A site that I visit frequently used to be located at:

    http://www.site.com/sub/dir

But now it's just located it:

    http://www.site.com/sub

The problem is, I visited the original location so often that Safari suggests it as the Top Hit and autocompletes it, even though it no longer exists (it returns a `404`). So I start typing `http://www.site.com/fol...` and Safari fills in the rest with the old URL that no longer works.

How can I remove the old URL so Safari no longer autocompletes it? I already went and found the URL in my history and deleted it, but it still suggests it as the Top Hit.
