Mumbai's Orange Gate–Marine Drive tunnel tunnel has reached a major milestone, having completed 1 km of underground construction. This progress marks significant advancement in the MMRDA's underground road link initiative for the Mumbai Metropolitan Region. The twin-tunnel project aims to offer an efficient east-west route through South Mumbai, one of the city's most congested zones.
Upon completion, the tunnel promises to cut travel time between Orange Gate and Marine Drive to just five minutes. The project encompasses two tunnels, together spanning over 7 km, with the ongoing tunnel extending about 3.45 km and reaching depths of up to 52 meters. The alignment of the tunnel passes beneath key transport infrastructure, including the Central and Western Railway corridors and Mumbai Metro Line 3.
Excavation is being carried out using tunnel-boring machine technology, which is particularly suitable for Mumbai's coastal geology. The complex underground environment, featuring existing transport infrastructure and utilities, demands precise monitoring and controlled operations to ensure minimal disruption to surface activities.
