Crews will be hard at work over the weekend as they place asphalt on new ramps and stripe the freshly paved lanes east of the state Route 520 bridge. Beginning Friday night, Aug. 8, all SR 520 lanes across Lake Washington will shut down in both directions between Montlake Boulevard and Interstate 405 for a weekend-long closure.

All lanes and ramps will reopen by 5 a.m. Monday, Aug 11.

Late-night drivers should also prepare for three nights of westbound closures this week — Monday, Aug. 4, to Friday, Aug. 8 — between 92nd Avenue Northeast and Montlake Boulevard as crews pour concrete and put the finishing touches on the new West Connection Bridge. The structure, due for completion this fall, will connect SR 520’s existing lanes in Seattle with the highway’s new, six-lane floating bridge when it opens in spring 2016.
