  Here is a TIGER 12 vs OSM comparison.   They cyan inner arc exists in 
TIGER 12 but not OSM.   However, it originally started out in TIGER 07 
but was removed from OSM because it doesn't exist.

  One way around this is to do a TIGER 12 VS 07 compare to start with, 
then compare that to  OSM to detect improved geometry or new roads.
