Weekday construction traffic impacts: Monday, July 9 – Friday, July 13

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.

Monday-Friday 7 a.m. to 3 p.m.: As needed, in order to complete utility work and facilitate wall construction, Sound Transit's contractor may close one southbound lane of 112th Avenue Southeast, between Southeast 8th Street and Bellevue Way Southeast.

Night work at I-90 in Bellevue

Construction area map for long span aerial guideway.

Long span aerial guideway construction

What to expect: Beginning the week of June 17, crews started working night shifts within the I-90 corridor. Night work is necessary to finish the elevated columns and construct the light rail guideway. Work activity will initially be focused near columns four and five (see map). Crews will construct the pier table (the structure on top of column that supports the bridge deck) at column five and begin installing a form traveler crane that will be used to construct the long span segmental bridges.

Work hours: Overnight, Sunday-Thursday (Friday morning). Since much of this work will occur over I-90 and I-90 ramps, crews will close lanes below the work zone, restricting traffic flow on I-90.

Noise: There will be noise from cranes, hydraulic pumps, steel beam erection, concrete trucks and associated equipment while crews set steel falsework, construct forms and place concrete in forms to build the bridge span. Vehicles will utilize broadband backup alarms.

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.
