The entire area is horribly mapped.  A randomly selected road hasn't been touched since the TIGER import which leaves a lot to be desired.
Luckily there is some halfway-decent-yet-poor leaf-off satellite imagery available as ESRI (or Bing), and probably the older Bing aerials from other providers, which can be used to at least straighten the ways and sorta align them to reality.
There is, sadly, no excellent and well-orthorectified detailed aerials to clarify the many questions to raise themselves as I study the imageries to ask, do I even want to get started, knowing I'll soon give up?
We shall see.
