New Jersey Statutes Title 27. Highways 27 § 7-22.6

In addition to the powers now vested in the Commissioner of Transportation for the acquisition of lands or rights therein by virtue of any statute, the commissioner may, in his discretion, acquire by gift, devise, purchase or condemnation, an entire lot, block or tract of land, if, by so doing, the interests of the public will be best served even though said entire lot, block or tract is not needed for the right-of-way proper but only if the portion outside the normal right-of-way is landlocked or is so situated that the cost of acquisition to the State will be practically equivalent to the total value of the whole parcel of land; provided, however, that the commissioner shall not have the power to acquire by the exercise of the right of eminent domain for any of the purposes of this act any property or property rights owned or used by any public utility as defined in section 48:2-13 of the Revised Statutes.
