The States of New Jersey and New York having, by chapter forty-three of the laws of New Jersey of one thousand nine hundred and forty-seven and chapter eight hundred two of the laws of New York of one thousand nine hundred and forty-seven, agreed that the Port of New York Authority (hereinafter called the Port Authority) should have power to acquire real property for air terminal purposes by condemnation or the right of eminent domain for the purpose of making additions, extensions and improvements to the air terminal known as Newark Airport, and other purposes incidental to said airport, but that, unless and until this State otherwise provided by law, it should not have power to acquire other real property for air terminal purposes in that manner in this State.
Now, therefore, the Port Authority is hereby authorized and empowered to acquire real property by condemnation or the right of eminent domain pursuant to and in accordance with the provisions of said chapter forty-three of the laws of New Jersey of one thousand nine hundred and forty-seven, for and in connection with the air terminal known as Teterboro Airport located in the borough of Teterboro, county of Bergen, State of New Jersey, including additions, extensions and improvements to said air terminal located in said borough and in the boroughs of Moonachie and Hasbrouck Heights or in other boroughs contiguous to the present or future boundaries of said airport, and for the purpose of acquiring air rights or preventing or removing actual or potential hazards to air navigation within three miles of the runways at said air terminal as such runways may now or hereafter exist, and for the purpose of establishing or maintaining beacons and other aids to air navigation in connection with said air terminal, whether or not within three miles of said runways; provided, however, nothing herein contained shall be construed to permit the taking by the Port Authority of any property owned by any railroad or railway corporation, or by any other corporation which is a "public utility" as defined in section 48:2-13 of the Revised Statutes, and devoted to use by such corporation in its operations, or acquired prior to the effective date of this act and held for such use, without the authority or consent of such corporation.
