Discussion: Broken Street Links

I've been noticing a ton of "street_not_found" errors in one of my scripts recently.  It seems that some streets have listed as connections tsids that aren't available?  They seem to be pretty far out from Kajuu, so perhaps they're streets-for-construction?  It'd be nice to know how to deal with them, or if they're a bug in my script.  

A couple of examples:
