Aerial view of Philadelphia, Pennsylvania, with a focus on the Benjamin Franklin Bridge, a suspension bridge across the Delaware River connecting Philadelphia and Camden, New Jersey. Owned and operated by the Delaware River Port Authority, it is one of four primary vehicular bridges between Philadelphia and southern New Jersey. The bridge was dedicated as part of the 1926 Sesquicentennial Exposition, celebrating the 150th anniversary of the signing of the United States Declaration of Independence.
