1600 Pennsylvania Avenue

Pennsylvania Ave. between 15th St. NW and 17th St. NW, Washington, D.C.


This stretch of Pennsylvania Avenue was established in 1804 when President Jefferson ordered a grand avenue to be cut through President’s Park. It remained a city thoroughfare for almost two centuries. In most recent history, motorists could catch a drive-by glimpse of the White House. Security concerns forced the avenue to be temporarily closed to vehicles in 1995. In 2004, it was transformed into an inviting and flexible public space for pedestrians, as well as formal and informal events unique to the nation’s capital.
