Mumbai's Goregaon-Mulund Link Road Tunnel Excavation Begins Under National Park
In Mumbai, a big city in India, workers are building a new road that goes under a huge park called Sanjay Gandhi National Park.
The road is called the Goregaon-Mulund Link Road.
To build it, they use giant machines called tunnel boring machines, which dig tunnels like giant worms.
One of these machines is named Tulsi, and it has started digging.
The plan is to build two tunnels, each about 5.3 kilometers long.
The tunnels will connect the eastern and western parts of Mumbai.
The new road will have safety features like cameras, lights, and firefighting systems.
It will also carry big water pipes to help the city.
When it is finished, people will be able to travel much faster, saving time and fuel.
The project is expected to be done by February 2029.
TBM 'Tulsi' has begun excavation for one of two 5.30-km, three-lane tunnels beneath Sanjay Gandhi National Park in Mumbai.
The twin tunnels will connect Dadasaheb Phalke Chitranagari in Goregaon East with Amar Nagar in Mulund West.
The 6.62-km package includes 17 cross passages, twin-box tunnels, approach roads, and advanced safety systems.
TBM-2 is being assembled and is scheduled to begin excavation in October 2026, with completion targeted for February 2029.
The link road is expected to cut travel time from about 90 minutes to 20 minutes and ease congestion on Mumbai's arterial roads.
