The Montlake Bridge will be completely closed to vehicular traffic August 9 through September 3, 2021. Washington State Department of Transportation (WSDOT) will replace the approximately 20-year-old worn out grid deck on the bascule bridge and, concurrently, they will do the expansion joint and mechanical repairs. The goal is for the movable span to continue reliable operation while meeting the growing demands of the ever-denser traffic in northeast Seattle. State Route (SR) 513 (the State Highway that runs through the Montlake corridor to Magnuson Park) is utilized by 60,000 vehicles daily, and projections show that increased demand with planned growth will further stress the worn-out Montlake Bridge area.
To make these extensive repairs, the work requires both a 26-day uninterrupted closure for vehicles, as well as many subsequent weekend closures throughout the fall. Fortunately, the pedestrian and bicycle shared use pathways will be accessible during the 26-day closure, and boat access will remain open as well.
During the fall weekend closures, however, the span will be in the raised position for the mechanical repairs, and no access will be permitted by bridge users (vehicular or pedestrian). Crews will need to access the workspace under the bridge between the bottom of the roadway and the apparatuses that move the span. Boat traffic will not be affected.
