So that Oakwood Realignment thread got me thinking about streets I've noticed that were different 40-50-60+ years. I've found these thanks to my near obsession with the DTE Aerial Views website.

And while it wasn't a realignment, the renaming of Hunter Blvd. to Woodward in the 90s and Woodward became Old Woodward.
