It's quite possible. And that shape does solve the major issue of scaling facilities like that, since the port space would only expand linearly with size, relative to the increase in perimeter at arbitrary distance. Throughput would have to be absurd, though, to move enough cargo to support a facility of that size. I suspect that there'd be a massive freight rail hub on shore.
