Hi @Adithyan45 , welcome to Connect, and thank you for asking about road editing.
As you said
do you mean that the edits are still pending?
In that case, this can be considered good news because the changes passed the initial inspection. Google Maps can take up to 90 days to approve (or reject) an edit. This depends on several factors, such as the population density of the area, the complexity of the added road, the type of road, and so on.
There’s no single answer, and it’s not possible to be more specific without seeing your edits.
Can you send us a link in Google Maps to the locations of the added roads?
On the meantime I suggest you to read 3000+, and counting. My tips for adding roads in Google Maps
Thank you for this response 
You are welcome, @Adithyan45
