In this alert: Nighttime girder installation, weekday construction traffic impacts, and reminder of ongoing closures
Precast concrete girder installation
Girder installation is underway in south Bellevue. Starting last week, crews began installing pre-cast concrete girders. The current phase of girder installation is expected to be completed by the end of this week. Precast concrete girders, measuring 80-120 feet long and each weighing up to 205,000 pounds, will be trucked in and lifted into place using large mobile cranes. Once installed, the girders will serve as the foundation for much of East Link's aerial guideway and station in South Bellevue. Anticipated work hours will be 8 p.m. to 5 a.m. nightly.
Girder installation work area.
Noise/light: Temporary light plants will be used to illuminate the work area. There will be noise from cranes, lifts, light plants and associated equipment while crews set concrete girders. Vehicles will utilize broadband backup alarms. Crane backup alarms are tonal, but they will be used infrequently.
Sound Transit's contractor is permitted to work expanded hours in the I-90 corridor and adjacent to Bellevue Way Southeast, including 24-hour work in this area. The allowable noise threshold is based on average construction noise produced over each one-hour period. There may be moments during an hour when construction noise exceeds the hourly average, but crews will take measures to stay below the average hourly threshold. Please contact East Link outreach with any feedback on nighttime noise. For after-hours issues that need immediate attention, Sound Transit maintains a 24-hour construction hotline.

Anticipated girder installation schedule:
July 25-27: Wednesday-Thursday (Friday morning): South Bellevue Station site
Construction crews will use cranes to place girders between columns.
Weekday construction traffic impacts: Monday, July 30 – Friday, Aug. 3
Bellevue Way Southeast
In order to work in the eastside curb lane while maintaining two lanes of traffic in the peak direction (northbound 6-10 a.m. and southbound 2-6 p.m.) crews will use the 'southbound center lane' as a reversible traffic lane. At times, northbound vehicles will travel in what is normally a southbound lane.
Monday-Friday 6 a.m. to 6 p.m.: Work is set to begin on the light rail trench and guideway adjacent to Bellevue Way Southeast, between the South Bellevue Station site and the Wye at 112th Avenue Southeast. Throughout the project, two lanes will be maintained in the peak direction: northbound in the morning and southbound in the afternoon. Sound Transit's contractor will use cones and lane delineators to guide traffic along Bellevue Way Southeast. Please follow the direction of flaggers and signage to safely access your destination. More info on what to expect can be found at the East Link long-term and ongoing closures page.
112th Avenue Southeast
Monday-Friday 9 a.m. to 4 p.m.: Daily closures of one northbound lane of 112th Avenue Southeast, between Bellevue Way Southeast and Main Street.
Monday-Friday 9 a.m. to 4 p.m.: Daily closures of one southbound lane of 112th Avenue Southeast, between Main Street and Southeast 8th Street.
