(1) In the case of a county highway, before it is disposed of in any way, it shall be first offered to the abutters for a reasonable length of time and at a reasonable price, and if they do not take the county highway, then it may be sold at public auction; and

(2) If any county highway, the right-of-way for which has been acquired in whole or in part by expenditure of federal funds, is abandoned and disposed of, the necessary portion of the proceeds from the sale thereof shall be remitted to the State for reimbursement or credit to the Federal Highway Administration, if reimbursement or credit is so required.
