The Mumbai Metropolitan Region Development Authority (MMRDA) has started installing vehicle crash barriers on the outer sides of the Mumbai Trans Harbour Link (MTHL) carriageway. The overall height of these hybrid crash barriers is 1,550 mm. The height of the barriers’ concrete section is 900 mm while the metal railing above them is 650 mm tall.

Initially, the MMRDA had decided to opt for a five-foot wall on either side of the 22-km-long structure. However, this would block the sea view and create a tunnel effect for drivers.  The concrete-metal barrier adopted for the MTHL complies with the international standard EN 1317. Physical crash tests were carried out abroad as per international safety standards.
