NEWARK, N.J. (WCBS 880) -- We’ve already heard about improvements planned for John F. Kennedy International and LaGuardia airports, and now plans have been outlined for a new terminal at Newark Liberty International Airport.

A ceremonial groundbreaking was held at the airport on Wednesday, and WCBS 880’s Peter Haskell was there.

With its drab, dated décor and small bathrooms, even Port Authority of New York and New Jersey Chairman Kevin O’Toole admits the existing terminal is a dump.

"It is almost uninhabitable right now," O’Toole said.

The new Terminal 1 will be about 20 percent larger with 33 gates. Port Authority Executive Director Rick Cotton thinks the difference will be night and day.

"The new terminal is going to be state of the art,” Cotton said. “It's going to have the best possible security. It's going to have improved passenger amenities and all of the efficiencies that airports have adopted."

They are also adding 140 acres on the air side.

"There will be taxiway improvements also to improve the movement of planes,” Cotton said. “It is all designed to develop a much more efficient passenger-friendly operation."
