Airport to get trumpet junction flyover

Airport to get trumpet junction flyover
New Indian Express

BANGALORE: For the first time in India, a trumpet-like design flyover will be built. This interchange will be a part of the six-laning of the Bangalore-Hyderabad NH 7 (Bellary road) built by National Highway Authority of India (NHAI). The interchange will fly over the rail crossing just before the international airport and deliver vehicles directly in front of the terminal.

The total land required for the project is 60 acres. “Preliminary notification has already been given and the final notification will be given soon,” Vinay Kumar, Principal Secretary, Infrastructure department said.

The cost estimated is 38 Crores. The Build Own Operate and Transfer (BOOT) process is yet to be done. “It may be given to a private firm for a period of 20 years. They will be able to recover the amount through the toll,” he said.

“The international airport was itself cleared in March, so these plans were on a hold. Now the work will be speedy,” he said.

The trumpet-like flyover, which will take off from the Bangalore-Hyderabad highway, will pass the highway and the railway track, and descend to the International Airport.

Bangalore to Hyderabad traffic will continue without hindrance along the six-lane highway. Hyderabad to Bangalore-bound traffic will also continue without hindrance.

Commuters from Bangalore to international airport will take the left ramp, go into outer loop of trumpet and continue down ramp straight to terminal, while commuters from Hyderabad side of highway take the surface road into the airport.

Those coming out of international airport heading towards Bangalore city will take the surface road towards the city and those heading towards Hyderabad side will take the ramp from the airport to the inner loop of the trumpet and exit out on the National Highway.

The trumpet interchange is so called as the design of the ramps and the concentric loops resembles the spiralling design of the musical instrument. Such a flyover has not been built in India so far, though there is a plan for a trumpet exchange on NH 79, at Krishangarh-Nazirabad in Ajmer district of Rajasthan.
