Newark Liberty International Airport’s smallest and most antiquated terminal is getting a major upgrade.

A $2.7 billion project at the Port Authority of New York and New Jersey-operated facility will build a new terminal to replace 45-year-old Terminal A.

Aviation and public officials held a groundbreaking at the site Wednesday.

The terminal was designed to handle nine million passengers per year and currently sees 11 million. That’s about a quarter of the airport’s total yearly traffic.

The new terminal will feature several additional gates.

It’s expected to be fully opened by the end of 2022.

Similar large-scale redevelopment efforts are planned or underway at JFK and LaGuardia airports in New York City.
