Dupont Circle

Dupont Circle in Washington has 10 streets that intersect. This was part of L'Enfant's original design, although then it was called Pacific Circle. "The neighborhood is centered around the traffic circle, which is divided between two counterclockwise roads. The outer road serves all the intersecting streets, while access to the inner road is limited to through traffic on Massachusetts Avenue. Connecticut Avenue passes under the circle via a tunnel; vehicles on Connecticut Avenue can access the circle via service roads that branch from Connecticut near N Street and R Street.  The park within the circle is a gathering place for those wishing to play chess on the permanent stone chessboards."

Brilliant!
