Center City Bike Network

July 29, 2020

What's happening now

SDOT installed four major Center City Bike Network projects in 2019! These included projects on 8th Ave and 9th Ave in Denny Triangle, Pike St to Broadway on Capitol Hill, and the South End Connection through Chinatown-International District.

We are planning to start our community outreach work for future projects in early 2020. If you want to get in touch with us, please call 206-684-8105 or email

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

We completed the following projects in 2019:

  • 8th Ave Mobility Improvements Project: Completed in early August, new protected bike facilities on 8th Ave between Pike St and Bell St, and Pine St between 8th Ave and 6th Ave completes a two-way couplet for people biking with the existing 7th Ave protected bike lanes. It also connects 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.
  • Pike St Mobility Improvements Project: Completed in September, the new bike facilities on Pike St between 9th Ave and Broadway connect the existing protected bike facilities in Capitol Hill to the facilities on Pike St in Downtown.
  • 9th Ave N Mobility Improvements Project: This project connects the new 8th Ave and 7th Ave protected bike lane couplet with the existing 9th Ave N protected bike lanes north of Harrison St that lead to the Westlake Cycle Track. The protected facilities on 9th Ave N and Bell St, between 8th Ave and Harrison St were completed in November and provide critical connections to and through South Lake Union.
  • South End Connection Mobility Improvements Project: For the South End Connection Project, we've installed two-way protected bike lanes on 2nd Ave Ext S, S Main St, and 5th Ave S between the existing 2nd Ave protected bike lanes and the S King St Neighborhood Greenway. This project was completed in November.
  • S King St Neighborhood Greenway

Each of these projects included targeted communications and outreach to affected and nearby stakeholders and communities. The Department of Neighborhoods is partnering with the Department of Transportation to provide greater outreach and community engagement.

In 2020, we plan to build the first phase of the 4th Ave Mobility Improvements Project from Madison to Pine streets. 

Protected Bike Lanes

Protected bike lane projects typically include new bike lane markings, plastic posts, signs, and bike signals.

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, making 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 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

In addition to these protected bike lanes, a new Neighborhood Greenway route along S King St and Maynard Ave S will begin construction in summer 2019.

Neighborhood greenways are safer, calmer residential streets for you, your family and neighbors. On streets with low car volumes and speeds a greenway can:

  • Improve safety
  • Help people cross busy streets
  • Discourage cars from using neighborhood streets to avoid main streets
  • Protect the residential character of our neighborhoods
  • Keep speeds low
  • Get people to where they want to go like parks, schools, shops and restaurants

Parking and Loading

Some parking changes typically accompany the street redesign and new lanes. Our goal is to work closely with all adjacent building and business owners to understand parking needs and maintain on-street loading zones.
