There are alot of different area's to fish around the spit bridge area. You can fish under the bridge on both sides and this can produce catches of Bream near the pylons. Live baiting with Squid, Yellowtail or Mullet in the deep channel can produce Jew and King fish for the lucky ones who are willing to put in the time and effort, and Tailor can be taken in the channel as well. Other species can also come out of this area including Flathead and pike. Fishing around from the marina in the bay on the southern side of the bridge can produce good catches of Bream in around the boats and moorings, Flathead are also good catches from this area. Burleying up with bread can attract Garfish that can be caught with the aid of a float, or with bread files on a fly rod. Further around the bay a bit further on the rocks you might be able to find Leatherjacket, Flathead and Bream. On the other side of the bridge you can find some area from the rocks to fish, and further around there is a large area of sand flats where you could wade and try for Flathead, Whiting, and Bream on hardbody and soft plastic lures or flies.
