In May 1929, four months after Harding's death, the road was named Horace Harding Boulevard in his honor. In 1939, the New York City Council proposed renaming Horace Harding Boulevard to Worlds Fair Boulevard due to the New York World's Fair, but Mayor Fiorello La Guardia refused to remove the name of his friend. Today, it is the section between Queens Boulevard and the Queens-Nassau county line of the Long Island Expressway and is known as New York State Route 25D.
