Tathya.in has some interesting tidbits on this. Following is an excerpt.

Minister was speaking in the High Level Clearance Authority (HLCA) on 17 November.

HLCA Chaired by Naveen Patnaik cleared the proposal of 4-laning of Sambalpur-Rourkela Highway on PPP Mode with an investment of Rs.1270 crore.

He said by slapping tool tax on the commuters and funding the project is passé.

Now while roads are coming up in a big way, lands are identified at some vantage points by the side of the roads.

These places can be handed over to the developers so that they can develop shopping malls, housing projects and this should be included in the package.

And this initiative will lessen the burden of tax payers, who are forced to pay huge toll tax for years to come.

Secondly Minister said that while we are going for expansion of the Highways, encroachment of land is posing a big problem.

… It would be a better proposition to acquire land and lay the road in such a way that more space is left inwards.

So that later that space can be used for expansion of roads and no body will be able to encroach upon and inside the highway, said the Minister.
