Ind. Code § 8-21-9-16
The department may acquire by appropriation, under the provisions of the eminent domain law of the state, any land, including lands under water and riparian rights, property, rights, rights-of-way, franchises, easements or other property necessary or proper for the construction or the efficient operation of any airport or airport facility. The department is empowered to exercise such powers of eminent domain as may be conferred upon the authority by an Act of Congress of the United States now in force, or which may hereafter be enacted. Title to the property condemned shall be taken in the name of the state of Indiana. Nothing herein shall authorize the department to acquire by appropriation property or facilities belonging to any public utility or to a common carrier engaged in interstate commerce, which property or facilities are required for the proper and convenient operation of such public utility or common carrier, unless provision is made for the restoration, relocation or duplication of such property or facilities elsewhere at the sole cost of the authority excepting, however, cases in which such equipment or facilities are located within the limits of existing highways or public thoroughfares.
