text: The skyway/stairs concept soon became caught up in other plans for Banneker Park. In 2004, the city proposed razing Banneker Park and building a new baseball stadium on the site. The proposal called for covering over a portion of I-395, and creating a skyway or stairs to link the stadium with the waterfront. The city's proposal also would have implemented the Urban Land Institute's 1998 proposal and created "Banneker Village Center," a project which would redevelop L'Enfant Promenade and line it with retail businesses, high-rise residences, and tourist attractions.
  However, when the stadium threatened to complicate planning for the Anacostia Waterfront Corporation, city officials withdrew their support so that the waterfront development could proceed. Even though the Banneker site had drawn the most interest from Major League Baseball, the cost of using the Banneker Park site also cost the proposal support. The stadium, named Nationals Park, was later constructed in 2007 in Southeast, Washington, D.C.
  Endangerment
  In 2004, the D.C. Preservation League listed Benjamin Banneker Park as one of the most endangered places in the District because of proposals to redevelop the park's area. The League stated that the park, "Designed by renowned landscape architect Dan Kiley ... is culturally significant as the first public space in Washington named for an African American and is usually included in Black History tours".
  In February 2005, Benjamin Banneker Park was considered as a site for the Smithsonian Institution's new National Museum of African American History and Culture. However, in January 2006, the Smithsonian chose a site on an empty block of Madison Drive NW between 14th and 15th Streets NW (west of the National Museum of American History).
