Construction of the 250-foot-high triumphal arch that President Donald Trump wants built near the Lincoln Memorial could occur 20 hours per day, year-round, as officials push to complete the project within three years, according to a preliminary assessment by the National Park Service.
Tower cranes up to 320 feet tall, forklifts, concrete pump systems and other equipment would be needed to build the arch, which would be more than twice as high as the Lincoln Memorial. Work would occur year-round in two 10-hour shifts per day, the Park Service report said.
