Is it possible to drive from continental United States to Alaska?
user
Yes, but it’s far more expensive than flying.
assistant
Why is that? Is it because I have to drive through Canada?
user
That has an impact, but the biggest cost is how much energy is required.
assistant
Right. How long is the trip if I drive?
user
It takes 12 to 14 days, if you stop and camp often.  But even that isn’t necessary, you can just drive without stopping and use motels at night, the cheapest way is to go on Highway 1 and drive all the way through California and Oregon, then go north on Highway 101 into Washington state.  At the end of Washington, you take a ferry across the Alaskan border.
