The U.S.A. also went through rapid de-industrialization for the last 30 years. Look at what is called the 'rust belt' in the North-East. Does the U.S.A., need all the bridges and roads it once built. Detroit is contracting.

Some towns might even be better off economically if they removed all their old bridges and replaced access to a town with a small ferry. If a town has transformed into a retirement community, becoming more bucolic and scenic would attract retirees and tourists. It would be less of a burden with up keep, more of a tourist draw.
