I think I paid $3.00 the last time that I went over the bridge and you pay both ways. The original bridge was made up of two separate spans, one going north and one going south. A large ship hit the original bridge and it partially collapsed sending some vehicles, including a Greyhound bus into the Bay. Originally, the bridge was actually two separate spans. The bridge goes over Tampa Bay where it empties into the Gulf of Mexico. On a sunny day, it is beautiful when on top and your cell phone connection is the best ever. They took the old bridge, you can watch them demolish it on a YouTube video, and made it into two fishing piers. You can drive out onto the piers for a fee, of course, and pay one price just to go site seeing and another price to fish off the pier. There is also a bait house on the south fishing pier and the north fishing pier as well as bathrooms. I believe the Florida Parks and Recreation division runs the piers. It has also been used for many suicides.
