Our infrastructure problems aren't so awful. There are a few countries like Japan which really make a point of investing heavily in infrastructure as an economic strategy but it's been pretty widely seen as a failure compared to investment in social welfare through higher personal transfers and lower taxes. That's where most our spending, one way or another, goes and it's not a terrible idea. Madrid less figured out how to get oodles of money (in total there not really spending anything more than us) than how to spend their money better.
Also, it's worth pointing out, some European countries are substantially richer than us. Depends on how you count it, but in general countries like Ireland, Norway, Switzerland & Denmark have substantially higher per capita wealth and hence a greater ability to fund projects than us. They also, generally, have smaller countries which allows more concentrated investment.
