Meet Seattle Streets Alliance
Seattle Streets Alliance is the new name for Seattle Neighborhood Greenways. While our name is new, our commitment to the city remains the same: organizing neighbors to build safer streets and stronger communities.
What we work on
Street Safety
We advocate for safer speeds, better crossings, and proven safety designs so people walking, rolling, and biking can get where they’re going without fear.
Biking Connections
We work to ungap maps in Seattle’s bike and roll network so people of all ages and abilities can get to school, parks, and transit without riding in general-purpose lanes with car traffic.

We partner with communities most impacted by traffic violence and disinvestment to push for safety and access where it’s needed most.
We support street and public space designs that prioritize people over cars—welcoming places to walk, gather, and thrive.
