quick_answer: Quick answer: Columbus does not really have two rush hours. FHWA's own study of the downtown freeway found that volume peaks around 7:00 a.m. and stays at near-peak levels until 7:00 p.m. — a twelve-hour plateau rather than a morning and an evening spike. The cause is a 1.5-mile stretch where I-70 and I-71 share a single roadway, built for 120,000 vehicles a day and now carrying up to 175,000. That stretch is 6% of Franklin County's freeway system and 27% of its I-70/I-71 crashes. The best time to leave depends on whether your route crosses it — BoardSpy checks your Columbus route and tells you when to go today.

  What is the best time to leave to avoid traffic in Columbus?,Earlier than you would elsewhere, and not at midday. FHWA's study of the downtown freeway found volume peaks around 7:00 a.m. and continues at near-peak levels until 7:00 p.m., so there is no reliable lunchtime trough on routes using the I-70/I-71 overlap. Before 6:30 a.m. or after 7:00 p.m. are the genuinely lighter windows; a midday shift buys much less here than in most cities.
  When is Columbus rush hour?,On the downtown freeway, effectively all day. FHWA documented that the system peaks around 7 a.m. and stays at near-peak volume until 7 p.m. Suburban corridors like I-270 north, SR 315 and SR 161 behave more conventionally, with inbound mornings and outbound evenings.
  What is the worst road in Columbus?,The 1.5-mile stretch of downtown freeway where I-70 and I-71 share a single roadway. It was designed for 120,000 vehicles a day and FHWA assessed it as carrying 170,000 to 175,000; the City of Columbus puts the current load at about 150,000 vehicles plus 17,000 trucks. It represents roughly 6% of Franklin County's freeway system but accounts for 27% of all crashes on I-70 and I-71 in the county, with nearly 900 crashes a year.
  Why do I-70 and I-71 run together in Columbus?,The two interstates were routed onto a shared roadway through downtown, just over 1.5 miles long, when the system was built in the late 1950s — when the city's population was about half what it is now. Because the segment carries both routes, a single incident removes two interstates simultaneously, and there is no parallel capacity to absorb the overflow. The $1.4-billion Columbus Crossroads program is rebuilding it in phases.
  What is the I-670 SmartLane?,Ohio's first active traffic-management lane. ODOT's I-670 SmartLane, which opened in October 2019 at a cost of $60 million, uses digital signs, cameras and radar to set variable speed limits and convert the left shoulder into an additional eastbound running lane when the road is congested. It operates roughly three hours a day. Average speeds on that segment were 22 mph before it was built.
  How do I find the best time to leave for my Columbus commute?,Use a leave-time commute app that reads your actual route rather than only a live map. BoardSpy recommends when to leave for your Columbus route, sends pre-departure traffic and weather alerts, and tracks on-time performance and your best and worst traffic days. Download it here.
