Plus, if you ask what the next phase is in this massive, four-year project, the official answer is “TBD” — to be determined.

The construction project — officially a long overdue upgrade of White House utilities — began in September 2010 with the excavation of a huge, multistory pit in front of the West Wing, wrapping around to include West Executive Avenue, the street that separates the White House from the Eisenhower Executive Office Building. A tall, green construction fence sprang up that blocked America’s most famous office complex from public view.

But now the fence has come down, revealing the familiar whitewashed sandstone facade and the lone Marine guard who stands watch at the entrance to the West Wing lobby.
