Why there is no J street in Washington DC

So as I was watching NCIS on the computer the other day they posed a great question and since I watched it all of the way through they told the answer at the end. But for those of you who don't watch I wanted to look up the answer myself and make sure it was really true. So this is what I found from Yahoo! searches. I am a volunteer national tour guide in Washington DC. There is no J street in Washington DC, for the simple reason that during the time period in which Pierre L'enfant was planning Washington DC, the letters I and J looked almost the same typed, and when written were indistinguishable from each other. It would just be too confusing to have two street names that looked the same, right next to each other would be too confusing. For this same reason, the army has no J company. Some tour guides will tell you that Pierre L'enfant hated John Jay and deliberately left out J street in order to slight him, however there is no historical evidence to support this. In fact, in 1994 the Washington Post printed a story which completely dispelled the John Jay myth. I found some online sources that can reinforce these facts: http://www.snopes.com/history/american/jstreet.asp http://media.www.gwhatchet.com/media/storage/paper332/news/2005/10/17/Life/Whats.The.Deal.With.No.J.Street.In.D.c-1022571.shtml
