Trump's arch construction schedule could require '20 hours per day, year-round,' NPS report says

Published June 10, 2026 5:06 PM MST


Construction for President Donald Trump’s triumphal arch will require an intense schedule in order to be completed within the targeted three years.

The National Park Service released a preliminary assessment on what it would take to complete this massive undertaking and estimated construction would need to take place "20 hours per day, year-round." 

This will impact road closures near the construction site. 

Dig deeper:

Tower cranes up to 320 feet tall, forklifts, concrete pump systems and other equipment would be needed to build the arch.

Work would occur year-round in two 10-hour shifts per day, the Park Service report said.

The 24-page assessment by NPS staff was released last week as a part of a fast-tracked historic preservation review that began Friday.

The backstory:

Preliminary surveys and testing of the arch site began last month, and other approvals are underway. 

The U.S. Commission of Fine Arts — which only oversees designs and has no role in the actual construction or funding of the arch or any other project it considers — has approved the arch’s design.

The planned location for the arch is near the Lincoln Memorial, just across the Potomac River. 

Renderings of the arch released in April feature golden accents on the behemoth monument, as well as a winged Lady Liberty atop it.

The other side:

Critics have argued that the arch would dominate the skyline and disrupt carefully designed views between the Lincoln Memorial and Arlington National Cemetery. 

It would be more than twice as tall as the Lincoln Memorial, which is 99 feet (30 meters), and close to half the height of the Washington Monument, which is about 555 feet (169 meters).

A group of veterans and a historian have sued the Trump administration in federal court to block the project over concerns about disruptions to the sightline.

A cost estimate for the arch is still being calculated, but a mix of taxpayer and private funds is expected to pay for it.
