Big Flyovers vs Small Flyovers

• I will dedicate this post to the construction happening around the world which are related to flyovers.
• With great sadness I will like to say that mankind has still not reached the stage where they have perfected a way to build small flyovers.
• I stay in Bangalore and I will give one example.
• That is of St. Johns Hospital Signal.
• They built an underpass near Madivala Ayappa Swamy temple.
• They were planning to build an underpass at Koramangala water tank signal.
• After lying in limbo for more than one year, that underpass was abandoned way back in 2013.
• Now what we have at Koramangala water tank.
• It is the same old signal.
• But now they are going to build an elevated road read long flyover which will rise after the Madiwala Masjid and get down after Ejipura signal on Outer Ring Road.
• Below that long flyover there are seven crossings and/or signals.
• That is precisely my point.
• Why not build seven or perhaps four small flyovers instead of one big one.
• The answer lies here: We as humans have not mastered the technology to build small flyovers.
• Anywhere in the world it is not possible.
• Humans can build big and long like Electronics City 10 kms flyover but when it comes to building just a small flyover which may be 100 or 200 metres in length we do not have the resources or the technology.
• That is a failure of the engineers and the scientific community as a whole.
• In fact we as a human race should collectively hang our heads in shame as it is collective failure.
• My personal opinion is that if you cannot build small flyovers, do not build any flyover at all.
• At least do not build for private vehicles like cars and bikes.
• If you can and should build flyovers build for Metro.
• Much of the new Metro being built in India is elevated type.
• If bridges are to be built, build it for metros where trains will run ferrying hundreds of commuters and certainly not for private cars where often there is only the passenger-driver-owner travelling.
• Bridges should be built where there are obstacles which are non-human in nature like water body, river or valley when linking from one mountain (plateau) to another.
• Just building bridges over dry land and signals is a waste of resources and is the result of bad planning. 
• But metro is a different kind of vehicle (train) and requires a "dedicated corridor" for safe running and so the bridge has its meaning.
• Building long flyovers for private vehicles only makes encouragement for more and more private vehicles and result is catastrophe.
• Big flyovers ruin the scenery of a place and shift the traffic jams down the road.
• Sometimes we find jams on top of the flyovers and that is horrible.
• Tunnels are okay but there can be disasters on tunnels as well like we saw in the Sylvester Stallone movie "Daylight".
• Best is Underpass cum flyover like in Dairy Circle.
• Govt should encourage more underpass cum small flyovers.
• Now white topping of the roads is good because road life is increased and in the abscence of technology to build small small flyovers, it is the next best thing.
• If you do have to get trapped in a jam why not in "white topped" road.
• But, huge flyovers are ugly and mess and can never solve the traffic problems.
