The eastbound ramp from Montlake Boulevard to the highway will also close.
All other ramps will remain open, as will all westbound lanes of SR 520.
Crews working on the West Approach Bridge North
Project will use the closure to cut a trench across the highway’s eastbound lanes in preparation for installation of a new sewer line.
Drivers who intend to travel to the Eastside from Seattle during the closure should plan to take Interstate 90 or an alternate route around Lake Washington.
