Design and construction of Mumbai Metro Line 3 in India

摘要

Completion of the US$3.6 billion Mumbai Metro Line 3 in December 2021 will increase the system's capacity five-fold to 1.6 million passengers a day. With 26 underground stations and one depot, the new 33.5 km line will significantly improve connectivity between the northern and southern areas of India's largest city. It is being built directly under temples, residential areas and an airport. Close collaboration with stakeholders contributed to successful delivery and launch of the project's 17 tunnel boring machines. For rail systems, innovative technologies have been adopted to facilitate redundancy and ensure the safety and comfort of passengers.
