In Europe such discussions are daily occurrence. I.e. in Prague is a 100 years old riveted railroad bridge. After extensive usage for a century rivets holes are fatigue ripped apart and bridge was slowly becoming useless. There were two solutions 1. Reconstruction and refurbishment of the bridge, where look and capacity would remain same. However it would require another reconstruction in few decades in perpetuity because structure is essentially broken and reconstructions would be jut keeping the bridge on living support for a little bit longer. Historical conservatives were very much in favor of that one 2. Ripping old bridge apart (except pylons) and building a new one for same amount of money as solution 1) and without a need of perpetual reconstruction, just regular maintenance. Luckily this solution has won. https://english.radio.cz/rail-bridge-connecting-vyton-and-smichov-receive-huge-overhaul-8768036 https://english.radio.cz/rail-bridge-connecting-vyton-and-sm...
