Whenever the director finds that it will facilitate travel and promote public convenience or that it will avoid the need for additional road building, the director may procure rights of way and other interests in land adjacent to established public highways for the location of custom and immigration buildings to be erected by the federal government. The director is hereby vested with like power in the acquisition of such lands as the director may have in acquiring rights of way and land for highway purposes.
