quick_answer: Quick answer: Denver rush hour runs roughly 7:00–9:00 a.m. and 4:30–6:30 p.m., with Fridays and snow days stretching both — and congestion here has been growing among the fastest in the country. Leaving 15–30 minutes off the peak helps, but the best time depends on your corridor and day — BoardSpy checks your Denver route and tells you when to leave today.

faqs[6]{q,a}:
  What is the best time to leave to avoid traffic in Denver?,Generally before 7:00 a.m. or after 9:00 a.m. in the morning, and outside 4:30–6:30 p.m. in the evening — and on winter Fridays, earlier still. The exact best time depends on your corridor and day.
  When is Denver rush hour?,Roughly 7:00–9:00 a.m. and 4:30–6:30 p.m., with Fridays and snow days stretching both windows significantly.
  What is the Mousetrap in Denver?,The nickname for the I-25/I-70 interchange — about 300,000 vehicles a day pass through it, rush-hour speeds average in the 30s, and it recurs on national worst-bottleneck lists. Delays there ripple onto both interstates.
  How bad is Denver traffic compared to other cities?,Denver drivers lost about 51 hours a year in the 2025 INRIX data — less than the coastal giants, but INRIX's 2024 scorecard measured Denver with the largest congestion increase in the country at 19%, so the gap is closing fast.
  Why is Denver traffic so bad?,Rapid population growth outpacing road capacity, a 30-year-old Central I-25 carrying the state's highest daily traffic, snow that rewrites the commute, and an I-70 mountain corridor that adds weekend surges no commuter grid was designed for.
  How do I find the best time to leave for my Denver commute?,Use a leave-time commute app that reads your actual route — not only a live map. BoardSpy recommends when to leave for your Denver commute route, sends pre-departure traffic and weather alerts, and tracks on-time performance and best and worst traffic days.
