        313A.22  TOLL CHARGES FIXED BY DEPARTMENT.
         The department is hereby empowered to fix the rates of toll and
      other charges for all interstate bridges acquired, purchased, or
      constructed under the terms of this chapter.  Toll charges so fixed
      may be changed from time to time as conditions may warrant.  The
      department in establishing toll charges shall give due consideration
      to the amount required annually to pay the principal of and interest
      on bonds payable from the revenues thereof.  The tolls and charges
      shall be at all times fixed at rates sufficient to pay the bonds and
      interest as they mature, together with the creation and maintenance
      of bond reserve funds and other funds as established in the
      proceedings authorizing the issuance of the bonds, for any particular
      toll bridge.  The amounts required to pay the principal of and
      interest on bonds shall constitute a charge and lien on all such
      tolls and other revenues and interest thereon and sinking funds
      created therefrom received from the use and operation of said toll
      bridge, and the department is hereby authorized to pledge a
      sufficient amount of said tolls and revenues for the payment of bonds
      issued under the provisions of this chapter and interest thereon and
      to create and maintain a reserve therefor.  Such tolls and revenues,
      together with the interest earned thereon, shall constitute a trust
      fund for the security and payment of such bonds and shall not be used
      or pledged for any other purpose as long as such bonds or any of them
      are outstanding and unpaid.
