Frequently Asked Questions

When is the next 550 bus?
The arrival boards on this page show live 550 arrival times at key stops along the route, updated every 60 seconds. The data comes from real-time GPS tracking by Sound Transit, not the static published schedule. If a bus is delayed or running ahead, the times here reflect its actual position on the route.
How often does the 550 run?
Buses run every 10-15 minutes during peak hours, every 15-30 minutes off-peak, and every 30 minutes on weekends. Service starts around 5:00 AM and runs until approximately midnight, with reduced weekend service. Actual intervals can vary due to traffic or service disruptions, which is why the live arrival times on this page are more useful than the published timetable for planning your trip.
How many stops does the 550 have?
The 550 serves 28 stops, running from Pike St & Convention Pl to NE 4th St & 108th Ave NE. Each stop has its own dedicated page on this site with live arrival data, a map, and nearby stops — so you can find real-time info for wherever you board.
What is the 550 schedule on weekends?
Weekend service on the 550 typically runs at reduced frequency compared to weekdays. Buses run every 10-15 minutes during peak hours, every 15-30 minutes off-peak, and every 30 minutes on weekends. Because weekend schedules can shift, the live arrival times on this page are the most reliable way to see when the next bus is actually coming.
How accurate are the arrival times on this page?
The arrival times are based on real-time tracking from Sound Transit, not a static timetable. When buses are running behind schedule or ahead of it, the times here update to reflect the vehicle's actual position. A green dot next to a time means it's a live-tracked prediction; a gray dot means the system is using the published schedule for that trip.
Can I see 550 arrivals without my phone?
Yes — NextStop Mini is a small, always-on countertop display that shows live 550 arrival times at any stop you choose. It connects to your Wi-Fi and updates automatically throughout the day. No app to open, no phone to unlock — just glance at it on your way out the door. Setup takes under two minutes.
