Can you say what condition the Golden Gate bridge was in before it was refurbished? Had it suffered from decades of neglect like the JSB? It might also be noted that San Francisco chose to replace the SF-Oakland bridge rather than refurbish it. To some it was almost as "iconic" as the GG. It likely came down to a matter of economics in both cases.
And there is no way that anyone will ever convince me that the JSB is in the same "iconic" league as the Golden Gate bridge, despite having the same designer. To support that argument one simply sounds foolish.
I think you missed some of the thread. SF has a bridge that is almost the same as the JSB that they preserved for heritage reasons for a not unreasonable cost.
