Trump’s triumphal arch will cause a slew of ‘adverse’ effects, administration admits — but its plans are staying

The National Park Service reported that President Donald Trump's proposed 250-foot triumphal arch would have adverse effects on dozens of historical landmarks, including Arlington National Cemetery and the Lincoln Memorial corridor. The agency concluded the arch must remain at its proposed site on the Potomac River because relocation would constitute a different commemorative project, failing to meet the undertaking's purpose and need.
