hours: The closure will be in effect from 9 a.m. – 9 p.m.
  • Noise: Noise will be generated as crews excavate through the roadway, install temporary shoring and restore the roadway upon completion.
  • Duration: If the work takes longer than one day to complete, crews will revisit the site on Saturday, September 16 to finish with the same road closure and work hours in effect. 
  • Detour: Southbound traffic on 112th Avenue NE will be detoured to 110th Avenue NE using NE 6th Street. Detour signage will be in place. A uniformed police officer will be present to help direct traffic.
