特朗普提议在华盛顿建造一座250英尺高的镀金纪念拱门，美国国家公园管理局发布报告称该项目可能破坏附近数十处历史遗迹的完整性[1]。该拱门计划位于纪念大道走廊文化景观内，坐落于林肯纪念堂和阿灵顿国家公墓之间，报告指出其建设将破坏林肯纪念堂、纪念桥和阿灵顿庄园之间的历史视线关系[1]。
该项目已获得美国艺术委员会初步批准，委员会成员均由特朗普任命[1]。国家首都区规划委员会已在7月批准了该地点和初步计划，预计将在9月再次审议[1]。然而，该项目面临来自三名退役军人和一位历史学家提起的诉讼[1]。代理律师尼古拉斯·桑松表示："在华盛顿特区中心、国家公园管理局土地上建造纪念碑需要国会的法案"[1]，诉讼人主张该项目需要获得国会批准。
A proposed 250-foot gilded commemorative arch in Washington would risk damaging the integrity of dozens of nearby historical sites, according to a report released by the National Park Service [1]. The structure would be positioned within the Memorial Avenue corridor landscape, situated between the Lincoln Memorial and Arlington National Cemetery, potentially disrupting the historic sight lines connecting these landmarks [1].
The project has already received preliminary approval from the Commission of Fine Arts, whose members were all appointed by Trump [1]. The National Capital Planning Commission approved the site and initial design plans in July, with additional review anticipated in September [1]. However, the proposal faces legal challenges from three retired military veterans and a historian who argue that constructing a monument on National Park Service land in the heart of Washington requires Congressional legislation [1]. Attorney Nicholas Samson stated that "a monument built on Park Service land in downtown Washington, D.C., needs an act of Congress" [1].
