Hi AardvarkPestPro,
To report an issue with a route, road, business and more follow the steps in Report an incident in Maps on your iPhone:
"From the main Maps screen
- Tap your image next to the search field, then tap Reports.
- Tap Report a New Issue at the bottom of the screen, then select the type of report.
- Add the information for the issue, then tap Send in the upper-right corner.
Under Incidents Reported, you can only see the type and number of incidents previously reported."
Note in the screenshot on that page there is an option for "Report Place Issue" and choosing that will present you options to have the business or location reviewed for updating or changes.
Regards.
