How to get search paths in search engines?

Here's something interesting:

I can't paste the link. Search for "new york code" in Google. Look at the fourth and seventh entry. Neither has the URL listed, rather, they have the path structure of the breadcrumb on the page. So how did they pull this off? Each one has a static page for each breadcrumb link but I don't see it as any different as any other breadcrumb either.
