Welcome to the Shoreline 175th Street Corridor Improvements Project online open house!

The City of Shoreline plans to improve 175th Street between Stone Avenue and I-5 to make it easier and safer for everyone. We are working to better understand what’s happening on 175th Street now to inform early design concepts.

  • Scroll down or use the tabs above to read about some of the current challenges and share your thoughts on how we can improve 175th Street!
  • This site will be available from May 21 to June 14. You can visit the site as many times as you wish.
  • Information shared on this site is the same information made available at a May 21 open house.

175th Street Background

175th Street Background

175th Street is one of our busiest roads and connects State Route 99/Aurora Avenue N, Interstate 5, and 15th Avenue NE. Our goal is to make 175th Street easier, safer, and more predictable for people walking, biking, driving, and using transit. For more information, read our fact sheet (Español, 中文, Tagalog) and frequently asked questions (Español, 中文, Tagalog).

Existing Conditions

We are early in the design process. No decisions have been made. Changes to the corridor may include ways to reduce traffic, build sidewalks, and build bike lanes on 175th Street or nearby.

Our team looked at traffic, safety, and existing facilities on 175th Street. Click on the images below to learn more about the existing conditions and current challenges people walking, biking, driving, and taking transit experience.

Other information gathered

Our team also collected information on:

  • Existing Landscaping: To understand landscaping character and how that may affect design.
  • Neighborhood and community information: To understand key characteristics and considerations for the design.
  • Site distance: To understand visiblity and safety for people driving. The team found that site distances are adequate for people driving up to 35 miles per hour (the current speed on the corridor).



Use the map below to identify problems you see on 175th Street. You can also suggest improvements! Consider what you like about walking, biking, driving, and taking transit on 175th Street, what challenges you experience, and what changes you would like to see. Connect with your neighbors and talk about what is important on 175th Street.

Shoreline 175th -120-022-000 - ooh feedback survey

Give us your feedback!
1. We want to know what is most important to you to guide our early design work. For each street improvement topic, please indicate the level of importance to you on a scale of 1 to 5.

1 = Less important to me. I don’t feel that this is worth additional costs or potential impacts
5 = More important to me. I feel strongly that this is needed, even if it involves additional costs or potential impacts

Next Steps

Next Steps

This year, using information we receive during this outreach, we will develop design alternatives to address issues we have heard are important to you. With additional input, we will then develop a preferred concept design in early 2020. You will have several opportunities to provide feedback along the way.

We are talking to people who live along the corridor to see what changes need to be made. We are also talking to local businesses, community organizations, and people who travel along 175th Street. We will keep you informed throughout the design process. We will let you know how your comments influenced the design. If we don’t use your suggestions, we will let you know why.

Project timeline

Throughout the design process, we will be in touch with the community to gather feedback at key points.
