From 11 PM on Friday evening, November 16, through Monday, November 19 at 5 AM, the 520 floating bridge will be closed from Montlake Blvd to the I-405 interchange in Bellevue. WSDOT will do maintenance projects and at the same time the Montlake Bridge will get its annual bath. The left lane of the Montlake Bridge will be closed in each direction from 6:30 to 11:30 AM on Sunday morning, November 18. Large “vactor trucks” will do the noisy work of cleaning out the muck that accumulates in the large pits under the bridge counterweights. For the weekend, expect increased traffic on I-90, slowing on I-5 and heavy traffic on Sunday afternoon before the Seattle Sounders game which starts at 6 PM.
