World's largest road map

My favorite Steven Wright joke: "I have a map of the United States--actual size." But what really is the largest road map? It's 130 by 166 feet... created for the 1964 World's Fair. Sadly it's fallen into disrepair although I did see it featured in an episode of CSI New York not long ago. You can read more about it here... or here.... and efforts to restore it here.
