1. What is the secondary benefit?Offers aesthetic advantages due to the absence of permanent overhead structures
2. How does a submersible bridge work?When a big boat needs to cross, the bridge's central span is lowered about 8 meters below the water. Then the boat passes, and the bridge rises back up.
3. Why do submersible bridges let tall ships pass?Because the bridge goes under the water, there is no tall structure above the channel, so ships with high masts or sails can travel without hitting anything.
