  What is the best time to leave to avoid traffic in Seattle?,Generally before 6:30 a.m. or after 9:30 a.m. in the morning, and outside 3:00–6:30 p.m. in the evening — Seattle's evening peak starts early. The exact best time depends on your corridor and day.
  When is Seattle rush hour?,Roughly 6:30–9:30 a.m. and 3:00–6:30 p.m., with I-5 and the Lake Washington bridges slow beyond the nominal windows.
  How bad is Seattle traffic compared to other cities?,Seattle sits among the ten most congested US metros in the 2025 INRIX data, with drivers losing about 68 hours a year — and congestion has been climbing as office commutes return.
  What is the worst road in Seattle?,I-5 through downtown is the signature bottleneck, with the SR-520 and I-90 floating bridges close behind — everything crossing Lake Washington funnels onto those two spans.
  Why is Seattle traffic so bad?,Geography: water on both sides squeezes the region onto one interstate and two floating bridges, so there's little spare capacity — and rain, dark winters, and rebounding tech commutes stretch the peaks.
  How do I find the best time to leave for my Seattle commute?,Use a leave-time commute app that reads your actual route — not only a live map. BoardSpy recommends when to leave for your Seattle commute route, sends pre-departure traffic and weather alerts, and tracks on-time performance and best and worst traffic days.
