11 months is truly impressive but of course a far cry from a single month. A bridge also needs no machinery and workers permanently dedicated to it. IMO it's absolutely crucial for the US to cut down red tape and silly regulations to allow all construction to get done much more rapidly. I also wonder how this translates to building many projects like it at the same time. I understand construction capacity and backlogs are a huge bottleneck and we are in the process of deporting large numbers of people who could work on it while never having been good at growing a strong workforce in trades that require certification like electricians because we won't give out H1Bs for those.
