The restaurant I was going to is above one of several tunnels under the city which hold I-35. Apple Maps assumed this meant the restaurant was actually on the shoulder of the interstate. Took me an extra 15 minutes to backtrack and get there on the correct surface roads. Immediately switched back to Google/Here

"You have arrived!".

With that said, you can always help out when you find quirks like this by reporting them. I went ahead and made a report for this particular problem, so it should hopefully get fixed shortly.
Try reporting it again. Sounds like your first report simply got lost somehow. I think every issue I've ever reported has gotten fixed, so it's not like they're habitually ignoring reports.
