313A.21  Insurance or indemnity bond.
  When any toll bridge authorized hereunder is being built by the department it may carry or cause to be carried such an amount of insurance or indemnity bond or bonds as protection against loss or damage as it may deem proper. The department is hereby further empowered to carry such an amount of insurance to cover any accident or destruction in part or in whole to any toll bridge. All moneys collected on any indemnity bond or insurance policy as the result of any damage or injury to any such toll bridge shall be used for the purpose of repairing or rebuilding of any such toll bridge as long as there are revenue bonds against any such structure outstanding and unredeemed. The department is also empowered to carry insurance or indemnity bonds insuring against the loss of tolls or other revenues to be derived from any such toll bridge by reason of any interruption in the use of such toll bridge from any cause whatever, and the proceeds of such insurance or indemnity bonds shall be paid into the fund into which the tolls and other revenues of the bridge thus insured are required to be paid and shall be applied to the same purposes and in the same manner as other moneys in the said fund. Such insurance or indemnity bonds may be in an amount equal to the probable tolls and other revenues to be received from the operation of such toll bridge during any period of time that may be determined upon by the department and fixed in its discretion, and be paid for out of the toll revenue fund as may be specified in said proceedings. The department may provide in the proceedings authorizing the issuance of bonds for the carrying of insurance as authorized by this chapter and the purchase and carrying of insurance as authorized by this chapter shall thereupon be obligatory upon the department and be paid for out of the toll revenue fund as may be specified in said proceedings.
