New York City-area business aviation hub Teterboro Airport (KTEB) formally opened its new control tower this week, with a dedication ceremony by the FAA.

The 157-foot-tall tower, built at a cost of $73 million, became operational in late October. It more than doubled the height of the previous tower, which was commissioned nearly 50 years ago.

It features a 750-sq-ft cab providing a panoramic view of the bustling airfield—the busiest general aviation airport in the U.S.—and sits atop a 19,000-sq-ft building that houses offices for controllers, technicians, and administrative staff. It will be home to 41 FAA employees including 29 air traffic controllers and 12 technical operations personnel.

The tower’s design meets the Guiding Principles for High Performance Sustainable Federal Buildings code with reduced water use, resource conservation, waste reduction, and indoor air quality protection, among other criteria. Equipped with the latest ATC equipment, the facility was planned to meet current and future demand.

“Aviation is an invaluable part of everyday life and our national economy, which is why we need the right infrastructure at our airports,” said outgoing FAA deputy administrator Katie Thomson. “This taller and more modern control tower will not just make it easier for controllers to keep the National Airspace safe, but it will help the airport expand its flight operations. That means more options for consumers and businesses alike.”
