At the Seattle Department of Transportation (SDOT), we don’t just move people—we connect communities, build safer streets, and create a more sustainable city.

With a bold vision for the future, we’re tackling big challenges: making travel safer, cutting carbon emissions, and ensuring reliable, affordable transportation for everyone—no matter who they are or where they live.

Seattle is growing fast, and we’re growing with it. Thanks to a historic voter-approved $1.55 billion investment in transportation in 2024, we’re building sidewalks, fixing bridges, and improving transit connections to keep our city moving.
