There has been a lot of noise made about the access roads. If the underpasses being built now from Windsor Manor to Hebbal flyover get done by the promised end of March, the six lane road from the Hebbal flyover to the airport should be a smooth ride with a total ride duration of about 40-45 minutes.., so do not sweat. Of course the underpasses are in addition to the connectivity from the outer ring road that encircles Bengaluru to the Hebbal flyover.
