Tropical Park is a substantial piece of land right off of the highway and Bird Road. Forget the stadium that is there now. They would demolish and build a huge stadium in its place. I believe the reason that it is being touted as a better possibility is the size of a single piece of land (largest in the area besides killing a golf course that is unlikely). Also, the land is largely being unused, especially since Santa’s Enchanted $hithole is no longer operating, so there is more space on the periphery for parking, etc.
Also the proximity to a major highway is important for traffic control (could you imagine FLA Live - former BB&T Center without a highway next too it; it would be gridlock before and after games or shows). On the same note, which stadium in the area doesn’t have a major highway next to it (Hardrock - turnpike, Marlins - 836, FLA Live - Sawgrass and 595, FTX - 95 and downtown is a mess with Heat games until traffic clears). So putting a stadium on the corner of Le Jeune and US1 would be a nightmare since you can’t go through the gables since it would create a mess and you have 7 miles of traffic on US1 from the end of 95 that is already undesirable. The only thing redeeming about this is that it doesn’t have water on one side of it so you have 4 directions to leave from it instead of 3.
I live close to the stadium in Broward so I love it there. But if it had to be somewhere, the only way that you make it possible is Tropical Stadium due to ability to control traffic experience. Canes fans have been displaced all over South Florida beginning with Hurricane Andrew and you need to cater to all so that you don’t end up with a smaller empty stadium because it is too difficult to get into and out of.
