8th Ave Mobility Improvements

December 12, 2019

What's happening now?

Installation of protected bike facilities on 8th Ave between Pike St and Bell St, and Pine St between 8th Ave and 6th Ave, begins as soon as August 3. Installation will take place over two weekends: August 3-4 and August 10-11, weather permitting. During this work, please expect:

  • Daytime installation August 3-4 and August 10-11. Work will include:
    • Grinding off old pavement markings
    • Striping lanes and adding signage
    • Adding pavement markers, buffer striping, and green material
    • Installing posts
  • Some work may occur during the week of August 5, but it will not impact traffic 
  • Flaggers will be present to guide motorists, people biking and people walking around the work area
  • Access to driveways and alleys will be maintained throughout this work

Please view our construction mailer for more information about what to expect during construction.

The redesigned 8th Ave will include a protected bike lane between Pike St and Bell St, one travel lane, paid parking and load zones, and new bike signals at busy intersection. This project completes a two-way couplet for people biking with the existing 7th Ave protected bike lanes. It will also connect with protected bike lanes on Bell St and 9th Ave to get people to and from the Westlake Cycle Track and north Seattle neighborhoods, and with bike lanes on Pike St and Pine St to get people to and from greater downtown, Pike Place Market, and Capitol Hill.

This project also extends the Pine St protected bike lane between 7th Ave and 8th Ave, in order to provide a connection to the new facility on 8th Ave.

These improvements are a component of the Center City Bike Network, which is a longstanding city priority to make center city streets safer and more predictable for everyone, have biking be a real transportation choice in our densest jobs center, and to maintain transit priority.

Program Overview

The Center City Bike Network launched in 2015 and developed a network map of better bike streets that separate vulnerable users from traffic, provide safe all-ages and abilities facilities, and maintain transit priority downtown. This network was the product of extensive community engagement, which continued through the One Center City program to make sure any improvements to the bike network were well coordinated and complimentary to the greater transportation network for people walking, driving, taking transit, and delivering goods.

We've made a commitment to build this network of separated bike facilities to make biking a reliable travel choice and calm traffic as more people compete for limited street space. A complete bike network improves Seattle's health and quality of life for people of all ages and abilities.

These protected bike lanes, paving, channelization changes, and signal upgrades in the center city improve safety for everyone and connect the critical missing segments of the center city bike network.

We've already built critical projects that have given Seattle large segments of a basic downtown network, including 2nd Ave, the west end of Pike St and Pine St, and 7th Ave. These go on to connect to additional, built connections like the Westlake Cycle Track, Broadway, and Dearborn St

In 2019, we're going to complete more projects:

Each of these projects will include targeted communications and outreach to affected and nearby stakeholders and communities. More detail on each individual project can be found on their respective websites at the links above. The Department of Neighborhoods is partnering with the Department of Transportation to provide greater outreach and community engagement.

Protected Bike Lanes

You'll soon see protected bike lanes on 9th Ave, 8th Ave, Pike St, 2nd Ave Ex, S Main St, and 5th Ave in addition to the lanes already out there.

Protected bike lane projects include new bike lane markings, plastic posts, signs, and bike signals. Please note that the S King St project is a neighborhood greenway.

Since protected bike lanes were installed on 2nd Ave, crashes are down and bike ridership is up.

In general, protected bike lanes separate people biking from moving car, bus, and truck traffic so they make the street safer, predictable, and comfortable for everyone. Cities around the world are increasingly embracing protected bike lanes that separate people on bikes from people in cars by using physical barriers such as posts, parked cars or simple landscaping.

Seattle's center city network of protected bike lanes aims to:

  • Improve safety and predictability by separating all modes of travel
  • Expand connectivity throughout downtown and the rest of Seattle as our city continues to grow
  • Boost business by offering more travel options for getting to them
  • Promote physical activity and increase ridership
  • Provide affordable travel options
  • Maintain transit priority on Seattle streets


Some parking changes will accompany the street redesign and new lanes. Our goal is to work with all adjacent building and business owners to understand parking needs and maintain on-street loading zones are on most blocks. Access to alleys, off-street parking garages, and loading bays would be maintained.
