Many countries in the Anglosphere (US, UK, Australia) seem to have lost their ability to pull off big infrastructure projects.

I don't think London could build their sewers today either, nor their tube system. https://en.wikipedia.org/wiki/London_sewerage_system#History

I'm glad to be living in Singapore where that kind of building capacity is still alive. They are currently building multiple new underground train lines. Driverless, of course.
