this was driving me crazy for a recent client, 2 very old profiles with “driving directions” to locations that didn’t exist. I tried contacting MapQuest on their contact page which it says can be used for fixing information (spoiler: nope!) and they simply replied to me with the following message instead:

Re: Incorrect Business Information

Thank you for contacting MapQuest,

We are no longer adding or updating business information on our site. We receive data from our partners such as:
Yext, http://www.Yext.com

Yelp, http://www.yelp.com

data axle, https://local-listings.data-axle.com/

Here, Try adding or editing it through our partner Here.com since they also provide our mapping data.

https://mapcreator.here.com/?site=here_com_contact&l=XX.XXXX,-XXX.XXXX,XX,normal

foursquare, https://foursquare.com

Tomtom, tomtom.com

We suggest you contact them directly to see if they have a listing for you and if it needs updating, or you can have them add one. Since they share their data with us, we will get updates from them. However, if you choose for the listing to be removed altogether, I can do that. Just let me know.

I hope you have a great day.
