Trump arch could take up to three years and 20 hours of construction per day

One of President Donald Trump’s pet projects to mark the 250th anniversary of American independence is set to be built on a vigorously demanding construction schedule.

The soaring triumphal arch, designed to sit between the Lincoln Memorial and Arlington National Cemetery, would require a 20-hour-a-day work schedule over two to three years, according to National Park Service documents published in the Federal Register. Plans for the monument indicate it will be a five-level structure, with an observation deck and a mezzanine level that could contain exhibit space, restrooms, a café, and a gift shop.
