I would If I could 35: Self sustaining roads

 national highways keep getting rebuilt, destroyed and they are also an embarrassment to a country depending on it's status. The cost of building, maintaining is a forever endeavor. the following solution not only solves this problem, headache forever for the government, people, users and also boosts morale of the defense personal. It will stop corruption of bureaucrats forever because they no more can buy/own land next to these highways.

Equal width of the road adjacent to the national highway is owned by the government forever. Blocks of that land is made into annually rent-able property. All such properties can only be rent-able by ex service men of a minimum of 5 years of experience. No politician or bureaucrat or anyone can own or have this. As long as the rent is being paid on time, the person can use the land forever for commercial (non religious) purpose. Upon their death, it is auctioned again. Sun lending or sun renting isn't allowed. Another layer of restriction is that only the people of that state by birth are allowed to have this. 100% of the use, revenue, profit of such land should be directly, passively, indirectly should only belong to the service men to whom the land is allocated. None is allowed to have 2 adjacent blocks, this ensures that no big sharks can swallow the whole thing. Each service men will have a cap of how many he such plots he can have. Someone with 10 years can get 2 adjacent plots. No other hierarchical based privileges.

1. Bureaucrats or politicians can no more buy land with insider information which is misuse of office
2.  The rent should be such that it funds the forever maintenance of the road including lights, barricades, painting etc.,
3. 100% guaranteed livelihood for the ex service men which boosts the morale  of the defense and keeps the defense mostly young. 
4. No more looting of money by politicians who keep getting funding for roads, which incentivizes them to make the roads short lived to ensure repeated routine funding. 

The same can be replicated in cities but most MLA, MPs politicians depend on such routine funding by the government so that they can get their share of the loot from the party affiliated contractors.
