Mumbai: Now, tetrapods at Mahim fort

Mahim Fort

To protect the walls of the historical Mahim fort from tidal currents, the Public Works Department (PWD) plans to install concrete tetrapods along the stretch of the fort. For the project, Rs 2 crore has been sanctioned.

Tetrapods are 'four-legged' concrete structures which reduce the force with which water hits shores. They will be installed once the existing stones have been fixed. "The concrete tetrapods that will be put up along the 100-metre stretch of the fort will protect the walls that are exposed to tidal currents. It will also prevent soil erosion on the beach," said a PWD engineer.

Officials said that the boulders that have been washed ashore will be lifted and rearranged. Under Phase-II of the project, the tetrapods will be installed at other spots along the Mumbai coastline, depending on the availability of funds.
