Approach road from other colony same survey number

I live in a house which has 2 entrances one from a 10 feet road and other from a private colony which has 30 feet road. Our entrance from 30 feet colony is closed from 2006 as the colony raised a compound wall. I would like to file a writ petition and get the access from the colony road. We both have same survey number and purchased from same vendor who had mentioned in the sale deed of private colony to give access to other properties belonging to vendor as common approach road. Is it possible and any other cases where the persons were able to win the case.
