Alderwood Mall Parkway Corridor Improvements

Description

Snohomish County Public Works proposes to widen Alderwood Mall Parkway from the 16800 block to the SR 525 northbound ramps. The project would widen the road to five lanes, including a center turn lane, raised bike lanes, sidewalks, gutters, curbs, drainage facilities, three fish passage culverts, and new traffic signals at the SR 525 northbound ramps intersection. Snohomish County is also planning to overlay Alderwood Mall Parkways from 164th St SW south to the Lynnwood city limits at the same time as the widening project.
