(a) Abandoned motor vehicles may be removed from the right-of-way and from private lands adjacent to Federal-aid highways for the restoration, preservation, or enhancement of scenic beauty as seen from the traveled way of the highway as a landscape or roadside development project.
(b) The State shall obtain permission or sufficient legal authority to go on private land to carry out this program. Where feasible, an agreement should be made with the owner that he will not in the future place junk, or allow junk to be placed, on his land so as to create an eyesore to the traveling public. The permission or authority and the agreement may be informal.
(c) The collection of abandoned motor vehicles from within the right-of-way must be a development project and not a maintenance operation. Once a State completes a development project for the removal of abandoned motor vehicles from within the highway right-of-way, it is obligated to continue the removal of future abandoned motor vehicles from within the development project limits without further participation.
