Optimal Road Trips

Chasing a world record for driving through the lower 48

The map shows a route that could give a team a shot at the record for driving through all 48 contiguous states. By my estimate, it cuts 7 hours and 10 minutes of driving compared with the route I pieced together from a 2019 team's journal.

Rebuilding the 2019 run

Road & Track reported a time of 86 hours and 19 minutes in 2021, the fastest I found. I couldn't find that team's full route, so I went back to a crew that logged 94 hours and 25 minutes in their 2019 travel journal. I connected 34 places from the journal by road and filled in likely crossings between entries.

I estimated the driving time for each stretch of road using posted speed limits where available. Then I added up those times for both routes. That's the road model behind the estimates below.

The route I pieced together came out about 4% longer than the team's reported 6,619 miles. Its estimated driving time was 15 hours and 9 minutes longer than the time they reported. Some of that difference may come from the roads I filled in and the speeds used to estimate the drive.

The new route cuts 7 hours and 10 minutes from the driving estimate even though it covers only about 39 fewer miles. Its estimate is still higher than the 86 hours and 19 minutes the 2021 team reported.

Where you cross changes the trip

Even with the states in the same order, you can get a faster route by crossing their borders at different places. I kept the 2019 team's state order and looked for faster routes through those states. Then I tried changing the order too.

Oregon was the last state on the 2019 team's list. The team wrote that the switchbacks south of Anatone slowed them down. A state counts as soon as you drive across the line, so any road into Oregon would do. My route enters on US 730 along the Columbia River.

The fastest route I found with the 2019 state order came within 3 minutes of my best result. You can visit the same states in the same order and still end up with a very different drive.

What happens on the road?

Could a team beat 86 hours and 19 minutes on this route? The pace Road & Track reported suggests the 2021 crew went over the limit on some stretches. An actual run would show how the route holds up through traffic, fuel stops, and driver changes.

The 2021 team of 3 took turns driving, navigating, and resting. For a run like this I'd also time the drive through big cities to miss rush hour and scout easy exits for fuel and driver changes. Have a navigator log each crossing so you can see where the plan held up.

Follow the state crossings

The 6,862-mile route starts in Vermont and ends in Oregon. It crosses 59 state lines and stays within the U.S.

GPX works in most navigation apps, such as OsmAnd and Organic Maps. KML opens in Google Earth. The files carry the whole route and a waypoint just inside each state.

The directions come in 16 overlapping parts. Google Maps and Apple Maps calculate their own paths between the points. Use the GPX track to see the modeled route.

The start and finish pins sit on the road. Use the South Main Street lot in White River Junction to get ready. After the Oregon line, you can continue on US 730 to Hat Rock State Park. The park requires a day-use parking permit. White River Junction parking. Hat Rock State Park.
