9th Ave N Mobility Improvements

June 21, 2019

What's happening now?

This summer, we're building projects that will make critical connections for people biking to and through South Lake Union, Denny Triangle, Downtown, Capitol Hill, Pioneer Square, and Chinatown-International District.

For the 9th Ave N project (which includes one block of Bell St), we'll install new protected bike lanes between 8th Ave and Harrison St. The redesigned 9th Ave N and Bell St will include one general travel lane in each direction, paint-and-post bike lanes, no center turn lane, minor parking removal, and a new 4-way stop at 9th Ave N and John St.

This project connects the new 8th Ave and existing 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. A private developer will extend the protected bike lanes one block further, between 7th and 8th, later this year. In a few years, Bell St between 2nd Ave and Denny Way will be upgraded as part of the Bell St mobility improvements project.

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, to allow biking to be a reliable transportation choice in our densest jobs center, to improve public health and equity, and to maintain transit priority.

Community outreach work on this project is ongoing. If you want to get in touch with us, please call 206-684-8105 or email ccbike@seattle.gov. Thank you.

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 thecritical 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 N, 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 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 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

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, calm 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 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.
