Feedback and study survey

Hello! Thanks for taking the time to complete this study survey.

People use SR 99 for many reasons, and we want to know how to create a corridor that works for your needs and priorities.

Your answers will help us understand what works best for you and your neighbors. It will help WSDOT develop the recommended improvement options for the corridor.

In this survey, the term “corridor” is used to describe the roadway being redesigned, along SR 99 from 212th Street Southwest to Airport Road.

Thank you!


Studies summarize all the uses along a corridor and create a vision for the future. The next 6 questions will help WSDOT understand how you use and your interaction with the SR 99 study corridor.

How often do you travel on SR 99 between 212th Street Southwest and Airport Road, either by motor vehicle, walking, biking, transit or other?

How do you travel on the SR 99 corridor? Select all that apply

What conditions along the SR 99 corridor make you feel unsafe while walking, biking, accessing transit or using a personal mobility device (wheelchair, walker, etc.)? Select all that apply

What trip purposes are you using the SR 99 corridor for? Select all that apply

Do you live or work within a half mile of the SR 99 corridor between 212th Street and Airport Way? (See map)

The SR 99/Lynnwood and Unincorporated Snohomish County Pre-Design Study corridor runs on SR 99, from Airport Road in Everett to 212th Street Southwest in Lynnwood. The study area includes a half-mile buffer around the roadway.

What changes would you most like to see along SR 99 in this area? Select all that apply

The next two sections will use aerial views, street views, and questions to show different ways to improve the road. What changes would you like to see to SR 99 in Lynnwood and unincorporated Snohomish County?

The following section uses the term "shared use paths." Read more about shared use paths (PDF 1.5MB).

The following section uses the term "corridor-wide concepts." Corridor-wide concepts are changes to the roadway, that affect multiple users, for the duration of the SR 99 Study Corridor. In this section, corridor-wide concepts are shown as cross sections, to show trees, sidewalks and width of the road from street view.

Previous community engagement and outreach helped WSDOT develop the corridor-wide concepts in this section.

Both concepts have similarities, including:

  • Bus/right-turn lanes the whole way
  • Space for bikes and people walking on both sides
  • A buffer between people biking and walking and vehicles
  • A median with trees

There are some ways that the concepts differ:

Concept 1 – Shared Use Paths

Graphic showing the SR 99 roadway with six lanes of traffic. The roadway shows red transit-only lanes going in each direction, and two lanes of traffic going in each direction. This graphic shows bike lanes that run parallel to the roadway that go both directions on both sides of the road, bikes and people walking share the same space, and a tree in the road's median.
Concept showing potential changes to the SR 99 Study Area roadway with shared use paths.
  • Bikes are allowed to go both directions on both sides of the road
  • Bikes and people walking share space
  • There is no space for trees on the sides of the road

Concept 2 – Separate Bicycle Lanes

Graphic showing the SR 99 roadway with six lanes of traffic. The roadway shows red transit-only lanes going in each direction, and two lanes of traffic going in each direction. Graphic shows bike lanes that run parallel to the roadway that travel in the same direction as the vehicles, bikes and people walking are separated, and trees in the median and trees separating the roadway from the bicycle lanes.
Concept showing potential changes to the SR 99 Study Area roadway with separate bicycle lanes.
  • Bikes must go in the same direction as the cars
  • Bikes and people walking are separate
  • There is space for trees in the middle and on both sides

Which best shows a corridor that would best meet your needs?

What do you like or dislike about each corridor-wide improvement concept?

To address safety issues this study will include spot treatments, which are targeted improvements implemented at specific locations, such as intersections, between intersections, or at bus stops.

So far, the study has identified spots where we think improvements are needed, based on the feedback we've already received from community groups and local agencies.

This portion of the survey asks you to share your experiences at these locations and any others we may have missed.

The corridor study is broken into six sections, as shown below. Please take some time to share your thoughts and experiences.

Section A: Airport Road to Lincoln Way

The image below shows a section of the SR 99 Study Corridor, from Airport Road to Lincoln Way. The green dots indicate locations we are considering spot improvements. Do you have safety or other concerns about this section of the SR 99 Study Corridor? If yes, what concerns do you have? Did we miss any locations for improvements along this section?

A map shows a section of the SR 99 study area from Airport Road to Lincoln Way. CVS, Home Depot, and Dollar Tree are highlighted along the corridor. Five spot treatments are located along the SR 99 roadway.

A project is planned to install bus lanes from 148th Street Southwest to Airport Road in both directions. Early in the study, the SR 99/SR 525 interchange and 35th Avenue West were identified as needing safety and transit improvements. Currently, we are considering the following options to change the interchange (see map below for options):

  • Converting merge lanes to bus lanes instead of widening SR 99
  • Converting shoulder to pedestrian and bicycle facilities
  • Requiring vehicles to stop before turning onto SR 99 instead of merging without stopping
  • Adding traffic lights at the on and off ramps
  • Removing and adjusting on and off ramps
A map of the SR 99 and SR 525 interchange shows SR 99 on ramps, SR 99 off ramps, and the options for changing the interchange.
