JERSEY CITY - The Port Authority of New York and New Jersey has announced a new command structure for its nearly 1,600 police department.

The reorganization announced Tuesday in Jersey City follows the appointment of the agency's first chief security officer, Joseph Dunne.

Dunne announced the promotion of 54 officers within the force and the appointment of 10 officers hired from police departments in the region. The agency says additional supervisors will allow the department to respond quickly to changing needs and save money.

The promotions include the first women to become assistant chiefs in the department's history.

Assistant Chief Gloria Frank of Patchogue, N.Y., was the commanding officer at the World Trade Center site. Assistant Chief Norma Hardy of Neptune, N.J., was honored for courage during the 1993 World Trade Center bombing.
