When the high speed Metro Airport Express line will pass through Dhaula Kuan, it will not be heard or seen.
The Delhi Metro Rail Corporation (DMRC) is installing specially designed parapets made of polycarbonate sheets at the Airport line section near Dhaula Kuan in south Delhi, one of the city’s busiest traffic intersections.
The blue-coloured polycarbonate sheets will grace both sides of the Metro track, which crosses eight roads —Ring Road, National Highway-8, Ridge Road and Sardar Patel Marg. All these roads carry heavy volume of traffic towards the Indira Gandhi International Airport and Gurgaon.
These sheets will ensure that the Metro will not be seen from the road. “Metro parapets are usually built of concrete, but the 1.9 m high polycarbonate sheets were preferred at Dhaula Kuan as they will significantly improve the aesthetics of the area,” said a DMRC spokesman.
DMRC claims that not only will these sheets will aesthetic but will also act as sound barriers. “The cleaning process is also simpler than ordinary parapets as these polycarbonate sheets can be cleaned with soft wet cloth or sponge,” he said.
“We are using polycarbonate sheets as parapets for the first time in India. Internationally, they have been used in the construction of some Metro systems in Europe,” he said. “These will provide a sleek international look to the elevated portion of the Airport Express Line.”
The sheets will be installed along a length of 1,300 m, including both sides of the track above Dhaula Kuan intersection.
The sheets, each of which is two metre wide and 6 mm thick, are being affixed on fire retardant and ultra-violet resistant aluminum alloy structure using gaskets and self drilling zinc coated screws.
