We’re talking about infrastructure projects, which tend to be harder because they have more shared points of contention – e.g. the one rayiner mentioned was repeatedly held up by questions like whether homeowners who’d illegally fenced public land into their backyards had some right to keep it, which had to be fought up to the highest court in the state. The NIMBYs also tried things like claiming that it was uniquely endangering a rare amphipod, unlike the houses and roads they did support, etc.

WTC did not have anything like that to worry about and an exceptional level of political will to keep it on schedule.

I wonder to what extent this is due to unique features of the US political system, which most other Western countries lack. One is that local governments are much more numerous and powerful in the US, while in most other Western countries they are fewer and less powerful, with many issues dealt locally in the US instead being centralised in state/provincial or even national agencies. Another is that having a presidential rather than parliamentary system (at both the state and federal level) tends to make the executive weaker, and the legislature and executive tend to have a more disjointed/competitive rather than cooperative relationship. Yet another is a very hard two party system combined with very weak party discipline within both parties, which the existence of primaries arguably contributes to. Is it plausible that some of these distinctives could make the US a much more difficult political environment in which to successfully pull off major infrastructure projects?

WTC had a great deal of will to build something, but also a lot of political meddling because it would be so iconic. You can read up on many of the details but by the initial plan was heavily altered by many stakeholders for to add office space, security concerns, etc.

For more classic example consider say the $252 million 2.8 mile Marc Basnight Bridge which started construction July 27, 2017 scheduled to be completed on February 2019 and actually opened on February 25, 2019. While huge it was politically uninteresting compared to WTC and much cheaper, so while it ended up on time and budget nobody paid much attention.

That bridge is much closer to the typical major project in the US than the kind of things people remember because they made the news and ran wildly over budget.
