The Mumbai Metropolitan Region Development Authority (MMRDA) has decided to install noise barriers on all the flyovers and railway overbridges that have been and will be constructed in the near future.
“The decision comes in the wake of the successful installation of such noise barriers at the Bandra-Kurla Complex, which now has acceptable decibel levels of 50-55 during the day and well below 45 at night,” said Ashwini Bhide, joint metropolitan commissioner, MMRDA. The MMRDA will spend Rs 10 crore for the project.
In the first phase of the project, the flyovers that will be provided with noise barriers are Sion Hospital Junction, Hindamata Junction, Thakur Complex, Malad Junction, Santacruz Airport Junction, Navaghar Junction and Dindoshi Junction, which are open to the traffic.
The railway overbridge at Dahisar has also been opened to traffic recently and will be provided with noise barriers.
The second phase of the project will see installation of noise barriers 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 railway overbridge and the Sahar Elevated Road will also be provided with noise barriers because they are scheduled to be completed in 2011. The length of all the 11 flyovers, two overbridges and the Sahar Elevated Road adds up to 12,750 m.
The MMRDA will undertake a noise mapping study at all these places and will install noise barriers on stretches depending on the necessity outlined by the study.
