If land has been acquired by the state in fee simple for highway purposes, or if the state has acquired a perpetual leasehold in land for highway purposes, and if the land has not been improved subsequent to its acquisition, the state shall not sell or dispose of the land within six years of the date of its acquisition unless it first offers to reconvey it to the person or persons from whom it was acquired or their heirs or assigns, for a consideration equal to the price at which it was acquired, plus interest at the rate of six percent per year from date of acquisition by the state provided that the address of the person or persons is known to or reasonably ascertainable by the agency. The person or persons to whom the land is to be offered shall be given written notice of their right to repurchase the land under this section, and shall be allowed 60 days to complete the purchase in the event they desire to exercise that right. (Added 1985, No. 269 (Adj. Sess.), § 1.)
