Trump arch will alter sightlines of many Washington DC landmarks, report says

National Park Service, which backs the 250ft arch, says it is likely to disrupt historical significance of dozens of sites

A new National Park Service report backs Donald Trump’s proposed arch, despite what it says are adverse effects to the sightlines of a host of landmarks in Washington, including the Washington Monument and the Lincoln and Jefferson memorials.

The report released on Friday says the 250ft-tall (76-meter) memorial arch is likely to disrupt the historical significance of dozens of sites near its planned location adjacent to the Arlington Memorial Bridge.
