The highway department of the State in which such dam shall be located, jointly with the Secretary, shall first determine and certify to such agency that such bridge is economically desirable and needed as a link in the State or Federal-aid highway systems, and shall request such agency to design and construct such dam so that it will serve as a suitable and adequate foundation for a public highway bridge and to design and construct such public highway bridge upon and across such dam, and shall a ^ e e to reimburse such agency pursuant to subsection (d) of this section for any additional costs which it may be required to incur because of the design and construction of such dam so that it will serve as a foundation for a public highway bridge and for expenditures which it may find it necessary to make in designing and constructing such public highway bridge upon and across such dam. In no case shall the design and construction of a bridge upon and across such dam be undertaken hereunder except by the agency having jurisdiction over and custody of the dam, acting directly or through contractors employed by it, and after such agency shall determine that it will be structually feasible and will not interfere with the proper functioning and operation of the dam. (b) Construction of any bridge upon and across any dam pursuant <:o this section shall not be commenced unless and until the State in such State, shall enter into an agreement with such agency and with which such bridge is to be located, or the appropriate subdivision of the Secretary to construct, or cause to be constructed, with or without the aid of Federal funds, the approach roads necessary to connect such bridge with existing public highways and to maintain, or cause to be maintained, such approach roads from and after their completion. Such agreement may also provide for the design and construction of such bridge upon and across the dam by such agency of the United States and for reimbursing such agency the costs incurred by it in the design and construction of the bridge as provided in subsection (d) of this section. Any such agency is hereby authorized to convey to the State, or to the appropriate subdivision thereof, without costs, such easements and rights-of-way in its custody or over lands of the United States in its custody and control as may be necessary, convenient, or proper for the location, construction, and maintenance of the a])]iroach roads referred to in this section including such roadside parks or recreational areas of limited size as may be deemed necessary for the accommodation of the traveling public. Any bridge constructed pursuant to this section upon and across a dam in the custody and jurisdiction of any agency of the United States, including such portion thereof, if any, as may extend beyond the physical limits of the dam, shall constitute and remain a part of said dam and be maintained by the agency. Any such agency may enter into any such contracts and agreements with the State or its subdivisions respecting public use of any bridge so located and constructed as may be deemed appropriate.
