So the main route between NY and Philly will loop through Chicago. We will build a secondary direct route between NY and philly, but it'll only allow access to certain suburbs not the entire city [1].
This route will connect NY and Chicago on its way there, and NY and philly on the way back.
I certainly don't see any advantage to any other route. not even if I were omnipotent and omniscient could I do that.

During the building of the NY-Philly-throughChicago route, we will be bringing life and jobs to the local communities, so this is of course GOOD DESIGN.

"All intrinsic laryngeal muscles except the cricothyroids are innervated by the recurrent laryngeal nerve." so I don't know what you're talking about in (1)
- JohnBerea 8y agoIf you need to make deliveries along the whole path from NY to Chicago to Philly, the path makes sense. If the road is necessary to anchor Chicago and keep it from floating away during the development of the United States, that's another reason, although our analogy is becoming strained lol. If you are missing either of the superior or recurrent laryngeal nerve, you can still speak, although not as well as if you have both. Doctors use this hoarseness as a diagnostic for various chest issues. United Airlines Flight 232 also illustrates the importance of running redundant cables through different paths. One piece of shrapnel pierced all three hydraulic systems on board, and nearly half the passengers were killed.
