- Each major road in the U.S. has an AADT, a figure representing its annual average daily traffic.
- These are the roads with the lowest AADT for each state; in other words, these are America's loneliest roads.
- The winner is the Dalton Highway in Alaska, mostly frequented by ice road truckers.
Go road-tripping across America with four-time poetry Pulitzer prize winner Robert Frost, and this is what happens: At every fork in the road, he chooses the road less traveled. And so you end up on each state’s loneliest road.
Actually, that’s not how this map came about. It owes more to bureaucratic bean-counting than to poetic obstinacy. Telematics specialists at Geotab gathered 2015 data from the U.S. federal government’s Highway Performance Monitoring System (HPMS) to find, for each state, the route with the lowest annual average daily traffic (AADT). HPMS data covers interstates, U.S. routes, and state routes over 10 miles long. That excludes Washington, DC, by the way. (The nation’s capital apparently doesn’t feature any major road of at least that length.)
Here are the top 5:
#5. South Dakota. State Route 73 (255 miles, from Lemmon, on the North Dakota state line, to Martin, on the Nebraska state line). AADT: 556.
#4. Nevada. State Route 360 (23 miles, from Dyer to Mina). AADT: 517.
#3. Montana. State Route 19 (21 miles, from Grass Range to Roy). AADT: 489.
#2. North Dakota. State Route 24 (211 miles, from Fort Yates to Solen). AADT: 242.
#1. Alaska. State Route 11 (414 miles, from Fairbanks to Deadhorse). AADT: 196.
With an AADT of 196, that means on an average day, you will be one of fewer than 200 drivers barreling down AK-11, many of them ice road truckers. For context, America’s busiest road is the I-5 stretch in the Los Angeles-Long Beach-Santa Ana metro area (*), which in 2019 had an AADT of 504,000.
With its minimal measure of motorists, Alaska State Route 11, a.k.a. the Dalton Highway, truly is the loneliest road in America — despite the claim laid to that title by U.S. Route 50 in Nevada, which also features on the list, but doesn’t even break the top 5.
Granted, with an AADT of less than 1,000, the stretch of U.S. 50 that crosses Nevada — following the old Pony Express trail across the state’s empty middle — isn’t a very busy one. But surely its traffic count has shot up since July 1986, when Life magazine proclaimed it “The Loneliest Road in America.” Yet another attraction ruined by the very tourists coming to experience it.
Lonely but pretty
Geotab asked landscape photographer James Q. Martin to pick the ten most scenic routes from America’s 50 loneliest ones. The Dalton Highway, with its sweeping views of mountain wilderness (and the occasional polar bear), again came out on top. Utah’s loneliest road got second place, with third place going to U.S. Route 201 in Maine. (For the complete ranking, check this page at Geotab).

*: and not from Los Angeles via Long Beach to Santa Ana, as previously stated. Thanks, Aaron!
**: and not the Kansas state line, as previously mentioned. Thanks to Klint Stewart for pointing this out! Incidentally, the road is shown in the wrong place on the map; it should be further west, where it can actually connect South Dakota to Colorado.
