The following excerpt is taken from an article in Weapons and Warfare - History and Hardware of Warfare
The change in design to include a large island superstructure solved many problems posed by the flush deck design with its smoke pipes for stack gases and retractable bridge and electronic masts. The electronic suite on the new island included a large SPS-8 height finder radar atop a pedestal on the wheelhouse and a massive pole mast carrying an SPS-12 air search radar with a Tactical Air Navigation (TACAN) beacon at its top. A second large pole mast carried electronic countermeasures (ECM) antennas. These masts were both hinged so that they could be folded down (the larger center mast folded to port and rested on the flight deck while the smaller mast folded aft) for passage under the Brooklyn Bridge, which was a requirement for major naval ships at the time in order to have access to the New York Navy Yard in Brooklyn. An SPN-8 carrier-controlled approach (CCA) radar was mounted on the aft end of the island.
