While construction continued on the Belt Parkway system, including the Cross Island Parkway, construction was wrapping up on construction of the Bronx-Whitestone Bridge, which opened with a ceremony on April 29, 1939. Hailed as a connection to the 1939 World's Fair, LaGuardia and Moses led a ceremony of 4,000 people to watch the opening of the new $17.785 million bridge. Both politicians hailed construction of the Cross Island Parkway as the important part of the Whitestone side of the new bridge. Both the Whitestone and College Point neighborhoods had celebrations for the new project, which Moses described as a "logical and inevitable part of the Belt Parkway program".
