Paducah, KY to Hollywood, CA: distance, drive time and fuel cost

The route runs from Paducah, KY to Hollywood, CA, crossing 6 state lines — Kentucky, Missouri, Oklahoma, Texas, New Mexico, Arizona and California. Speed limits and everyday driving rules are set state by state, so what is posted can change as you cross. At roughly 30 hr 52 min of driving this is a multi-day trip for anyone driving alone. Planned as two or three stages it is a genuine road trip; attempted in one push it is a bad idea.

There are 6 towns of any size close to the line between the two cities, the first being Poplar Bluff, MO at about 119 miles in. That matters mostly for where you can stop: on a 30 hr 52 min drive the useful question is not how far it is but where the fuel, food and daylight run out.

The route also crosses a time-zone boundary, so the clock at the far end is 2 hours behind the one you set off with. Arrival times booked at the destination are in local time, which is the part people get wrong.

Flying this route saves about 25 hr door to door once airport time is counted, so the drive is a choice rather than the obvious option — worth it if you want the car at the other end, or if you would rather see the 1,944 miles than sit them out.

1,944 miles at 25.4 miles per gallon is about 76.5 gallons, which comes to roughly $241 at $3.15 a gallon. Split between four people that is about $60 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 $38 — so read $241 as the middle of a range from roughly $203 to $279, 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 680 kg of CO₂ this drive implies is arithmetic on the fuel rather than a measurement: 76.5 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.
