As a Kenyan, I have been keenly following this Vision 2030 program and so far I somehow find it hard to crystallize how the objectives will be met.

It's fine to have a super highway with 12-lanes, in a normal functioning country the roads are that smooth all the time.

However, could you explain how the life of the people living Mathare North(located just next to the new highway) will change after the project is completed?

I've actually taken a wider perspective on this matter. The article I wrote (link provided in my firs post) tries to paint a big picture of my reasoning why this is not a sustainable model. The highway was just an example.

The people living in Mathare North (btw no offense here, just picked the place for illustration purposes)are not living under those conditions because there are no services such as banks near them. Even if the bank came to their houses what would they be sending to the bank?

I am compelled to total agreement with the boomerang and lend a new angle. In my opinion, Kenya should be working for itself and within itself to deliver the baby at 'term 2030'. We have institutions of higher learning churning engineers in their hundreds and we can only participate in our own infrastructure development as casual laborers. Local industries & intellectual capacities are at a loss for having not participated in such a crucial undertaking as Thika road. Vision 2030 is not something to be outsourced as we sit back in our hammocks marveling at Chinese ingenuity, but to be actively participated in by Kenya as the largest stakeholder.

Exactly, that's the point.
