Cal. SHC § 30960

(a) The authority may issue both defeasance and future capital project bonds payable from the revenues of the tolls imposed on the bridges described in Section 30910. The bonds or commercial paper may be issued by the authority at any time, and from time to time, payable from the revenues from the tolls. The bonds or commercial paper shall be referred to as “toll bridge revenue bonds.”

(b) The revenues from the tolls on the bridges described in Section 30910 shall be subject to a statutory lien in favor of the bondholders to secure all amounts due on the bonds and in favor of any provider of credit enhancement for the bonds to secure all amounts due to that provider with respect to those bonds, and the lien shall immediately attach to those toll revenues and be effective, binding, and enforceable against the authority, its successors, creditors, and all others asserting rights therein, irrespective of whether those parties have notice of the lien and without the need for any physical delivery, recordation, filing, or further act, and the toll revenues shall remain subject to that lien until all bonds are paid in full or provision made therefor, and the bridges shall not become toll-free prior to that time.

(c) The liens on toll revenues created by this chapter shall be subject to expenditures for operation and maintenance of the bridges, including toll collection, unless those expenditures are otherwise provided for by statute.

(d) Interest on any bonds issued pursuant to this chapter shall at all times be free from state personal income tax and corporate income tax.
