In yet another connectivity momentum, the Maharashtra State Road Development Corporation (MSRDC) has planned to construct an underground road connecting Thane and Borivali, under the supervision of Urban Development Minister Eknath Shinde. The estimated cost of this project is Rs 11,235.43 crore and the twin tunnel connecting Thane- Borivali would make travel between faster for commuters, as well as aid to minimise current traffic congestion on Godhbunder Road. The route would feature an 11.8 km long connecting road with 10.25 km long two three lane tunnels built beneath the Sanjay Gandhi National Park, running from Tikuji-Ni-Wadi in Thane to the western expressway in Borivali.

Considering that the tunnel will pass through Sanjay Gandhi National Park, MSRDC has taken special precautions to avoid causing harm to the park's biodiversity by using tunnel boring machinery to avoid upsetting the lives of the park's animals and flora. The Thane-Borivali tunnel would necessitate the acquisition of 16.54 hectares of private land and 40.46 hectares of land within the Sanjay Gandhi National Park. The project, which is scheduled to begin in March 2022, is expected to take five and a half years to complete.

There will be cross tunnels every 300 m, and the design will allow vehicles to travel at a top speed of 80 km per hour. The 60 minute trip time will be cut to 15 to 20 minutes, resulting in time savings and a reduction of 10.5 lakh metric tonnes of fuel. The initiative will contribute to a 36% reduction in carbon dioxide emissions, assisting in the maintenance of environmental balance. Similar features will be implemented, including a drainage system, a smoke detector, and a jet fan. Special measures will be taken to ensure that the air within the constricted tunnel remains clean and fresh.

The Thane-Borivali subterranean tunnel's detailed project report (DPR) has been finished, and land acquisition work has begun. Additionally, the project is exempted from the requirement for environmental approval. Eknath Shinde, Maharashtra's Infrastructure Man, is devoting his efforts and energy to provide the State with world-class infrastructure facilities.
