You don't drive economic growth by rebuilding infrastructure that already existed, but now in the wrong place.
You might "create jobs" that way in the general sense of stimulating an economy by borrowing against future monies, and that may be helpful in smoothing out a business cycle or avoiding a negative feedback loop, but "creating jobs" is only useful when the economy is understimulated (which it isn't at this particular moment, though I'm sure it will be again at various times between now and say 2100).
You increase the size of the economy, rather than just smooth out the business cycle, by increasing the net productivity of the population.
