TBM Mavala was delivered during the height of the pandemic. Weighing approximately 2,500 tonnes, the TBM was then lowered into the launching shaft in a fully assembled form. Another innovative method they adopted was to ‘rotate’ the TBM inside the shaft to start the second tunnel construction which saved them several months to dis-assemble, lift, transport, re-assemble & lower the TBM at a new location.
The Mumbai Coastal Road Project (MCRP) Phase-1 is a 9.98 km section from Princess Street Flyover at Marine Lines to the Worli end of the Bandra-Worli Sea Link (BWSL) involving sea front development and is a first-of-its-kind in India. The project is divided into 3 Packages viz. Package-I – From Amarsons Garden till Baroda Palace, Package-II – From Baroda Palace connecting it to Bandra Worli Sea Link & Package-IV – From Princess Street Flyover at Marine Lines to Priyadarshini Park. L&T is executing Packages I & IV for MCGM involving the construction of a 3.82 km long section over reclaimed land from Priyadarshini Park to Baroda Palace and interchanges at Amarson Garden and Haji Ali. Package IV involves the construction of a 2 km long twin bored tunnel along with cut & cover, ramp, etc. to form a combined road length of 4.06 km. When completed, it would be the largest and deepest bored road tunnel in India.
