The approval of a road may takes 1 to 90 days for being approved.
Can you kindly share the link in Google Maps of the road? This may help to check it.
In this case I suggest you to add the road in small steps, as they can be approved faster.
Of course there are other ways to add roads:
Another option is to write a post to the Google Maps help community, providing a link to the road and a link to an official Maps (publicly accessible and issued by a Local Authority) for the community to escalate the issue to the team
