  What is the best time to leave to avoid traffic in Pittsburgh?,Generally before 7:00 a.m. or after 9:00 a.m. in the morning, and outside 4:00–6:00 p.m. in the evening. The exact best time depends on your corridor and day.
  When is Pittsburgh rush hour?,Roughly 7:00–9:00 a.m. and 4:00–6:00 p.m., per the Southwestern Pennsylvania Commission congestion-management glossary — with the Squirrel Hill and Fort Pitt tunnels slow beyond the nominal windows.
  How bad is Pittsburgh traffic compared to other cities?,In the INRIX 2025 Global Traffic Scorecard, Pittsburgh ranked 16th worst in the US at 51 hours lost per driver — up from 43 hours a year earlier, a 19% jump — at an annual cost of $939.
  Why are the Squirrel Hill and Fort Pitt tunnels so bad?,They pinch I-376 into bores with no overflow lanes. SPC treats the Squirrel Hill Tunnel as the Parkway East's main bottleneck in both directions, and PennDOT describes daily recurring congestion on the Fort Pitt / Parkway West side — so one stall or overheight truck backs up both peaks.
  Why is Pittsburgh traffic getting worse?,Demand is growing faster than tunnel capacity: INRIX measured a 19% one-year jump in delays, from 43 hours to 51, on a grid squeezed by three rivers and two I-376 tunnels that cannot widen.
  How do I find the best time to leave for my Pittsburgh commute?,Use a leave-time commute app that reads your actual route — not only a live map. BoardSpy recommends when to leave for your Pittsburgh commute route, sends pre-departure traffic and weather alerts, and tracks on-time performance and best and worst traffic days.
