Terminal 4 carries the airport’s highest volume of international arrivals and departures. Simple, clear and bold signs help multilingual visitors find their way easily through the myriad gates and amenities. The project continues a four-decade working relationship with the Port Authority of NY & NJ, comprising work at almost all of the agency's air, bus and rail complexes. Terminal 4 was planned in collaboration with Skidmore, Owings & Merrill Architects.
