Route 40 - Transit-Plus Multimodal Corridor

Updated September 24, 2021

Making bus trips faster, more reliable, and improving safety.

What's happening now?

We've reached our 30% Design Milestone!

Thank you to all who participated in our spring outreach! We appreciate your input on the proposed design concepts for Route 40.

You can read the outreach summary and traffic analysis study. 

Our team has been reviewing feedback on design concepts for the neighborhoods Route 40 serves. 

Check out our 30% design concepts by neighborhood:

We recently completed a traffic analysis to study existing conditions and determine how the project improvements are likely to impact traffic flow in the project corridor.

Project Overview

Partnering with King County Metro, we plan to make improvements to this vital transit corridor. 

The objectives of the project are to reduce transit travel times, improve transit reliability, and increase safety and transit access along the Route 40 corridor. We have a goal of reducing peak transit travel times by 5% to 10% during peak hours and making the time between buses more consistent so  no matter the time of day, trips take about the same amount of time. Improvements made as part of this Transit-Plus Multimodal Corridor project will include: 

  • Dedicated bus lanes: Bus-only lanes that separate buses from traffic and improve transit travel times and reliability
  • Signal upgrades or optimization: Transit signal priority extends or activates green lights to reduce waiting times for buses at signals
  • Channelization changes or turn restrictions: Changes to roadway channelization and limiting certain turns that can allow buses to move faster, avoid conflicts, and improve safety
  • Safety improvements: Improvements to crossings and transit connections to help people get to bus stops more easily and safely
  • Sidewalk upgrades: Repaving sidewalks and upgrading ADA-accessible curb ramps in key locations 

Route 40 corridor improvements were first identified as part of the Levy to Move Seattle and King County Metro's METRO CONNECTS program. Based on results of the 2018 Levy Workplan Report, Route 40 will not be transitioned to RapidRide during this project. However, improvements will be designed to align with potential future RapidRide expansion.

Route 40 Background

Running north to south, Route 40 is 13.5 miles long and passes through the neighborhoods of Northgate, Crown Hill, Loyal Heights, Ballard, Fremont, South Lake Union, Downtown Seattle, and Pioneer Square.

Before COVID, Route 40 was one of Metro's highest ridership routes serving over 13,000 weekday riders, representing the third highest ridership route in the system behind the D and E Lines. During COVID pandemic, it remains one of Metro's top highest ridership routes, serving 3,800 weekday customers as of March 2021.

Route 40 buses are scheduled to arrive every 5 to 10 minutes during peak periods and stops are located approximately every quarter mile throughout the route. However, buses on this route are often slow and unreliable which impacts thousands of people who rely on transit. This project will identify and implement improvements that provide faster and more reliable transit service for the Route 40 and other bus routes that share the corridor.

Key Transit Connections

Route 40 connects with some of the highest ridership routes in our system, such as the RapidRide C, D, and E Lines as well as Route 44. Additionally, Route 40 terminates at the Northgate Transit Center where many regional transit routes come together. The Route 40 will connect to the Northgate and Ballard light rail stations as they are completed in late 2021 and 2027 respectively.
