text: Any road mapping experts?
  Each cross-over near this point has a node connecting the ways (i.e. each left turn lane is connected to Shag. Tr. & to each other). I would interpret this to mean that each node is an intersection where a router is at liberty to route from one way to another, when this is really not the intent (could be resolved by specifying each turn allowable, but this seems inferior to simply not making the junction). Anyone know if these node should or should not be used? I can't find anything in the Wiki that is instructive.
