We've reached our 100% Design Milestone!

Thank you to all who participated in our outreach throughout the planning and design phases for the MLK Protected Bike Lane project. We appreciate your input on the design concepts. The final design includes additional pedestrian improvements to the intersection of S Judkins and MLK Jr Way.

We will move into construction as soon as summer 2022, and work is scheduled to be complete in time for the opening of the Judkins Park Link light rail station in 2023.

Project Overview

This project began in 2020 following outreach for the citywide Bicycle Master Plan Implementation Plan back in 2019. We heard loud and clear a need for more connections in Southeast Seattle, especially heading north and south. This community process helped identify MLK Way Jr Way as a top priority citywide. SDOT is building a protected bike lane on each side of Martin Luther King Jr Way S between the Judkins Park and Mt Baker Link light rail stations (S Judkins St to Rainier Ave S).

The purpose of this project is to improve safety for people walking, biking, and driving, and create better connections to transit and to destinations between Mt. Baker Station and the future Judkins Park Station. Once the project is complete, a route of protected bike lanes, the I-90 bike path, and neighborhood greenways will allow for safe and comfortable cycling trips between Mt Baker and Downtown Seattle, as well as the neighborhoods in between.

Project Needs

MLK Way has been identified as a high-priority corridor for meeting the following transportation and community needs:

  • Provide a better north/south bike connection in southeast Seattle
  • Contribute to the City’s Vision Zero goal to end traffic deaths and serious injuries
  • Provide neighborhood connections to the future Link light rail station

Conversations with community members and other stakeholders, as well as technical analyses, have informed our current project plans.

Project elements along MLK Way include:

  • Protected bike lanes on both sides of MLK
  • Rechannelization to create safer and streamlined conditions for all road users
  • Changes to parking to support bike lane installation while providing access to local businesses
  • New roadway paint to improve safety conditions for bikes
  • Safer conditions for pedestrians, including widened sidewalks and crosswalks

Benefits

  • Connect people to transit and schools: This will be an important connection to both light rail stations as well as the I-90 Trail, Franklin High School, and the Metro Transit Center. The I-90 Trail is a regional connection that will improve access to downtown and the region's growing trail network from Southeast Seattle.  

  • Improve safety for people who walk, bike, and drive on MLK: This section of MLK Way has high rates of speeding, head-on collisions, and off-the-road collisions compared to other parts of the city. Redesigning the street will help to reduce speeding and make the street safer, more predictable, and more comfortable for everyone.  

Protected bike lanes uniquely provide a separate, protected space for people biking that is differentiated from motor vehicle travel lanes, parking lanes, and sidewalks. The purpose of this new infrastructure is to improve neighborhood connectivity, increase mobility and transportation options, and enhance both pedestrian and bike safety in southeast Seattle.

We're focusing on the section of Martin Luther King Jr Way S between the Judkins Park and Mt Baker light rail stations (S Judkins St to Rainier Ave S). We had been studying the feasibility of a protected bike lane on MLK between Rainier Ave S and S Henderson St., but we put a pause on that portion of the project in response to the significant decline of revenues for the City and our funding partners related to the COVID-19 crisis. Read more on the SDOT blog.

As part of the latest Bike Master Plan Implementation Plan, Martin Luther King Jr Way S was identified as an important southeast Seattle bike connection. SDOT uses the following criteria when prioritizing projects: safety, connectivity, equity, ridership, and livability, as well as policy directives, community interest, and geographic balance.

Final Project Design

S Judkins St and MLK Jr Way S improvements 

Improvements at this intersection include:

  • bike lane located between travel lane and sidewalk on west side of street
  • bike lane located between parking and sidewalk on east side of street
  • new ADA curb ramps at all four corners 
  • markings for people biking, walking, and driving

I-90 Trail and MLK Jr Way S improvements

At the I-90 trail connection, we've designed raised protected bike lanes and bus islands to accommodate people biking, walking, taking the bus, or driving. The shared bus stop will reduce interactions between bikes, cars and buses on the corridor, providing improved safety and predictability for all users, and will help keep transit moving to improve travel time for people riding buses.

The design elements include:

  • bike lane transition from street grade to sidewalk grade with slow down line markings
  • bike lane located between travel lane and sidewalk
  • sidewalk level pedestrian crosswalks cross the raised protected bike lane
  • markings for people biking, walking, or using transit
  • passengers board and alight (exit) into the bike lane
  • bikes must yield to passengers boarding/alighting

In addition to the design features listed above, the project will also add right turn bicycle ramps to access the I-90 Trail. Unique bus stop announcements will be added to buses serving the shared stops. These announcements will alert exiting passengers to "watch for bikes when exiting the bus" as buses approach the shared stops.

S Massachusetts St and MLK Jr Way S improvements

Currently, this street has one travel lane in each direction, a center turn lane, and parking on both sides. There are sidewalks present, but no bike lanes. Our proposed design introduces protected bike lanes to both sides of the street. Other design elements include:

  • Protected bike lanes on both sides of the street
  • Green pavement markings to highlight where cyclists will be present
  • Turn boxes to help cyclists safely make left turns
  • Bike signal at S Massachusetts St for southbound bike lane 
  • Shared raised protected bike lanes and bus stops where buses remain in travel lane
  • Removed parking on the east side of the street
    • Preserved parking on the west side is closer to community centers and businesses

S Bayview St and MLK Jr Way S improvements

This corridor has four travel lanes and a center turn lane. There are no bike facilities, and the sidewalk is missing on the east side of the street between S Bayview St and S McClellan St. Our proposal for this corridor will remove two travel lanes and includes:

  • Protected bike lanes on the both sides of the street
  • A protected multiuse path on the east side of the street, south of S Bayview St with a detectable strip between cyclists and pedestrians.
    • This path will be separated from vehicle traffic by a concrete barrier
  • Drainage and pavement repairs and upgrades
  • Upgraded curb ramps
  • Green pavement markings to highlight where cyclists will be present

S McClellan St and MLK Jr Way S improvements

Currently, the street has four travel lanes that become a left turn lane at S McClellan St. This corridor is heavily used by Metro buses accessing the current location of the Mt Baker Station. Our proposed design for this corridor will remove two travel lanes and includes:

  • Protected bike lanes on both sides of the street
  • A protected multiuse path on the east side of the street north of S McClellan St, with a detectable strip between cyclists and pedestrians.
    • This path will be separated from vehicle traffic by a concrete barrier
  • Openings in the proposed bike lane to maintain access to businesses and the transit center
  • Green pavement markings to highlight where cyclists will be present
  • Other pedestrian improvements that were a part of the Accessible Mount Baker Project

The near-term improvements from the Accessible Mount Baker Project have been merged with the MLK Protected Bike Lane Project. To see full details on the Accessible Mount Baker Project, please visit the project webpage. Improvements in this area include:

  • New and widened curb bulbs and crosswalks to create shorter crossings
  • Widened and repaired sidewalks for additional sidewalk space
  • Right turn restrictions from Rainier to MLK
  • Protected bike lanes that connect to the Mt Baker Light Rail Station
