Appu: <P>Why not? The government is "seriously" talking about 6-lane superhighways: toll roads with limited access, presumably like the US Interstate system, or more likely, like the British A- and M- road system. The plan is for a N-S-E-W cross, (Srinagar-Kanyakumari, and Ahmedabad-Calcutta, I think), and a "Golden Quadrilateral", connecting Mumbai, Calcutta, Delhi, Hyderabad, Chennai, Bangalore. (note: Kerala excluded: grounds for starting the "KLF"?

)<P>In the US, the estimate is $1million per mile of Interstate highway. We pay far less for our labor force and land, but we take longer and have far fewer machines, so I don't know the cost conversion. <P>Unlike the US, we don't have an empty continent. Nor do we have a surplus of concrete. We have to use our land and concrete wisely.<P>Such roads, to be any good, must go pretty straight, and have only gradual ups and downs. This means many long ramps, overpasses, bridges, some tunnels, etc., and hopefully they raise the road so it does not get flooded in every rain. These are concrete structures. Without planning, the spaces underneath will become, well, see Mumbai or Chennai or Miami to see what happens. <P>In India, getting cement /concrete is a big deal, so just the idea of synergizing shelter roofs and road beds is a huge cost-saver. The N-scare may shake out a lot of funds and land -acquisition permits that might not materialize otherwise. <P>Every village will want an access ramp to this system: let them put their shelters and cinema theaters under their on-ramps. <P>As for parking fighter planes, I think the Swedish do that already with their Viggens, and many forward areas in West Germany used such concepts because airfields were not expected to survive beyond the first hour of a Soviet invasion. <P>Saddam tried parking his Scuds under overpasses, but that just brought all the overpasses down. If he had them in underground chambers, he could have done much better. <P>The integration of the road system and civil defense, with modern community structures, may solve several problems. Makes it hard for anyone to oppose it. Also makes it easy to declare it an national priority, giving implementation authority to the Army. <P>I don't believe in underground railroads to move Agnis around. We have just so much railroad and so many trains that no enemy can hit all possible missile trains, so there is no need to park them underground.<P>Someone mentioned security and terrorist attacks. Sure, that's a problem, but its quicker to respond to an attack if it occurs near a major road, and besides, I am not suggesting that ALL our air force live under the road. Just enough to defend the road, and survive surprise attacks on airbases.<P>The road-building contractors should be, required to have their offices under the road, too. That way, they'll be a bit more careful about the sand fraction in the cement.<P>Finally, think of an India where all government offices are now underground. Appropriate, since they look like caves anyway now, and they keep them as organized as stone-age caves.
