Louisiana Revised Statutes Tit. 48, § 1156. Operation and maintenance

Neither the state of Louisiana, nor any subdivision thereof, the Louisiana public service commission, or any other political subdivision or agency of the state, shall interfere in any manner with the maintenance and operation of the bridge, whether as to the tolls charged for the use thereof or otherwise, except in so far as may be necessary for the public safety or to enforce compliance with the contract between the department of highways and the authority. No bridge which shall be the subject of such a contract shall be deemed to be a public utility, and no such bridge shall be subject in any manner to the jurisdiction of the Louisiana public service commission.
