I can't see the image (could you describe it in words?) so don't know how this fits in with the rest of your plans, but I'll just say that the Richardson Hwy to and through Thompson Pass/Worthington Glacier gets my vote for most beautiful road in Alaska, even better than along Turnagain Arm.
Edited to add - Oh, you said when driving FROM Valdez. How are you getting to Valdez in the first place, and are you heading to Fairbanks regardless, i.e. a big counter/anticlockwise loop from Anchorage using the ferry to Valdez?
