Yes, you can drive to Alaska, but only one way: the Alaska Highway

You can drive to Alaska from the continental United States, but there is only one road that gets you there. The Alaska Highway runs 1,387 miles from Dawson Creek, British Columbia, to Delta Junction, Alaska. It is the sole highway connection between Alaska and the lower 48 states. There is no bridge, ferry route for vehicles, or alternative road.

The drive takes roughly 20 to 24 hours of actual driving time, though most people split it across three to five days because the road is remote, services are sparse, and weather can close sections without notice. You will pass through British Columbia and Yukon Territory in Canada before entering Alaska, which means you need a passport or passport card and must meet entry requirements for both countries.

The highway is open year-round, but winter driving (October through March) is hazardous. Ice, snow, and darkness make the route dangerous, and fuel stations and lodging can be 100 miles apart. Summer is the standard season for this drive.

Key Takeaways

  • The Alaska Highway is the only road route to Alaska from the continental United States, running 1,387 miles from Dawson Creek, British Columbia, to Delta Junction, Alaska.
  • You must carry a valid passport or passport card to cross into Canada and then Alaska, and your vehicle must meet Canadian entry requirements.
  • The drive takes 20 to 24 hours of driving time but typically requires three to five days when split across multiple days, with services and fuel stations often 50 to 100 miles apart.
  • Winter driving (October through March) is dangerous due to ice, snow, and limited daylight; summer is the safest and most common season for this route.
  • Your vehicle must be in good mechanical condition, and you should carry spare tires, extra fuel, and emergency supplies because help is far away on much of the highway.

What Documents You Need to Cross the Border

A valid passport or passport card is required to enter Canada and then Alaska. A driver's license alone is not sufficient. If you are a U.S. citizen, you need either a U.S. passport book, passport card, or an Enhanced Driver's License (EDL) issued by your state. Not all states issue EDLs, so check with your state's DMV before you leave.

If you are a permanent resident or hold a different immigration status, bring your green card or travel document. Canadian border agents will ask where you are going, how long you plan to stay, and whether you have criminal history. Answer honestly and directly. Lying or omitting information can result in denial of entry.

Your vehicle registration and proof of insurance are also required at both borders. Make sure your insurance is valid in Canada — many U.S. policies cover Canada automatically, but some do not. Call your insurance company before you leave to confirm coverage extends through British Columbia and Yukon.

Vehicle Requirements and Mechanical Preparation

Your vehicle must be in safe, working condition to make this drive. The Alaska Highway has long stretches with no services, and breakdowns in remote areas can be life-threatening, especially in winter. Before you leave, have a mechanic inspect your brakes, tires, battery, alternator, cooling system, and suspension.

Carry at least two spare tires (not one), a full tool kit, jumper cables, a flashlight with extra batteries, and extra engine oil and coolant. Bring a CB radio or satellite communicator if possible — cell service is nonexistent for hundreds of miles. Fill your fuel tank whenever you see a station, even if it is not empty. Running out of fuel between stations is a real risk.

In winter, add tire chains, a sleeping bag, blankets, canned food, water, and a first aid kit to your vehicle. Many drivers also carry a small generator or power bank to keep phones charged. The Alaska Highway Traveler Information Line (1-800-550-7383) provides current road conditions and closures.

Border Crossings: Canada Entry and Alaska Entry

You will pass through two border crossings: one entering Canada at the U.S.-Canada border (usually at Blaine, Washington, or another northern crossing), and one entering Alaska at the Canada-Alaska border near the Yukon-Alaska line.

At the U.S.-Canada border, Canadian border agents will inspect your vehicle, ask standard questions about your purpose and duration of stay, and may search your vehicle. Do not bring firearms, ammunition, or prohibited items into Canada without declaring them — penalties are severe. Alcohol and tobacco have limits; check the Canada Border Services Agency website for current rules.

At the Canada-Alaska border, U.S. Customs and Border Protection will inspect you and your vehicle again. This crossing is typically less busy than the southern U.S.-Canada border, but the process is the same. Have your passport ready and be prepared to answer questions about your cargo and purpose.

Fuel, Food, and Lodging Along the Route

Services on the Alaska Highway are not frequent. Fuel stations are typically 50 to 100 miles apart, and prices increase the farther north you go. Fuel in Yukon and Alaska costs significantly more than in the lower 48 states — expect to pay 30 to 50 percent more per gallon. Budget accordingly and never let your tank drop below half full.

Lodging ranges from roadside motels to cabins to RV parks. In summer, rooms fill quickly, especially on weekends. Book ahead if possible. Towns with services include Fort St. John and Dawson Creek in British Columbia; Watson Lake, Whitehorse, and Haines Junction in Yukon; and Tok and Delta Junction in Alaska. Between these towns, options are limited.

Restaurants and grocery stores are sparse. Bring snacks, water, and non-perishable food. Some travelers pack a cooler with sandwiches and fruit to avoid relying on roadside restaurants, which can be expensive and have limited menus.

Seasonal Driving Conditions and Road Closures

Summer (June through August) is the best season for this drive. Days are long, temperatures are mild, and the road is in the best condition. However, summer also brings the most traffic, so lodging books up and fuel stations can have lines.

Fall (September) and spring (April and May) are shoulder seasons. Weather is unpredictable, and some services close for the season. Winter (October through March) is dangerous. Snow, ice, and darkness make the drive hazardous. Some sections close temporarily due to weather, and rescue services are limited. Unless you have winter driving experience and a well-equipped vehicle, avoid this season.

Check road conditions before you leave and daily while you drive. The Alaska Highway Traveler Information Line provides updates on closures, construction, and hazards. The Yukon government and Alaska Department of Transportation also post real-time condition reports online.

What Happens If Your Vehicle Breaks Down

If you break down on the Alaska Highway, stay with your vehicle. It is easier for rescuers to spot a car than a person walking. Turn on your hazard lights, stay inside the vehicle for warmth, and wait for help. Do not attempt to walk to the next town unless you are certain of the distance and have supplies.

Cell service is unreliable or absent for most of the highway. A satellite communicator or personal locator beacon (PLB) is a practical investment if you are concerned about being stranded. Some travelers also carry a CB radio to communicate with truckers, who use the highway regularly and can relay messages to authorities.

If you have roadside information through your insurance or a membership program like AAA, verify that coverage extends to Canada and Alaska before you leave. Standard towing may not reach remote areas, so ask your provider about their limits and procedures.

Frequently Asked Questions

Do I need a passport to drive to Alaska?

Yes. You must cross through Canada to reach Alaska by road, so a valid passport or passport card is required. A driver's license is not sufficient. Enhanced Driver's Licenses issued by some states are also accepted, but not all states offer them.

Can I take my pet to Alaska by car?

Yes, but you need a health certificate from a veterinarian dated within 30 days of travel. Canada and Alaska both require proof that your pet is vaccinated against rabies. Check the Alaska Department of Fish and Game website for current pet import rules before you leave.

What if the Alaska Highway is closed?

Temporary closures happen in winter due to weather. If the highway closes while you are traveling, you must wait for it to reopen or turn back. There is no alternate road to Alaska. Check the Alaska Highway Traveler Information Line before you leave and monitor conditions daily.

How much does it cost to drive to Alaska?

Costs vary based on fuel prices, lodging choices, and how many days you take. Budget roughly 1,500 to 3,000 dollars for fuel alone, depending on your vehicle's fuel economy and current gas prices. Add lodging, food, and vehicle maintenance to get a full estimate.

Can I rent a car and drive to Alaska?

Some rental companies allow one-way rentals to Alaska, but most require the car to be returned to the rental location. Rental agreements often prohibit driving the Alaska Highway or limit coverage in remote areas. Call rental companies directly to ask about their Alaska policies before you book.
