The closure — from 5 a.m. on Saturday, Oct. 24, to 5 p.m. Sunday, Oct. 25, will allow WSDOT maintenance crews to begin safety upgrades to the Montlake Bridge, including replacement of its aging metal decks.
Weather-permitting, crews this weekend will also intermittently close single lanes along East Park Drive East, along westbound Lake Washington Boulevard East between 24th Avenue East and Montlake Boulevard and along northbound and southbound Montlake Boulevard between East Hamlin and Roanoke streets, to complete paving activities.
During the weekend closures, the SR 520 mainline will remain open, including its westbound off-ramp to Lake Washington Boulevard and a single lane of the eastbound off-ramp to Montlake Boulevard.
Drivers can access Montlake using the westbound SR 520 off-ramp to Lake Washington Boulevard, the open lane of the eastbound SR 520 off-ramp to Montlake Boulevard or via the University Bridge.
The Montlake Boulevard U-turn at East Hamlin Street for Interstate 5 access will remain open.
Bicycle and pedestrian access across the west side of the Montlake Bridge will remain open.
Freeway transit stops will remain open, but other buses will be rerouted around the Montlake area.
Marine traffic will be restricted. There will be no Montlake Bridge openings for boats between 7 p.m. and 7 a.m. The bridge’s south span will open for boats (with one hour’s advance notice) between 7 a.m. and 7 p.m. both Saturday and Sunday.
Also, eastbound Interstate 90 will also be down to one lane from this weekend . As they have done in the past, contractor crews with the I-90 Two-Way Transit and HOV Operations project will reduce eastbound I-90 traffic to one lane just before the Mount Baker Tunnel from 11 p.m. Friday, Oct. 23, to 5 a.m. Monday, Oct. 26. Drivers will then be rerouted to the express lanes.
Similar eastbound I-90 weekend work earlier this year resulted in added congestion in both directions of I-5. The Sounders are also playing their final regular-season home match at 4 p.m. Sunday, Oct. 25.
