Drivers can expect overnight closures and some full weekend closures during construction. Crews will build the new bridge to the east of the existing bridge. The existing bridge will remain open during construction.
We will maintain bicycle and pedestrian access on the SR 529 corridor during construction, with the exception of some night and weekend closures. Crews may occasionally use “strolling slow-downs” during the day, but will not be allowed to delay traffic for longer than 10 minutes at a time. Pedestrians and bicyclists will wait in a protected location away from traffic and work activities during those closures.
Please note that these are estimated dates and are subject to change as construction progresses:

In stage 1, crews will first build a temporary work platform next to the existing bridge. Then they'll build the foundation, substructure and superstructure for the new bridge. All traffic will continue using the existing bridge.
Stage 2: February 2012 - April 2012

In stage 2, crews will build the new alignment of SR 529 at either end of the bridge. Northbound traffic will be moved to the new bridge.
Stage 3: April 2012 - February 2013

In the final stage of the project, crews will remove the old bridge and complete final paving and striping in the project area. All traffic will be moved to the new bridge.
How will construction affect marine traffic?
Beginning Aug. 1, 2010, the Ebey Slough Bridge will no longer open for marine traffic. The Coast Guard will alert mariners to this change. Affected vessels should use the Snohomish River for upstream travel.
Small watercraft will not be affected except when safety is an issue because of construction activities. Contractor crews working for WSDOT will have a boat in the water during working hours to alert boaters to any potential safety hazards upstream of the Marysville boat launch.
