(2) Any ferry thus acquired may be operated by the authority constructing such bridge free or on tolls, and if operated on tolls, the tolls charged shall be pledged to the payment of its revenue bonds and interest thereon issued on account of the bridge. Tolls thus collected shall be sufficient to meet all operating costs and expenses, including insurance, maintenance and a reasonable depreciation, and such payments as may have been determined by the governing authority to be necessary to apply on the amortization of the principal and interest of the revenue bonds during the period pending the completion and opening of the bridge.

(3) Upon the opening of such bridge to traffic, and thereafter while the bridge is open to traffic, no ferry thus acquired shall operate. The property used in the operation of any such ferry may be sold or disposed of by the governing authority in such manner as will protect the bridge from the competition thereof.

(4) Acquisition of any such ferry may be made upon such terms as the governing authority shall determine, and the acquisition price may be made payable not later than the time of the opening of the bridge.

(5) Whenever the governing authority of the county, city, town or port determines to proceed in accordance with this section to acquire any ferry as a part of the cost of a bridge, and to thereafter operate such ferry as permitted by this section, it may do so regardless of whether such ferry operates from a point within the boundaries of the county, city, town or port, provided that there has been received a report of engineers indicating the advisability of the acquisition of such ferry in connection with the construction and operation of the bridge.
