Construction of the MLK Jr Way S Safety Project began September 28, 2023 and will continue through Summer 2024. Check out our 100% design plans. Want to stay up to date on construction information? Sign up for our listserv to receive construction updates.

We are updating the street design on MLK Jr Way S to reduce driving lanes, slow down people driving, build new protected bike lanes, widen sidewalks, and add new ADA-compliant curb ramps. These changes will improve safety and access to transit and local destinations for people walking, rolling, biking, and driving between Mount Baker Station and the future Judkins Park Station.

Changes coming to MLK Jr Way S

This project will:

Redesign the road to create more predictable vehicle movements. There will now be one lane in each direction with a center turn lane. The travel lanes will continue to accommodate freight and transit movements.
Install protected bike lanes on both sides of MLK Jr Way S and add new bike detection signals at intersections.
Repaint the road to improve visibility and safety conditions for pedestrians, vehicles, and bicycles.
Repair or widen sidewalks and add or widen crosswalks to better separate pedestrians from traffic.
Add or upgrade pedestrian walk signals and bike detection signals to make people walking and biking more visible to drivers.
Upgrade 30 curb ramps to improve accessibility according to the most current ADA standards
Revise parking while maintaining access to local businesses.

Our project was guided by Seattle’s Vision Zero plan to prevent serious collisions by designing safer streets. This project will help manage driver speeds and encourage more walking and biking. When construction is complete, you will notice the following changes to the street:

Project Description

We are updating the street design on MLK Jr Way S to reduce driving lanes, build protected bike lanes, slow down cars, and create safer pedestrian connections to transit. These changes will improve safety and access to transit for people walking, rolling, biking, and driving between Mount Baker Station and the future Judkins Park Station.

Project Goals

The number one priority of this project is to improve safety for people traveling on MLK Jr Way S. As a major arterial road, MLK Jr Way S poses a higher risk of serious and fatal crashes. In our 2022 High Injury Network assessment, the MLK Jr Way corridor scored high. Our crash data showed that there have been 305 collisions on MLK Jr Way S since 2016, which resulted in 152 people being hurt or seriously injured. Since 2020, there have been two fatalities of people walking on MLK Jr Way S who were struck by vehicles while crossing an intersection at MLK Jr Way S & S Massachusetts St and MLK Jr Way S & Rainier Ave S.

While the speed limit on MLK Jr Way is 25 mph, our data showed that most people drive over 35 mph on this corridor south of S Plum St. This is why redesigning MLK Jr Way S to encourage safer roads and speeds is so important.

This project aims to:

Reduce traffic fatalities and serious accidents
Increase ADA accessibility
Prioritize pedestrian movement
Create safe connections to new transit options
Build a citywide bike network

Learn about how each of these goals are incorporated in the construction plan in the Project Area section of this webpage.

Safety Improvements

Our project design was guided by our Vision Zero Top to Bottom Review and the USDOT's Safe System Approach. This project will help manage driver speeds and encourage more walking and biking. When construction is complete, you will notice the following changes to the streets:

Vehicle travel land reduction: 74% of pedestrian fatalities occur on arterials with more than one lane in each direction. Instead of two travel lanes in each direction between S Holgate St and S McClellan St, there will now be one lane in each direction with a center turn lane. The travel lanes will continue to accommodate freight and transit movements.
Wider sidewalks and crosswalks: In order to better separate pedestrians from traffic and encourage walking, we are widening sidewalks and crosswalks. Additionally, we will add new crosswalks at the south and east crossings of MLK Jr Way S & Rainier Ave S and at the south crossing of MLK Jr Way S & S Bayview St.
Protected bike lanes: Our data shows that 80% of people killed while biking were biking where no biking facility was available. This project adds one mile of protected bike lanes connecting people to destinations like I-90 Trail, Rainier Valley Neighborhood Greenway, Franklin High School, Mount Baker Transit Center, and the Mount Baker and future Judkins Park Link light rail stations. We will add bike detection at the following intersections: S Judkins St, S Massachusetts St, S McClellan St, and Rainier Ave S.
Wheelchair access: To make our sidewalks accessible to everyone, we are adding or upgrading 30 curb ramps throughout the project area to meet the most current ADA design recommendations.
Pedestrian movements: Our analysis shows 93% of epedestrian fatalities occur on arterials. We will update pedestrian walk signals between S Judkins St and Rainier Ave S. MLK Jr Way S currently has leading pedestrian intervals (LPIs) installed from S Judkins St to S McClellan St, and we will add LPI to the intersection of MLK Jr Way S & Rainier Ave S. LPIs give pedestrians a head start when crossing, which makes them more visible to drivers who are turning.
Parking revision: There will be changes to street parking along MLK Jr Way S, including some parking removal, to support bike lane installation while maintaining access to local businesses.
New roadway paint: A fresh coat of roadway paint will improve visibility and safety conditions for pedestrians, vehicles and bicycles.

Project Area

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

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

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

Rainier Ave S and MLK Jr Way S improvements

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:
