“Missing Link” Bike Route Study on NW Market St - Leary Ave NW - 17th Ave NW

August 27, 2024

What's Happening Now?

We’ve reached 30% design for the “Missing Link” Bike Route Study on NW Market St- Leary Way NW – 17th Ave NW and are excited to share this updated design! Our finalized initial concept at 30% design can be viewed via our full roll plot and 30% Design Documents. You can also read our 30% Fact Sheet.

To learn more about the design changes we made based on community feedback from 10% to 30%, please read about our changes from 10% to 30%. To learn more about what we heard during our 10% design outreach, you can read our outreach summary here.

Thank you to everyone who shared feedback on 30% design on the Feedback Form. We will continue to meet with community and get feedback throughout the design process. 

Background

People out and about on Ballard streets

Councilmember Dan Strauss and Mayor Bruce Harrell requested that SDOT study this route as an option for connecting the Burke-Gilman Missing Link with an all ages and abilities bicycle facility through Ballard along NW Market St, Leary Ave NW, and 17th Ave NW. You can read more details on the original request from Councilmember Dan Strauss’s blog, which can be found here.  

The Burke-Gilman Trail Missing Link is the long-planned multi-use trail safety improvements along 1.4 miles of Salmon Bay east of the Ballard Locks connecting the two existing sections of the Burke-Gilman Trail in Ballard.

SDOT has a 100% design for a proposed route along Shilshole Ave NW, however construction along this route has been paused due to ongoing litigation for over 25 years. This route remains an option if these legal challenges are resolved. Please see this website for more information on the Shilshole alignment.

Moving forward with designs for the Market/Leary/17th route will help us understand how this project can connect the Burke-Gilman Trail, improve connectivity in the bike network, as well as potential impacts.

We've launched a design and public engagement process to study what an alternative “Missing Link” connection using 17th Ave NW, Leary Ave NW, and NW Market St would look like and mean for community members and businesses. 

Route

The newly proposed route would extend along NW Market Street two blocks east from 24th Ave NW and then run along Leary Ave NW to 17th Ave NW where it re-joins the Shilshole Route as designed to connect to the Burke Gilman Trail.

Project Elements 

  • A 10 ft wide minimum and .6-mile-long multi-use trail connection as part of the Burke Gilman “Missing Link.” Multi-use trails allow for two-way, off-street use for people walking, biking, rolling, and using other mobility devices. This trail would provide convenient access to businesses, residences, and other points of interest along Market, Leary, and 17th for all ages and abilities. Visit our Shared Use Design Standards webpage to read more about the variety of bike facilities we build. 
    • Only the south side of Market, southwest side of Leary, and west side of 17th would be reconstructed as part of this proposed design to move the curb line out. 
  • Safety improvements including:
    • New ADA-compliant curb ramps
    • Additional curb bulbs
    • Raised crossings at some intersections 
    • Traffic signal updates to accommodate trail crossings
  • Loading/parking lanes along the southwest side of Leary would be preserved. Around 50 additional back-in angle parking spots could potentially be added on NW 48th St and 22nd Ave NW and Leary Ave NW with the proposed operational changes to those roads.   
  • Replacing all existing trees that would need to be removed to accommodate the additional space for a trail connection at a 3 to 1 ratio within the project area. At this point around 30 trees would be impacted and require around 105 replacement trees.

17th Ave NW 


The graphics below show proposed plan views and cross section of 17th Ave NW between Leary Ave NW and Shilshole Ave NW, before and after improvements looking north. 
Improvements along this section of the route include: 

  • The 10’ multi-use trail standard across this design.
  • Increased sidewalk coverage, including a 6’ sidewalk on the west side of the street. The existing east side sidewalk would remain as it currently exists with upgraded ramps at the crossings. 
  • Parking would be retained along the west side of 17th Ave NW.
  • The crossings of both NW 48th Street and Ballard Ave NW would be raised. 
  • Additional parking would be designed on NW 48th Street as back-in angle with eastbound traffic only permitted from NW 48th Street onto 17th Ave NW.

Leary Ave NW Improvements

Improvements along this section of the route include: 

  • The 10’ multi-use trail standard across this design, and wider than 10' where possible.
  • Increased sidewalk coverage, including an 8 to 10’ sidewalk on the southwest side of the street.
  • A center turn lane between the two driving lanes, and a bus lane on the east side of the street going northbound, consistent with the Route 40 project north of Ione.
  • A 5’ minimum planting strip separating the multi-use trail from the preserved parking lane on the southwest side of Leary Ave NW.

Improvements along this section of the route include: 

  • The 10’ multi-use trail standard across this design. 
  • No changes to the north side of NW Market Street proposed with this project. 
  • An 8’ sidewalk on the south side of the street.
  • Redesigned eastbound bus stop for Route 40/44 with 10 ft wide pedestrian loading area closer to 22nd Ave NW. A 5’ planting strip where additional street trees will be planted, separating the multi-use trail from the vehicular travel lane.
  • Retain existing space for 6’ minimum street cafes on both sides of the street.

Funding

The Seattle Department of Transportation will use existing funds allocated to the Burke Gilman Trail Project to develop 100% design for the Missing Link Connection along Market/Leary/17th . 

Timeline

We’ve reached a finalized initial concept at 30% design.

We have received direction to continue to work towards 100% design. This is the next step along the way to completing a full design. 

Please sign up for our listserv to follow us for next steps on the project. 

We are continuing to collect community feedback on this route via the online feedback form or, through our project inbox.

Public Engagement

Councilmember Dan Strauss held stakeholder meetings in January 2023 and in February 2024 with Bicycle, Industrial, and Commercial interests to receive feedback on this proposed route for completion of the “Missing Link”. The initial feedback he received in 2023 specified both corridor-wide and street-specific design considerations. More details were posted in Councilmember Dan Strauss’s blog which can be found here.  

Additionally, the outreach team has mailed project information postcards to all 3,625 adjacent property owners of record along the route, met individually with business and property owners along the route, conducted multiple sessions of door-to-door flyering along the route, held an early design public meeting, held tabling events at the Ballard Farmers Market and again on the corner of Market and 24th Ave NW during the afternoon commutes on September 5th and November 28th , and completed a community survey that had over 1700 respondents. The results of our year-long engagement process can be found in our outreach summary
