The Expo will be held on the National Mall in Washington, DC, on Saturday, April 18, through Monday, April 20, 2009. A large tent between 3rd and 4th Streets, near the eastern end of the National Mall (close to the Capitol Building) will serve as the exhibition area for the Expo. The Expo offers a unique opportunity for significant interaction between exhibitors and students who are working to solve environmental challenges and the public who visit the Expo.
The nearest DC Metro subway stations are Archives/Navy Memorial, Judiciary Square, L'Enfant Plaza, and Federal Center SW.
