What does BC stand for in your post Baja California or
British Columbia ? In and en route to either of those two destinations it
is safe to assume that you must have hit some road construction ,unpaved

Going to Alaska will be no different , just an extension of

on pavement and throw in a bit of good gravel like Top of the World
Highway if the weather suits you.
