Expanding service

Regional and neighborhood connections

Sound Transit's voter-approved system expansion will create a 252-mile regional network connecting communities across Pierce, King and Snohomish counties. Your tax dollars are hard at work advancing these transformative projects and services, and we want you to know how they’re going.

Ride with us

It’s easy as 1, 2, 3 – and youth now ride free 

We’ve made it easy to find everything you need to ride buses and trains. Just plan your trip and pay your fare.

Work with us

We’re working with our regional transit partners to double our hiring rate in the years ahead. That means hundreds of great-paying new operator and technician positions, and an array of exciting careers at Sound Transit. We also partner with community nonprofits through apprenticeship programs in construction trades.

Beyond transit

We aren’t just building transit

Whether you ride transit or not, we all benefit from fewer cars on our roadways, a cleaner and greener environment, more affordable housing, and equitable access to opportunities and services across our region.
