John F. Kennedy International Airport’s Terminal 8 will undergo a $344 million overhaul as part of a $13 billion redevelopment of New York City’s main international gateway.

The plans, announced Wednesday, solve a piece of a complex puzzle in which the Port Authority of New York and New Jersey, which runs the airport, seeks to redevelop the busy hub while keeping it in operation.

The airport served a record 61 million passengers in 2018, up 2.5% from the previous year, according to the Port Authority.

“Today, we are seeing the JFK transformation project is well under way, with an extraordinary private investment that will turn JFK into a truly modern airport,” said New York Gov Andrew Cuomo.

The overall airport modernization was unveiled last fall by Port Authority Executive Director Rick Cotton. The vision for the new airport includes new taxiways and roadways as well as additional gates and vast, new light-filled terminals.
