The proposed arch -- which at 250 feet (76.2 meters) would be the largest structure of its kind in the world -- is one of several construction projects the US president is pushing to put his personal stamp on Washington.

The Kennedy family said in documents filed Tuesday that the arch would block views of the former president and his relatives' gravesites, "destroying an essential element of the gravesites' design."
