Federal officials say President Donald Trump’s planned large arch would harm dozens of historic sites, but they argue the project must still move forward. The National Park Service, according to reporting, acknowledges the potential impacts on historic properties tied to the planned structure.

The outlets describe a similar assessment from federal agencies: the arch’s construction would have negative effects on historic resources. Both accounts also emphasize the officials’ position that the harm does not halt the project, indicating a process decision grounded in federal review and implementation requirements.

While both sources align on the core point—that damage to historic sites is expected—the framing differs slightly. One outlet highlights concerns about the scale of the harm to historic locations, while another emphasizes that officials still direct the construction to continue despite those warnings. Neither source, in the text provided here, details timelines, mitigation measures, or legal outcomes tied to the assessment.
