Nearly $1.8 billion will be used to rehabilitate and upgrade U.S. airports, Transportation Secretary Sean Duffy announced Thursday.

Duffy said the Federal Aviation Administration is awarding $1.776 billion in Airport Infrastructure Grants and Airport Improvement Program funding to modernize airports in 46 states, advancing the Trump administration's push to rebuild America's aviation system.

The grants will finance runway rehabilitation, taxiway improvements, terminal upgrades, lighting enhancements, and other safety projects aimed at improving travel for millions of Americans.

"What better way to celebrate America than investing in its future," Duffy said in a statement.

"We're ushering in the Golden Age of Transportation and rebuilding our airport infrastructure is critical to making that vision a reality.

"Under President Trump's leadership, we are building an aviation system worthy of our country's incredible history."

Among the largest awards are:

• $88.8 million for pavement projects at Denver International Airport.
• $74 million for runway rehabilitation and apron expansion at Boise Air Terminal.
• $62.4 million for runway improvements at Baltimore/Washington International Thurgood Marshall Airport.
• $62.2 million for runway construction at Houston Hobby Airport.
• $47.6 million for taxiway work and an aircraft rescue and firefighting facility at New York's John F. Kennedy International Airport.

Other major awards include:

• $36 million for terminal, taxiway, and lighting improvements at Orlando International Airport.
• $28.1 million for taxiway rehabilitation at Oakland International Airport.

FAA Administrator Bryan Bedford said the funding extends beyond basic infrastructure improvements.

"The FAA is prioritizing improving our nation's airports and ensuring we issue grants quickly and efficiently," Bedford said. "This funding does more than just rebuild runways and taxiways, it modernizes the travel experience for American families, ensuring our airports are safe and ready for the future."

The airport grants complement the Trump administration's broader effort to overhaul the nation's air traffic control system.

The DOT launched a new "Modern Skies" website allowing Americans to track more than 10,000 aviation modernization projects funded through the administration's $12.5 billion initiative, CBS News reported in May.

The online dashboard provides monthly progress updates and interactive maps showing projects across the country.

Duffy has pledged to complete major upgrades by 2028, including replacing aging copper telecommunications lines, installing 27,000 new radios, deploying hundreds of new radar systems, and upgrading air traffic control towers nationwide.

The FAA also is seeking additional funding from Congress to develop artificial intelligence tools designed to improve flight efficiency and reduce delays by predicting congestion before it occurs.

With summer travel expected to remain heavy, administration officials say the investments will strengthen airport safety, modernize critical infrastructure, and ensure America's aviation system keeps pace with growing passenger demand while reinforcing U.S. leadership in air transportation.
