In fact..........both buildings have 4 state avenues run right at them.........

From the White House, Sixteenth Street forms the major axis. In fact, Thomas Jefferson intended it to become the Prime Meridian, which is where Meridian Hill Park gets its name. Moving clockwise, one encounters Vermont Avenue, New York Avenue, Pennsylvania Avenue, New York Avenue, Pennsylvania Avenue, and Connecticut Avenue.

Yellow denotes sections which have disappeared.

Today, the importance of some avenues is greater than the importance of others. This is due, in large part, to their suburban connections, not any particular naming convention
