Westbound lanes close tonight, Aug. 7.SEATTLE – Beginning Friday night, Aug. 8, all lanes of State Route 520 across Lake Washington will be shut down in both directions between Montlake Boulevard and 124th Avenue Northeast for a weekend-long construction closure. The westbound lanes of the highway will also shut down at 11 p.m. tonight until 5 a.m. Friday Aug. 8 for concrete pours.
Contractor crews working for the Washington State Department of Transportation will use the closures to pour concrete as they put the finishing touches on the new West Connection Bridge. The structure will connect SR 520’s existing lanes in Seattle with the highway’s new, six-lane floating bridge when it opens in spring 2016. Eastside Transit and HOV Project crews will also be hard at work over the weekend as they place asphalt on new ramps and stripe the freshly paved lanes east of the existing floating bridge.

Construction of both the Eastside Transit and HOV Project and the West Connection Bridge will be complete later this year. WSDOT continues to focus on replacing the existing, structurally vulnerable floating bridge. Sixty of the new floating bridge’s 77 pontoons are now built, and more of them will be towed to Lake Washington from Aberdeen this month.
