Crews will close all lanes of state Route 520 from Montlake Boulevard to Interstate 405 at 11 p.m. tonight, June 20, including all connecting ramps in the work area.

Crews will use the closure to continue pouring concrete for the roadway deck on the new West Connection Bridge. In addition, crews will place up to 10,000 tons of asphalt for the new eastbound SR 520 lanes, as part of the Eastside Transit and HOV Project.
All lanes are scheduled to reopen at 5 a.m. Monday, June 23.
