It seems to be that BDA is doing this out of self frustration, or desperation to meet deadlines towards making the BIAL route signal free. So much so that they are testing the uncompleted CBI junction by allowing vehicles to go through always in only one direction at any time.
Though the CBI magic box is a much better designed magic box than the BDA junction one (which by all means needs to get the "Worst infrastructure project of the year award"), one still cant understand how this magic box is gonna work. Lets try and do some analysis here:
There is one magic box between RT nagar entrance and the other side, and there is another more nearer to the police station side. one possible way of traffic entry and exit could be as shown below:
The question mark in this figure is the place where there could likely be a signal of some sort !! and maybe more confusions too in future! Whatever it is BDA, you have got the access to BIAL through somehow and thats probably what you would be looking at in future as well and not really bother how the other people would fight it out isnt it? :)
I for once want this magic box to be opened up real soon and I am tired of all the dust and chaos this junction is undergoing at the moment. Lets hope for the best!
So common BDA open up those barricades soon will ya?
