DC Geography Riddle - What Intersection has 2 Roads, 2 Streets and 2 Avenues?

I'll show you the location of the riddle, give you history of the landmarks and show you the updates in the area. It was pointed out to me that I mistakenly said MPD mean Maryland police department instead of correctly saying Metropolitan police department. I had to re-watch my own video to prove it to myself. LOL So please understand that I made a mistake of saying Maryland and not Metro. Thank you everybody.
