36th and 35th Avenues W

Update March 2021

Construction of this project has been divided into two phases moving forward. Phase I will be constructed from 164th St SW to 156th St SW on 35th/36th Ave W. Phase II will be from 156th St SW to 148th St SW on 35th Ave W.

Project Description

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 and will be constructed in two phases:

  • Phase I – 164th St SW to 156th St SW on 35th/36th Ave W
  • Phase II – 156th St SW to 148th St SW on 35th Av

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 for both phases.


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

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. Full funding for construction has not yet been obtained.
