Nov 10 (Reuters) - Several members of the Kennedy family, one of America's most famous political dynasties, filed on Tuesday to join a court case aimed at stopping President Donald Trump from building a proposed triumphal arch in Washington, saying it would obstruct views and cast shadows over their relatives' grave sites.
The 250-foot (76-meter) arch, shown in a rendering to include a flame held by a 60-foot gold winged female figure and flanked by gold flying eagles, would be situated
across the Potomac River from the Lincoln Memorial on a highway roundabout near the entrance to the Arlington National Cemetery.
A judge has already issued a temporary order blocking construction through November 19 as she considers whether to issue a preliminary injunction.
The arch "will permanently cast shadows over and damage historically significant sight lines to the existing grave sites and memorials established in the Kennedy family’s honor at Arlington National Cemetery, as well as to the memorials of hundreds of thousands of fallen American heroes," the filing said.
The Kennedy family is one of the most prolific political dynasties in US history, notably including former President John F. Kennedy. Trump's health secretary is Robert F. Kennedy Jr., nephew to the assassinated former president.
The White House did not immediately respond to a request for comment from Reuters.
The Trump administration contends Congress approved the arch more than 100 years ago when it also authorized construction of a bridge across the Potomac River. It has said that the arch would honor veterans.
Numerous Democrats in Congress have vowed to block construction once they take control in January, after winning November's midterm elections.
