The Federal Aviation Administration has finally approved the 80-story height of One Brickell City Centre, which is now set to become one of the tallest buildings in the country.

Federal officials granted the authority for developer Swire Properties to build up to a height of 1,040 feet above ground level, or 1,049 feet above sea level. After studying the proposal for 20 months, the agency decided that it wouldn’t pose a threat to air traffic.

The project is envisioned as the Brickell Avenue gateway to the under-construction Brickell City Centre complex. The new tower will include a mix of retail space, class A offices, condominiums, and a five-star hotel. A grand plaza and retail shops will be located at the ground level, connected to the first phase of Brickell City Centre by Climate Ribbon. On the top of the tower, a lounge and restaurant will be open to the public.

When completed, the tower will become the the tallest in the U.S. outside of New York or Chicago.
