Neb. Rev. Stat. §§ 14-1249
Whenever the electors of any city of the metropolitan class have authorized the construction of a bridge as provided in section 14-1201, the city council shall have the power to construct such bridge independently or jointly with any state or political unit as authorized in section 14-1202. Such cities are authorized to enter into any contract which may be necessary to effectuate this purpose. The title to all property thus acquired shall vest in the political units cooperating as tenants in common. The actual control of all construction and subsequent operation, including all property necessary to the bridge, all maintenance and repair of such bridge, and all funds and the collection and custody of tolls, shall vest in a joint bridge commission as provided in section 14-1244. Such joint bridge commission and its control shall not be terminated until such tenancy in common is terminated.
