I read somewhere (looking for the link now) that back when the highway system was being planned, it was felt that i95 had to go through all the major cities down the eastern seaboard, and it would be an "insult" to Philadelphia to give its highway another designation. Yes, it would have been be logical to simply redesignate the NJ Turnpike as i95 for its duration, and relabel the highway that goes through Philly with another number, but instead we got the craziness that exists till today.
