They are still building but none of these are at the scale China is doing. Most US projects are less than 10B, majority are around 1-2B. Meanwhile this article shows the dam China is building is over 100B.

That is why I mentioned that nothing the west is doing is that exciting, relatively. Sure, they are still large projects, but not the exciting, innovative type of "large" like Saturn V or moon landing. Just rehash and even scaled down versions of what has been achieved before.

I guess military is the only place we still see serious cutting edge advancement in US engineering. Shame that the public won't be able to benefit directly from that unlike infrastructure projects. Almost like China is taking better care of its people than the US.
