The Quest 4 Bread

Deciding to venture to The Supermarket you come to a freeway after miles of crawling in the sands. You must cross this freeway if you are to complete your journey to The Supermarket to obtain some bread you hear nothing and have known this freeway to be abandoned. Or so you think you wouldn't "know" considering the only news source you get is your subscription to National Geographic magazines and you live miles away. Anyway, what do you do?
