The Smithsonian reveals US$245m NMAAHC plans
The Smithsonian Institution has revised its plans for the creation of a US$245m (170m euro, £150m) National Museum of African American History and Culture (NMAAHC).
The amendments to the plans were introduced to secure the approval of the National Capital Planning Commission, after concerns about traffic disruption during the building process aired in September 2010.
The 315,000sq ft (29,000sq m) museum will chart the history of the black people in America.
