Infrastructure projects to get sound barriers

Mumbaiites alarmed by the increasing sound pollution because of the metro, monorail and road projects being undertaken in the city can now breathe a little easy.

The Mumbai Metropolitan Region Development Authority (MMRDA) is now contemplating installing sound barriers for all infrastructure projects.

“We had already planned to set up noise barriers on all flyovers and railway over bridges. Now we will ensure similar barriers are set up at places where we are conducting infrastructure work so that people are not hassled,” a senior MMRDA official said, on condition of anonymity, because he is not authorised to speak to the media.

The MMRDA, in December last year, announced a Rs 10 crore project for installing noise barriers on all flyovers and railway over bridges that have been and will be constructed in the near future.

The decision came in the wake of the installation of noise barriers at the Bandra-Kurla Complex.

A noise barrier is an exterior structure designed to protect sensitive land from noise pollution. Noise barriers are generally used for mitigating roadway, railway, and industrial noise sources. They are constructed using a combination of steel, concrete, masonry, wood, plastics, insulating wool, or composites.

Under the MMRDA’s original plan, noise barriers were to be installed in a phase-wise manner across the city.

In the first phase of the project, the flyovers will be provided with noise barriers at Sion Hospital junction, Hindmata junction, Thakur Complex, Malad junction, Santacruz Airport junction, Navaghar junction, Dindoshi junction and the Dindoshi rail over bridge.

The second phase of the project will see noise barriers being installed on flyovers at King’s Circle-Tulpule Chowk, Lalbaug junction, Barfiwalla junction and Suman Nagar junction, which are under construction and will be completed soon. The Milan rail over bridge and the Sahar Elevated Road will also be provided with noise barriers once they are completed in 2011.

The noise barriers that are being installed will help bring down decibel levels by 50-55 during the day and well below 45 during the night.

The MMRDA will now add the nine metro lines and the monorail network to the list of infrastructure projects which will have sound barriers.
