36th and 35th Avenues W

Update - November 2022

Preconstruction field work, including utility relocation and tree trimming, will begin this month.


This two-mile corridor improvement project is a joint effort between the City of Lynnwood and Snohomish County. The County’s section of the project is between 164th St SW and Highway 99.

The planned improvements to the existing two-lane roadway include the addition of a two-way center turn lane, sidewalks, bike lanes, bus pullouts, streetlights, landscape features, and stormwater drainage facilities.

The project has reached full funding with the addition of a $3.3 million grant from the Washington State Transportation Improvement Board. As a result, the entire project will be completed in one phase and construction is scheduled to begin in 2023.


  • 2018-2019: Environmental survey, geotech study, design, right-of-way acquisition
  • 2020-2022: Right-of-way acquisition, develop final design
  • 2023: Construction

The process of developing road projects takes several years. Many factors must be considered, including: location of homes; public right-of-way; stormwater runoff, drainage and water quality; wetlands and buffers; hilly terrain; sight distance; soils; traffic volumes; accident history; vehicle and pedestrian access; location of utilities; and information that residents provide about the area.


  • $3.3 million grant from the Washington State Transportation Board
  • $2.58 million grant from the federal Surface Transportation Program
  • $3 million loan from the Washington State Public Works Trust Fund
  • Developer mitigation fees
  • Snohomish County Road Fund
