The stretch from Terrace BC up to Watson Lake YT (the 90 degree turn right on the line) is the Cassiar Highway (37, I think). Very beautiful; don't miss Boya Lake! The side trip down to Stewart past Bear Glacier is well worth it, though I guess there is a lot less ice now than 40 years ago when the toe of the glacier was clear down to the water right across from the road.
I wonder how one would handle a fuel pump failure on the road ??? I guess start with a brand new one and hope for the best
