This is summer time and I have always wanted to go north and see the
land of the midnight sun. With global warming it should not be too
cold either.
So, I want to drive as far north as possible. I live in the 48
contiguous states of the USA. I need to know what proper roads to take
to go as far north as possible. And food, lodging, gas along the way.

Hello andromedanebula-ga:

It is a pleasure to answer your question. A road trip to the Arctic
Circle shouldn?t be a problem these days as there are accessible roads
in the summer time. Before I continue, it is interesting to know that
there are only two highways in North America that cross the Arctic
Circle. One is the famous Dalton highway that runs from Fairbanks,
Alaska to the northern most point in Alaska at Prudhoe Bay. The Arctic
Circle starts even before the half way point. The other is the
Dempster Highway in the North West Territories of Canada. It starts 25
miles north of Dawson City (Yukon) and ends up at Inuvik (NWT). The
Arctic Circle starts at the half way point.

Both of these highways are accessible in summer. You will find these
highways listed in all of the major map guides as these are major
routes. The Dempster Highway in Canada is also known as the routes 5
and 8. I will not go in detail on the routes that you should take
because it is up to you to select the best and most desirable route to
these major highways.

Here are the details of what you should prepare for, if you undertake
a journey on these routes:

I hope this will help you in planning a safe trip. If you have further
questions, I will be more than happy to assist you. Also, if you think
that my answer is incomplete, please let me know.
