Construction of the tallest building in the United States has been halted.

The construction of the Legends Tower, which stands at 581 meters and has been approved by the Oklahoma City Council, has been postponed due to a letter from the local airport director, Jeff Mulder. The official submitted a request to the Federal Aviation Administration regarding concerns that the new skyscraper could jeopardize flight safety.

It remains to be seen whether this request will lead to a complete halt of the project or if some form of compromise or redesign will be necessary. For now, construction has been delayed until 2025.
