Nebraska Statutes: 16-611
16-611. Vacation of street; reversion to owners of adjacent property. Upon the vacation of any street the same so vacated shall be and remain the property of the city, but may be sold and conveyed by the city for any price that shall be agreed upon by the mayor and three-fourths of the city council. When an alley is vacated the same shall revert to the owner of the adjacent real estate one-half on each side thereof except that when any alley is taken wholly from one or more lots, upon the vacation thereof, it shall revert to the owner of the abutting property and become a part of such property. When a portion of a street or alley is vacated only on one side of the center thereof, the title of such land shall vest in the owner of the abutting property and become a part of such property.
