The Port Authority of New York and New Jersey was established in 1921 through an interstate compact between New York and New Jersey. The agency manages critical transportation infrastructure in the region, including bridges, tunnels, airports, seaports, and transit systems. Major facilities under the agency's purview include Newark Liberty International Airport and the George Washington Bridge. The Port Authority also operates the PATH rail system and the Port Newark-Elizabeth Marine Terminal, which ranks among the largest on the East Coast in terms of cargo volume.
