Maine’s Airline Road 9
The straight shot across Maine's wild interior
Route 9, nicknamed The Airline for its straight-shot trajectory across Washington County, runs 90 miles of gravel and broken pavement through some of Maine’s most isolated territory. This isn’t technically 4WD, but it’s rough enough to rattle your teeth loose and remote enough that cell service disappears for 40-mile stretches. The road cuts through endless blueberry barrens – vast, rolling expanses that turn crimson in fall – before diving into deep woods where logging trucks rule the right-of-way. At Wesley, the ruins of a CCC camp mark the halfway point where crews once battled the region’s massive forest fires.
Any vehicle can handle The Airline, but high clearance helps with the washboard sections and occasional frost heaves that’ll launch a sedan airborne. Best driven May through October when the worst mud season passes, though even summer brings challenges from logging traffic that owns these roads. Fuel up in Calais or Bangor – there’s precious little between except maybe Wesley’s seasonal store. The payoff is experiencing Maine as locals know it: empty, wild, and unforgiving, where towns are 20 miles apart and the forest stretches unbroken to Canada.

Frequently asked questions
Can a stock sedan or Subaru handle Airline Road, or do I need a truck?
Most passenger cars can drive it in dry conditions, but high clearance is recommended — frost heaves, washboarding, and occasional rough patches can scrape low-slung vehicles hard. A stock Subaru, crossover, or light truck handles it comfortably year-round.
When does Airline Road typically open and close, and what's it like in mud season?
The road stays open all year, but Maine's mud season (roughly late March through April) can make sections genuinely rough, with soft shoulders and posted weight restrictions on logging trucks. May through October is the sweet spot — gravel is firm and the blueberry barrens are at their best.
Do I need a permit or are there any fees to drive Airline Road?
No permit, no fee — it's a Maine state-maintained public road. Some adjacent logging roads and private timberland may have gates or seasonal closures, so stay on the main corridor unless you've confirmed access.
What's the hardest section of the route and what should I actually expect?
Nothing on this road is technically difficult — it's a straight gravel highway, not a rock crawl. The challenge is attention: 90 miles of remote driving with no services, moose crossing constantly (especially dawn and dusk), and washboard stretches that'll rattle your gear if it's not tied down.
Where can I get gas along Airline Road, and is there any cell service?
Cell service is effectively zero for the majority of the route — download offline maps before you leave Calais. Gas up in Calais at the start or Bangor at the end; there are no reliable fuel stops along the 90-mile stretch, so leave with a full tank.
