(a) If the Secretary determines that any part of the lands or
interests in lands owned by the United States is reasonably
necessary for the right-of-way of any highway, or as a source of
materials for the construction or maintenance of any such highway
adjacent to such lands or interests in lands, the Secretary shall
file with the Secretary of the Department supervising the
administration of such lands or interests in lands a map showing
the portion of such lands or interests in lands which it is desired
to appropriate.
(b) If within a period of four months after such filing, the
Secretary of such Department shall not have certified to the
Secretary that the proposed appropriation of such land or material
is contrary to the public interest or inconsistent with the
purposes for which such land or materials have been reserved, or
shall have agreed to the appropriation and transfer under
conditions which he deems necessary for the adequate protection and
utilization of the reserve, then such land and materials may be
appropriated and transferred to the State transportation
department, or its nominee, for such purposes and subject to the
conditions so specified.
(c) If at any time the need for any such lands or materials for
such purposes shall no longer exist, notice of the fact shall be
given by the State transportation department to the Secretary and
such lands or materials shall immediately revert to the control of
the Secretary of the Department from which they had been
appropriated.
(d) The provisions of this section shall apply only to projects
constructed on a Federal-aid system or under the provisions of
chapter 2 of this title.
