A proposed arch near Arlington National Cemetery is being assessed for its potential impact on historic landmarks. The National Park Service has found that the project could have adverse effects on dozens of monuments and structures in the Washington area. The proposed arch, which would stand 250 feet tall, could alter the characteristics of historic properties in the area.

This could diminish the integrity of these properties, affecting their location, design, and setting. Further details on the proposed arch and its potential impact are available from the National Park Service. The assessment highlights the potential consequences of the project on the Washington skyline.
