One guess for why the bridges would need to be removed: the passage of whaling trawlers since the start of the industrial revolution, and we usually see them moving up and down the river. It could also be due to lack of maintenance, but then nothing was done to repair them except for Kaldwyn's Bridge which got additional defense against attacks by sea.
