Prep for extra travel time this weekend with the closure of I-405 through downtown Bellevue. The closure is due to the construction of the Sound Transit East Link Light Rail. 405 southbound will be closed, as will several ramps and interchanges, which also means delays on I-90, SR520 and surrounding streets.
The closures will begin tonight (Friday) at 10 p.m. and continue through 5 a.m. Monday. Next weekend, August 16-18, it will begin again Friday, but this time on the northbound I-405 side.
The two giant weekend closures are to spare would what otherwise be 20 weeks (!) of weekday night time closures.
