The Mumbai Metropolitan Region Development Authority (MMRDA) has decided to restudy the plan to install noise barriers on all 11 flyovers in its jurisdiction.


Instead, the MMRDA is likely to install noise barriers only on those flyovers where surrounding areas will be affected due to vehicular traffic.

The MMRDA had appointed consultant Central Road Research Institute (CRRI) to carry out noise-mapping studies at these flyovers.

Based on this, it had, in March, decided to install noise barriers on all 11 flyovers in two phases.

In its new study, the MMRDA is examining whether vehicular traffic on the flyovers is really affecting surrounding areas.

“The study on installation of noise barriers is going on, in which we are examining to what extent vehicular traffic on the flyovers is affecting the surrounding areas.

At some places, we have found noise generated by the traffic at ground level is much more than the noise on the flyover, so installation of noise barriers on these flyovers may not help,” said MMRDA commissioner UPS Madan.

Based on the findings of this new study, the MMRDA will not install noise barriers on flyovers where surrounding buildings are at a distance and thus will not be affected by vehicular traffic on the flyover and in cases where noise on the street (ground level) is at a relatively higher level than on the flyover.

The MMRDA has also decided to install noise barriers on some stretches of the eastern freeway, which are flanked by residential areas.
