Deletion of Interchanges in Pennsylvania

Comment: An awful amount of original research and self-published sources (of what few sources exist) in the article but the general consensus per  is that highway interchanges aren't inherently notable  and generally (bar a few exceptions in the notability policy) should be mentioned only in the respective highway article. Also per nom that no similar article exists for other US states
