Highway 520 between Montlake Boulevard and Interstate 405 will be closed over the weekend because of construction.
Highway 520 between Montlake Boulevard and Interstate 405 will be closed this weekend from 11 p.m. Friday to 5 a.m. Monday.
The closure is part of the Eastside Transit and HOV project, which will widen Highway 520 to six lanes from Bellevue to Montlake. The project is expected to be completed and the widened highway open to traffic in December 2013.
During this weekend’s closure, crews will work on demolishing the western half of the overpass on Bellevue Way Northeast according to the Washington state Department of Transportation.
The floating bridge and ramps will close all weekend except the 108th Avenue Northeast onramp to eastbound Highway 520, which will remain open. The DOT said those heading to the Seattle Mariners and Seattle Sounders games and the St. Demetrios Greek festival in Montlake will need to find alternate routes.
