I don't think any thing is going to change with the new airport. If you want the truth straight, on a peak hour traversing the current Airport Road, Domlur will take you half an hour to 50 mins. This is an overused road, how do i know? i take this road every day. If you are comming from Marathahalli side nothing better.
The new Airport is a bit difficult to reach, may involve about 30 mins-1hr of extra planning for most and once new infrastructure is in place there is barely any diff(this will look more normalized if you consider that after two years it would take the same time but more effort to reach the HAL Airport then). The cost of travel ofcourse is more because of UDF, but even the current HAL Airport charges fees(airport charges), that you do not see.
Many people say leaving HAL airport open will solve all the problems, but who is to answer for all the development that has been done in the new airport and surrounding regions. What about people who will choose connecting flights from Bangalore.
Also, this time government has responded well to connectivity to Airport leading to a very good infrastructure in that area in about 2-3 years(for a change). This airport has given multitudes of business oppertunities like good bus connectivity, averagly priced taxis, hotels, shops, high speed railway connectivity to chennai and neighbouring places, good development oppertunity in North Bangalore(more office space, if the government want, it can repay for the mistakes they did with developing south and east Bangalore). This will definitely mark a new phase of development for this city.
Also what most people ignore to say is that BIAL wants to be the sole airport operator with 150kms radius of Bangalore. This does not mean that they will run only from a single terminal, HAL will be commissioned by them if need be in some later stages(as i see this is not necessary atleast till 2010). If our government stop trying to stop development of the private projects(BIAL, NICE) we will have a better life. Patel even commented that he likes the improvement of existing airport over building Airport with PPP. I really doubt anything can be improved in the existing HAL Airport(ever been to pickup some one, i once spent more time waiting for traffic to clear in the road leading to the terminal than my dad took to travel half way from Hyd and land and pickup the baggage and walk the place the car was in a jam) and secondly how far can we go, we are not building multistoreyed car parking here, Airport needs a hell lot of space, this is available at BIAL(though current most of it will be used for business, but once the locality becomes better, they will most probably convert most of it to airport space).
It will most definitely be the elevated expressway at Hosur road at guns point next, wanna bet.
They will find something defective like road is not wide enough/toll charges overwhelming/bad ride quality/anything like it and then make a hell of a story with it and more Misras will be born. If this keeps happening PPP project have no hope here, nor do we for any infrastructure or cheaper living in future.
Finally lets give them a chance to proove themselves and show it to them as a challenge rather than plain complaining.
