Welcome to OSM, and thanks for your contributions. A lot of road data in the US has been untouched since it was imported from TIGER in 2007/2008. You will often find roads that were planned but never actually existed, or unmaintained/abandoned roads. In these cases it looks like the roads exist in some form but are probably not navigable by cars. Please take a look at the wiki page for abandoned roads: https://wiki.openstreetmap.org/wiki/Key:abandoned:highway . Let me know if you have any questions, and happy mapping!
