MMRDA completes work on Bandongari Hillock retaining wall to prevent landslides

The Mumbai Metropolitan Area Development Authority (MMRDA) has completed the retaining wall covering the Bandongari mound on the Western Express highway to prevent landslides especially during the rainy season. Soon the idea will be called in order to give an artistic look to this new wall, SVR Srinivas, the MMRDA commissioners told the Free Press Journal.

In 2020, there was a major landslide on the WEH near Kandivali Bandongari Hillock due to heavy rain affecting traffic. Although there were no casualties or injuries in the landslide, traffic remained affected for a few days after the incident. Following which the MMRDA, which is responsible for maintaining and taking care of WEH, had drawn up a plan to erect a wall to protect the road and motorists from a possible landslide during the monsoon seasons.

MMRDA Commissioner Srinivas further stated that the lifespan of these methodologies is high, it is an almost permanent solution.

The Bandongari Hillock has a prestressed buttressed retaining wall. Cables have been anchored to the bedrock, which prevents the loose rock or rock mass from collapsing. Drainage holes have also been made so that rainwater can flow easily.

In fact, other government agencies like PWD, BMC are in contact with MMRDA to understand the methodology so that the same can be adopted at the Mumbai -Pune Expressway Ghat section among other similar places where there is a risk of landslide, an official said.
