There is a good reason for not having precise boundaries, they are VFR routes and there is no means to determine the position from the center of the route with a good accuracy, it is just visual navigation. And at night.
Errr. No means to identify the East bank of a major river in the middle of a well lit city at night ? Not sure about that. They are what they are though and I'm sure Jennifer would have checked her facts. Just by way of comparison, I can assure you if you were 1000ft away from the London Heliroutes over Heathrow you'd have the undivided attention of the controller.
