Snohomish County Public Works is proposing widen Alderwood Mall Parkway from 168th St SW to the SR 525 ramps to five lanes, including a center turn lane. It will also add new shoulders, bike lanes, sidewalks, gutters, curbs, drainage facilities and new traffic signals at the SR 525 ramps intersection. The county is also extending the sidewalks to 164th St SW with a separate project.
This project is currently in the engineering design phase and will require environmental review and potential right-of-way acquisitions. Construction is tentatively scheduled for 2023.
Single lane closures will be utilized during construction and business access will be available during the project.
The project cost is TBD and will be funded by the Snohomish County Road Fund, Mitigation Funds, and Surface Transportation Program (STP) Funds.
