Route 40 - Transit-Plus Multimodal Corridor

March 11, 2020

Making bus trips faster, more reliable, and improving safety

What's happening now?

We're postponing the Route 40 drop-in sessions (previously scheduled for March 17, 18, & 19) until later this spring.

At the City, we continue to follow guidance from our partners at Public Health - Seattle & King County (PHSKC), Washington State Department of Health (DOH), and the Centers for Disease Control and Prevention (CDC) regarding COVID-19. We're working round-the-clock to ensure our communities and our workforce can stay safe and healthy while also ensuring that projects can move forward.

We strongly value your feedback and are committed to finding ways to incorporate your input into the Route 40 corridor improvement process. We're still planning online or in-person engagement opportunities later this spring and will be in touch as soon as possible with updates about how you can be involved.

If you haven't yet, please take the Route 40 survey so we can learn about how you can get around and identify which speed and reliability improvements matter most to you. If you'd like to speak with a project team member via phone to share your feedback, please call (206) 775-8731.

Project Overview

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

Improvements made as part of the Transit-Plus Multimodal Corridor may include:

  • Reduce peak transit travel times during peak hours by 5% to 10%
  • Improve service reliability by:
    • Making the time between buses more consistent
    • Helping ensure that no matter the time of day, trips take about the same amount of time

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

With 3 million annual rides, King County Metro's Route 40 has the third-highest ridership of all their bus lines. 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.
