Mumbai Trans Harbour Link Set to Transform Connectivity: Prime Minister Modi Inaugurates India's Longest Sea Bridge


In a historic moment for Mumbai, Prime Minister Narendra Modi is set to inaugurate the Mumbai Trans Harbour Link (MTHL), officially known as Atal Setu Nhava Sheva Sea Link, on Friday, 12 Jan 2024. This engineering marvel, spanning a length of 21.8 kilometres, is the longest sea bridge in the country. Constructed over seven years by the Mumbai Metropolitan Region Development Authority (MMRDA), the MTHL promises to revolutionize travel between Mumbai and Navi Mumbai, significantly cutting down commute times.

Connectivity and Infrastructure:

The MTHL is designed to last a century and boasts three interchanges connecting various highways and roads. This expansive infrastructure is expected to accommodate a substantial increase in traffic, projecting a growth from 39,300 passenger cars in its initial opening year to an estimated 1.03 lakh cars by 2032, according to the MMRDA's quarterly progress report.

Reduced Travel Time:

One of the most anticipated benefits of the MTHL is the remarkable reduction in travel time. The bridge promises a mere 20-minute drive from Sewri to Chirle, offering commuters a swift and efficient alternative to the current routes between Mumbai and Navi Mumbai. This development is expected to ease congestion on existing routes and enhance overall connectivity in the region.

Bus Services and Deliberations:

While the inauguration is cause for celebration, transportation authorities are yet to finalize decisions regarding bus services on the toll road. The Navi Mumbai Municipal Corporation, responsible for bus services on the MTHL, is deliberating the rollout of these services. Municipal Commissioner Rajesh Narvekar highlights the need to assess passenger demand in less-densely populated areas served by two interchanges—Chirle and Ulwe—on the bridge. The absence of bus stops along the bridge adds to the complexity of planning public bus services.

Toll Considerations:

The Maharashtra government has disclosed a toll of Rs 250 for one-way single-journey vehicles, with tolls for other vehicle types yet to be announced. The MMRDA quarterly project report from January to March 2023 proposed a toll of Rs 550 for buses. However, uncertainties over toll payments have delayed the finalization of bus services. The Brihanmumbai Electric Supply and Transport (BEST) is also awaiting clarity on toll-related matters before deciding on bus services.

Impact on Pune-Bound Traffic:

The MTHL is not only a boon for Mumbai and Navi Mumbai but is expected to have a broader impact on traffic to Pune. Once the Expressway shortcut from the MTHL at the Chirle end is built, traffic to Pune is projected to see a substantial increase. The elevated route between Chirle and Palaspe will drastically reduce travel time, making the commute more efficient for travellers heading to Pune.


The Mumbai Trans Harbour Link is poised to be a game-changer in the region's transportation landscape, providing a seamless connection between Mumbai and Navi Mumbai. As Prime Minister Modi inaugurates this marvel, the anticipation of reduced travel times, increased connectivity, and improved infrastructure adds to the excitement surrounding this momentous project. The MTHL marks a significant step towards modernizing and enhancing transportation in one of India's busiest metropolitan areas.
