What the drive from Marrero to New Orleans is like
Both ends of this route sit in Louisiana, so it is an intra-state drive with no state line to cross and one set of road rules the whole way. At roughly 11 min this is a local run rather than a trip. Traffic at either end will move the real figure more than the distance does, so time it around the peaks rather than around the mileage.
There are 5 towns of any size close to the line between the two cities, the first being Harvey, LA at about 1 miles in. That matters mostly for where you can stop: on a 11 min drive the useful question is not how far it is but where the fuel, food and daylight run out.
Driving beats flying on this one: 2 hr 19 min quicker door to door once security, boarding and the trips to and from the airports are counted. For 6 miles that is the straightforward answer.
What the fuel works out at, and what that figure assumes
6 miles at 25.4 miles per gallon is about 0.2 gallons, which comes to roughly $0.69 at $3.15 a gallon. Split between four people that is about $0.17 each, which is the comparison worth making before you look at a flight price rather than after. Two figures in that sentence are assumptions rather than facts about your trip: the price per gallon, reviewed 2026-08, and the consumption, which is a US fleet average. Both are published with the rest of the method under fuel cost assumptions.
The size of that assumption is easy to see on this route. A fifty-cent move in the pump price either way changes the total by about $0.11 — so read $0.69 as the middle of a range from roughly $0.58 to $0.80, not as a quote. A car that does noticeably better or worse than 25.4 mpg shifts it further, and neither figure includes tolls, which are charged on a good deal of the interstate network in the northeast and on individual bridges and tunnels elsewhere. Nothing on this page knows which tolls apply to a particular route, so none are counted.
For the same reason the 2 kg of CO₂ this drive implies is arithmetic on the fuel rather than a measurement: 0.2 gallons of gasoline at the EPA's figure of 8.89 kg per gallon. It is useful for comparing this route against flying it, or against a longer way round, and not useful as an absolute number.
