BMC Starts Removing Mastic Layer from Mumbai Coastal Road

25 Feb 2025 CW Team

The Brihanmumbai Municipal Corporation (BMC) has initiated the process of removing the mastic layer from the Haji Ali bridge as part of on-going maintenance work under the Mumbai Coastal Road (South) Project. The layer was originally applied as a protective measure to safeguard the road during the monsoon season and to prevent the expansion of joints, ensuring the road surface’s durability.

Before July 2024, the road was paved with asphalt, but some sections developed widened joints. To prevent further deterioration and maintain road strength, the mastic layer was applied in specific areas. The Mumbai Coastal Road (South) remains structurally sound, without any cracks or potholes.

The removal of the mastic layer is being carried out efficiently, with fresh asphalt set to be laid within the next few days to restore the road to its original condition. This will ensure smooth and safe travel for commuters.

Recently, images and videos of the additional mastic layer on the bridge near Haji Ali have been widely circulated, leading to speculation about possible construction flaws. However, the BMC has clarified that these patches are part of preventive measures rather than signs of damage. The mastic was applied to reinforce the road surface and mitigate the risk of potholes during the monsoon season.

The northbound lane of the Mumbai Coastal Road, connecting Chowpatty to Worli, was opened for traffic in July 2024 following proper asphalt layering. Minor joint expansion was observed over time, prompting the application of the mastic layer as a precautionary step. A new asphalt layer, meeting all technical standards, will soon be applied, and the road’s appearance is expected to be fully restored within 15 to 20 days.
