Train
bridges have been a part of FL history since rail came into FL. Have to cross all that water in the state.
You're thinking of Henry Flagler and his Florida East Coast Railway, which connected Jacksonville to Miami with the goal of continuing to holdings in Key West, which resulted in the over-sea railroad. (In 1935, the rail link was devastated by a hurricane and the right-of-way and some of the bridges were then re-used to construct the current Overseas Highway.) Flagler convinced the state leadership he wanted to develop Key West, knowing there was the real possibility of the Panama Canal being completed soon, and he wanted to control the rail link to what he expected would be an important shipping port.
If WDI were talking about a trestle bridge over water elements, I'd be fine with that - it would look great and add visual interest. However, that's not what this particular major scenic/story element is, and that's why I point out the inaccuracy. They needed shade structure, so they came up with this very creative, historically inaccurate idea that unfortunately doesn't fit the location or larger backstory. To me, you can't do that - it violates the public trust in the story that you're trying extra hard in this case to sell. This idea is specifically modelled after the High Line in NYC, with a backstory of delivering goods to the warehouses, like the High Line did...in NYC. Not in FL. It violates the rules of the larger Disney Springs backstory, and in that case, should have been sent back for revision. You don't just greenlight an idea because it's trendy, cool or easy. First and foremost, don't violate your own story. Tell a simple, coherent story, make it believable, and don't violate your own story's inherent rules.
