Trump officials lay out aggressive timeline to build triumphal arch

Federal officials are laying more groundwork to begin construction on President Donald Trump’s planned 250-foot-tall triumphal arch, sharing additional documents that detail the project’s scope and an aggressive timetable for potentially completing work before Trump’s term ends.

According to National Park Service documents posted this month, the administration envisions 20 hours per day of construction on the arch, year-round, in hopes of completing the project within two to three years. Construction experts said that timeline — which would involve two 10-hour daily shifts — is unusually aggressive for a nonemergency project.

The arch also would be built with concrete clad in granite, unlike the nearby Lincoln Memorial and other monuments that were constructed with natural stone like marble and limestone — another way to expedite its construction, experts said.

“He’s obviously in a hurry to try to get this all done before he leaves office,” said Matthew Bell, a University of Maryland architecture professor, commenting on the timeline and materials. “Most of the major monuments in D.C. are stone.”
