MMRDA to put up noise barriers at six flyovers

After installing noise barriers at Indian Institute of Technology (IIT) Bombay's Powai campus to cut decibel levels from the adjoining Jogeshwari-Vikhroli Link Road as well as at the Bandra Kurla Complex, the city's development authority will, in the next one year, do the same on six key flyovers in Mumbai.

The Mumbai Metropolitan Region Development Authority (MMRDA) has invited consultants to conduct a noise mapping exercise, analyse the level of noise and design suitable barriers for four flyovers — Sion flyover, Kings Circle flyover, Hindamata flyover and Lalbaug flyover — on the arterial Dr Ambedkar Road. The flyovers are flanked by residential areas, schools and hospitals on both sides. "The consultants will be given four months to complete the study, which will involve looking at the feasibility, preparation of designs as well as bid documents. Thereafter, we will call for bids for setting up these sound barriers," said Dilip Kawathkar, MMRDA spokesperson.

In May, MMRDA invited consultants to study the noise pollution levels and come up with a suitable design for noise barriers at Suman Nagar flyover near Chembur and Navghar flyover near Mulund.

"We have received bids from consultants and are in the process of picking one. After we receive an analysis, we will invite bids to install the noise barriers. The entire process should take at least six more months," a senior MMRDA official said. The development authority has pledged funds to the tune of Rs 37.6 crore towards the installation of noise barriers in the budget for the current fiscal.

The MMRDA, which had undertaken a study on noise barriers under the Mumbai Urban Transport Project, had first installed sound barriers costing Rs 8.68 crore on a 1,150-metre stretch at BKC, slashing noise in the area to 55 from 98 decibels.
