quick_answer: Quick answer: The Greater New Orleans Expressway Commission puts the weekday peaks at 6:00–9:00 a.m. and 3:30–6:30 p.m. The commute here is shaped by water, not volume. The Lake Pontchartrain Causeway is 24 miles of open water — Guinness's longest continuous bridge over water — carrying about 40,000 vehicles a day, and until a recent safety project the only places to stop were crossovers about four miles apart. Twelve pull-off bays have since been added: twelve stopping places across twenty-four miles. And when fog settles, a police vehicle leads every car across in convoy. BoardSpy checks your New Orleans route and tells you when to go today.

  What is the best time to leave to avoid traffic in New Orleans?,Before 6:00 a.m. or after 9:00 a.m. in the morning, and outside 3:30–6:30 p.m. in the evening — the windows the Greater New Orleans Expressway Commission publishes for weekday commuting. Neither LADOTD nor the Regional Planning Commission publishes a rush-hour definition, so the Commission's figures are the official ones available. If your route crosses the Causeway, fog matters more than the hour.
  When is New Orleans rush hour?,The Greater New Orleans Expressway Commission states that most traffic falls between 6:00 a.m. and 9:00 a.m. and between 3:30 p.m. and 6:30 p.m. on weekdays. The Causeway's own fog procedures identify the peak travel direction as southbound in the morning and northbound in the evening.
  How long is the Lake Pontchartrain Causeway and what does it cost?,It is 24 miles long — 38.422 km, or 23.87 miles, by the Guinness World Record measurement for the longest continuous bridge over water, a record it has held since 1969. The toll is $3.40 with a toll tag or $6.00 cash, collected southbound only. Northbound collection was eliminated in 1999 to ease congestion on the south shore, so you pay to come into the city and nothing to leave.
  What happens on the Causeway in fog?,The Commission operates two published restriction phases. Under single-lane restrictions, cones close the left lane, all traffic uses the right and passing is prohibited. Under rolling convoy restrictions, both lanes stay open but an emergency vehicle leads from the toll plaza setting the pace, with no passing and no lane changes. A ranking police officer decides when to implement them, and the Commission does not publish the visibility thresholds that trigger either phase.
  How many bridges cross the Mississippi in New Orleans?,Four in the metro area: the Gramercy Bridge, the Hale Boggs Memorial Bridge carrying I-310, the Huey P. Long Bridge carrying US-90, and the Crescent City Connection carrying US-90 Business. Below the Crescent City Connection there are no bridges at all — only ferries — making it the last bridge on the Mississippi River. Three bridges cross Lake Pontchartrain: the Causeway, the I-10 Twin Span and the US-11 Maestri Bridge.
  How do I find the best time to leave for my New Orleans commute?,Use a leave-time commute app that reads your actual route rather than only a live map.
