For the fourth straight year, the FAA has announced a wave of funding for the upgrade, design, and building of airport control towers. The agency has again awarded $20 million in infrastructure grants as part of the Biden Administration’s Investing in America agenda, with the recipients consisting of smaller and regional airports in 15 states across the country.

“Through the Bipartisan Infrastructure Law, the Biden-Harris Administration is supporting every part of our aviation system—including airports in small communities that drive local economies and help people get where they need to go,” said Transportation Secretary Pete Buttigieg. “With today’s announcement, 20 more airports will have the resources they need to upgrade operations and make travel safer and more efficient.”

This year’s FAA Contract Tower Program grants ranged in value from $200,000 for California’s Castle Airport (KMER) to replace outdated air traffic control equipment up to $2 million for Smith Reynolds Airport (KINT) in North Carolina to rehabilitate its 1941-vintage contract tower.

While Gary/Chicago International Airport (KGYY) in Indiana has earmarked its $1.7 million grant for the replacement of its existing tower, the remaining airports will use their funds either to repair or upgrade critical systems in their current ATC facilities or to pay for the design of new towers.
