Well, the bridge is designed in a way that allows it to be easily and safely dismantled.
The 2017 government promised to not dismantle it anymore, but 2022 government seems to disagree. The important part we're missing are the risk assessments from engineers involved in the project.
As far as I understand from reading the news, the 2017 promise was mostly given because at that time the local government had left the bridge covered in scaffolding for an excessively long time.
Apparently the bridge was redesigned and to be brought back in its old state (its a monument) was also made to be deconstructed. The previous version of the bridge was able to let ships through. Or so I heard.
Not all people are wealth maniacs.
