An aircraft without DME, LORAN, and GPS may wish to stay out of the
Boston Class Bravo airspace. An excellent way to do that is follow
495 around Boston. For those that want the torture, I know it can be
done with just one VOR.

I see that the 495 is almost north-south (magnetic) in some portions.
How do you manage your altitude when flying that portion of the
highway?

A more difficult situation arises when the highway meanders
substantially back and forth from east to west, constantly crossing
360 or 180 degrees. If it's in hilly country (as it might well be if
it has to meander back and forth), just setting a single heading might
not be an option, as you can easily lose sight of the highway. So, in
that case, how does one manage altitude?
