National Highways Authority Of India [NHAI] — high number of tolls

Hi,
I am basically from karnal and working in Gurugram. There is a rule that there will be a gap of 60 km between 2 tolls but in 55 KM there are 3 tolls ie. karnal, Panipat and ghannaur.
One more thing, Why is this ghannaur toll being made ?
They are not doing any work from last 4 year even they have broken down all the roads and chance of accident becomes so much high. I kindly request you to give me the resons for my questions listed below :
1. Why is this ghannaur toll being made ?
2. Why there are 3 tolls between karnal and sonipat ?
3. Why the work is not going on National Highway even after taking tolls from customers.
4. Kindly request you to revert me at [protected]@yahoo.com or call me at [protected]
