Excavation work for the construction of President Donald Trump’s proposed 250-foot “triumphal arch” will begin over the next two weeks, Interior Secretary Doug Burgum announced.

“We are pleased to announce that after a very long wait (over 125 years!), we are preparing to start, over the next two-week period, the excavation work necessary for the Great Triumphal Arch and Military Observation Deck, at Memorial Circle on Columbia Island between the Lincoln Memorial and Arlington National Cemetery,” Burgum wrote in a social media post on Thursday.
