Overview
- New National Park Service documents describe an aggressive construction schedule of two 10-hour shifts per day, year-round, aiming to finish the 250-foot arch in two to three years.
- The Federal Aviation Administration has opened an aeronautical study because the site sits under Reagan National Airport flight paths and the arch would exceed 200 feet.
- Preliminary site surveys and geotechnical testing have begun as Park Service teams consider large cranes and deep foundations on river-adjacent soils that pose engineering challenges.
- The U.S. Commission of Fine Arts gave advisory approval to a revised design but advisory sign-off does not authorize construction and no congressional approval or dedicated funding has been secured.
- Veterans and an architectural historian have filed suit to protect memorial sightlines, and court rulings, FAA findings or funding gaps are now the key factors that could stop or reshape the plan.
