Mumbai, the financial capital of India, has a population of over 1.24 crore and heavily depends on public infrastructure and transport for connectivity. With the city growing, Mumbai is undergoing a facelift when it comes to infrastructural development. One such infrastructure development is the development of the 21.8-km-long Mumbai Trans Harbour Link that will connect Sewri to Navi Mumbai’s Chirle that is located along the JNPT Road. The sea link will be developed by the MMRDA (Mumbai Metropolitan Region Development Authority).
About the Mumbai Trans Harbour Link
The Mumbai Trans Harbour link will be a six-lane expressway that will start at Sewri, cross the Thane creek and end at Chirle near Nhava Sheva. While the Mumbai Trans Harbour link project was planned the 1990s, it encountered many roadblocks. The project was revived in 2016 with prime minister Narendra Modi laying the foundation stone. In April 2018, construction work started on the Mumbai Trans Harbour Link, which was divided into three packages.
The first package is 10.38 kms from Sewri to Thane creek and is being developed by L&T and IHI Corporation. The second package is of 7.807 kms from Thane Creek to Shivaji Nagar, being developed by Tata Projects and Daewoo E&C. The third package is 3.613 kms that is being developed by L&T and will connect the Mumbai Trans Harbour link with state highways 52 and 54 and national highway 4B at Chirle, Navi Mumbai.
The fourth package of the Mumbai Trans Harbour Link is the Intelligent Transport Systems (ITS) that includes Toll and Transport Management System and Equipment Installation for the Project.

Mumbai Trans Harbour Link opening date
Expected to be completed by 2023, the Mumbai Trans Harbour Link will be the longest sea link in India. The construction cost of the Mumbai Trans Harbour Link is estimated to be around Rs 17,843 crores. Initially set to be built under the PPP model, the MMRDA later changed the model and executed the Mumbai Trans Harbour Link as an EPC model – Engineering, procurement and construction basis model. Around 85% of the project cost is financed by Japan International Cooperation Agency (JICA). Around 73% of the Mumbai Trans Harbour Link work has been completed as of March 2022.
Mumbai Trans Harbour Link features
According to the design of the Mumbai Trans Harbour Link, the Mumbai end will have a three-level interchange that will connect to the Eastern Freeway and the Sewri-Worli connector. There will be an interchange at Shivaji Nagar and Chirle on the Navi Mumbai end.
In the middle of the concrete Mumbai Trans Harbour Link, there will be a steel span of four kms that will allow easy movement of ships to the JNPT below the Mumbai Trans Harbour Link. The Mumbai Trans Harbour Link will also have view barriers at the Bhabha Atomic Research Centre (BARC) and noise barriers at Sewri mudflat area, which is a safe haven for migratory birds and flamingos.
The Mumbai Trans Harbour Link will also include amenities including an intelligence transport system (ITS) and variable message signs that are very important for a sea link. The maximum speed limit on the Mumbai Trans Harbour Link will be restricted to 100 kmph. Traffic on the Mumbai Trans Harbour Link will be managed using CCTV cameras by the Mumbai traffic control centre.
The Mumbai Trans Harbour Link will have a bird watching platform to view flamingos and other migratory birds. The MMRDA has built a 5.6-km temporary bridge for transporting equipment and people working on the project and this will be converted to a bird watching platform. This will be advantageous to the MMRDA, as it will save the cost of demolishing the bridge.

Reports suggest that the MMRDA, in 2012, had proposed toll rates for the Mumbai Trans Harbour Link as Rs 175 for cars, Rs 265 for LCV, Rs 525 for HCV and Rs 790 for multi-axle vehicles. However, due to increase in construction costs JICA, which is also the largest investor in the project, has suggested an increase in toll rates, which will be known closer to the date of completion and operation of the Mumbai Trans Harbour Link. To recover the investment in the Mumbai Trans Harbour Link, the MMRDA has plans to collect toll till 2045.

Mumbai Trans Harbour Link: Land acquisition
For the development of the Mumbai Trans Harbour Link, close to 130 hectares of land is required, of which CIDCO has contributed around 88 hectares.
