RV route guide
Alaska Highway — the US section (Tok to Anchorage)
The final leg of the 1,387-mile WWII corridor. Frost heaves, moose strikes, glaciers, and the longest border-to-Anchorage drive on earth.
The Alaska Highway runs 1,387 miles from Dawson Creek, British Columbia, to Delta Junction, Alaska, and was completed in 1942 as a wartime supply route. The US section (Alaska Highway 2 from the Yukon border to Delta Junction) is about 327 miles. From Delta Junction, the Richardson Highway continues to Fairbanks, and the Glenn Highway connects to Anchorage. For RV travelers, the corridor is paved its entire length but frost heaves, gravel breaks, and remote stretches define the experience.

Is the Alaska Highway RV-friendly?
Yes — the Alaska Highway is paved its entire length and accommodates Class A motorhomes. The challenges are not road geometry but logistics: frost heaves (sudden pavement undulations from permafrost movement), wildlife strikes (moose, caribou, bear), 200-mile gaps between fuel stations, and weather. RV travel on the Alaska Highway is genuinely demanding but does not require a special vehicle. Most RV travelers reach Alaska from the lower 48 through Canada and use the Alaska Highway as the spine.
- Paved entire length — RV-friendly
- Frost heaves cause sudden bumps
- 200-mile fuel gaps possible
- Wildlife strikes a real risk
- Best months: late May to early September

Real warnings
Frost heaves can damage rigs at speed
Sudden undulations from permafrost movement. Drive at posted advisory speeds. Slow down for marked sections.
dangerMoose strikes are catastrophic
Adult moose weighs 1,000+ lbs and stands 7 feet tall. Strike at highway speed totals the vehicle and often kills occupants. Drive cautiously dusk-dawn.
dangerFuel gaps require planning
Some sections have 150-200 miles between stations. Don't run below 1/4 tank in remote areas.
cautionCarry a satellite communicator
Garmin inReach or similar. Cell service does not exist on most of the route.

What The Milepost guidebook + Alaska tourism doesn't tell you
The Milepost guidebook is the canonical Alaska Highway reference and an excellent resource — but it is not free, it is published annually, and online tourism coverage often references it without giving travelers a complete picture. Honest framing for first-time travelers: this is a multi-week trip, not a long-weekend drive.
Tourism boards undercover the logistical reality. Frost heave repair crews work continuously through the summer. Sections that were smooth in early June can be roughened by August. Plan for slower-than-posted travel.
What also undercommunicated: the experience is genuinely worth the difficulty. The Alaska Highway is one of the great North American road-trip experiences. But it is not a trip for the underprepared.
Frequently asked questions
- How many days for the full Alaska Highway?
- From the lower 48 origin to Anchorage, plan 7-10 days minimum each way. Don't rush.
- Do I need 4WD or a special rig?
- No. Any roadworthy RV handles the highway. The constraint is preparedness, not the vehicle.
- What about Border crossings?
- ArriveCAN may apply. Carry passport, vehicle title, proof of insurance. Border services close overnight in remote crossings.
