Sound Transit East Link Light Rail construction to close I-405 in downtown Bellevue

Prepare for delays on the weekends of Aug. 9-12 and Aug. 16-19

By Thomas Charlson

If you plan to travel on either side of Lake Washington on the weekends of Aug. 9-12 or Aug. 16-19, be prepared for significant closures on I-405 that will create long delays region-wide on the surrounding highways and city streets.

Last year Sound Transit's contractor crews built a temporary support structure as part of East Link Light Rail construction in downtown Bellevue. Just like unwrapping a present on Christmas morning, it's time to remove the temporary structure around the brand new concrete light rail structure, which will require two weekends of directional closures of I-405 in Bellevue.
Here is a view of the Sound Transit light rail construction. The temporary support
structure needs to be removed over I-405 in Bellevue.

What to expect for traffic
Between 85,000 and 108,000 vehicles use this section of I-405 in downtown Bellevue, so plan for long traffic delays during the closures. Even if you don't regularly use I-405, the closures will create added congestion on alternate routes like SR 520, I-90, I-5 and city streets.

We need everyone's help to keep traffic moving. Allow extra time to reach your destination and consider using alternate routes through downtown Bellevue. Taking public transit, carpooling, walking or biking may be good options to consider during these weekend closures.
Directional closures of I-405 will be between Northeast 10th Street and Main Street.
