Seattle Streets Alliance
Seattle has made meaningful progress expanding its bike network over the past decade, helping more people choose biking as a safe, affordable, and climate-friendly way to get around. But today’s network remains incomplete. Too many bike lanes begin and end abruptly, forcing riders into dangerous conditions at intersections, along busy streets, or through neighborhoods without safe connections.
We envision a citywide network of safe, comfortable bike routes that work as a true system — one that connects people to schools, jobs, parks, transit, and everyday destinations in every neighborhood. A connected network means biking is not just for the confident few, but a practical and welcoming option for people of all ages and abilities.
Building this network isn’t only about adding new miles of bike lanes; it’s about closing critical gaps, strengthening connections, and ensuring routes are intuitive, well-maintained, and easy to navigate. When the network works as a whole, biking becomes safer, more predictable, and accessible for everyone.
After celebrating important new routes in 2025, our work now focuses on community-driven efforts to close the gaps that matter most.
What Streets Alliance Is Doing
After celebrating several long-awaited route openings in 2025, our work is now focused on neighborhood-led campaigns to connect the network Seattle already has — turning disconnected segments into a system that works for everyday trips.
Major connector routes
Advancing key corridors that link neighborhoods and complete missing pieces of the network, including Beacon Ave S, N 130th St, S Henderson St, E Marginal Way, Fauntleroy Way SW, and Eastlake Ave E.
Small gaps with big impact
Addressing short but critical missing links — especially in the Duwamish Valley and Chinatown–International District — alongside policy changes that prioritize building complete networks instead of isolated projects.
Bike policy and wayfinding
Ensuring routes are easy to follow, clearly signed, well-maintained, and welcoming for riders of all ages and abilities so people can confidently navigate across the city.
