the commentary, please bear in mind that it refers to the Alaska Highway in 1978, NOT today!
The Alaska Highway starts at Dawson Creek in
mid-northern British Columbia (in Canada). This is known as "Mile 0".
The first 90 or so miles are paved, then there's about 1000 miles of gravel
road, all the way to the Alaska border, with just a few paved sections in
The entire Alaska highway is now paved (2003). Although this means
that it's a lot safer to drive, and one can get up to Yukon and Alaska a lot
faster, most of the adventure is gone. It used to be a definite journey into a
remote area of the country, along a sometimes difficult road, to reach those
northern areas. Most of that sense of adventure is now lost.
