There really is no way to drive to interior Alaska, without taking the Alaska Hwy, part of the way. The Cassiar runs from Kitwanga Junction in central BC to Junction 37, 13 miles out of Watson Lake, YT. A driver can take the Alaska Hwy from Dawson Creek to Delta Junction but which ever road you take north or south, from Alaska, to Junction 37 you will be on the Alaska Hwy, even if you turn south on the Cassiar Hwy, (Hwy 37) which actually runs past Kitwanga to Kitimat BC. Or if you turn south at Haines Junction and drive to Haines Alaksa to catch the ferry, you will still be on the Alaska Hwy from HJ to Delta Junction.
