You can hold down CTRL and drag a box and anything intersecting that
box will be selected. But that won't really help you in this case
either... I guess you just have to zoom in really far. Then it becomes
obvious that there are two ways.

I wonder if he had problems downloading data from the API. It's like
he got Conant Road downloaded, maybe when he was panned to the west a
little. Then maybe he panned east and was unable to load those
residential streets? That would explain how he has his own connected
network in the area that is connected to Conant Road but nothing else.
I would think it would actually be rather difficult to create a
self-contained network that is so close to existing objects. Potlatch
would tend to snap things to each other so they would be sharing some
nodes. That's my theory.
