A proposed arch near Arlington National Cemetery is being assessed by the National Park Service. The service found that the arch could have adverse effects on historic monuments and structures in the Washington area. The proposed arch, which would stand 250 feet tall, could alter the characteristics of nearby historic properties.

This could diminish the integrity of these properties, including their location, design, and setting. Further details on the proposed arch and its potential impact are available from the National Park Service's assessment. The service's findings suggest that the arch could affect dozens of historic landmarks across the Washington skyline.
