Confederate Memorial (Arlington National Cemetery)
Arlington National Cemetery was established in June 1864 as a cemetery for Union (United States of America) Civil War dead. The first military burial at Arlington (a white soldier, William Henry Christman) was made on May 13, 1864, close to what is now the northeast gate in Section 27. However, formal authorization for burials was not given by Major General Montgomery C. Meigs (Quartermaster General of the United States Army) until June 15, 1864.

On March 4, 1913, Congress created the Arlington Memorial Bridge Commission (AMBC) whose purpose was to design and build a bridge somewhere in West Potomac Park which would link the city to Arlington National Cemetery. But Congress appropriated no money for the design or construction due to the onset of World War I. But after President Warren G. Harding was trapped in a three-hour traffic jam on the Highway Bridge while on his way to dedicate the Tomb of the Unknown Soldier on November 11, 1921, Harding began pushing Congress to move on constructing a new bridge. Congress approved funding for design work on June 12, 1922, and authorized construction of the Arlington Memorial Bridge on February 24, 1925.
