Mumbai Trans Harbour Link Route Map

  • The 22-km-long Mumbai Trans Harbour Sea Link connects Sewri in Mumbai to Chirle in Navi Mumbai. The link offers a direct route for commuters and vehicles travelling between these two points. According to the plan, the link ending in Mumbai has a three-level interchange, connecting the Sewri-Worli connector and the Eastern Expressway.
  • There will be an interchange as well at Shivaji Nagar and Chirle on the Navi Mumbai end. Furthermore, a notable steel span of 4 kms will be incorporated to facilitate easy movement of ships to the Jawaharlal Nehru Port Trust (JNPT) situated below. This dedicated facility will ensure efficient maritime operations.

History (Necessity Breeds Innovation)

The seeds of the Mumbai Trans Harbour Link were sown in the 1990s, amidst the burgeoning traffic and congestion plaguing Mumbai. With six existing bridges struggling to meet the demands of growing traffic, the need for a comprehensive solution became evident. The Mumbai Metropolitan Region Development Authority (MMRDA) embarked on studies to address these challenges, leading to the proposal for the Trans Harbour Link in 2012. However, the journey from proposal to fruition was riddled with hurdles, marked by delays and multiple attempts to kickstart the project.

Planning (Overcoming Obstacles)

The planning phase of the Mumbai Trans Harbour Link witnessed various attempts to bring the project to life. From initial proposals by private entities to subsequent government-led initiatives, each attempt faced its share of challenges. The transition from private-public partnership (PPP) models to cash contract basis underscored the complexities involved in financing and executing such a massive infrastructure project. Environmental concerns, clearance procedures, and stakeholder negotiations added layers of intricacy to the planning process.

Construction (Building Bridges, Overcoming Challenges)

Construction on the Mumbai Trans Harbour Link commenced in April 2018, marking a significant milestone in the project’s timeline. However, the journey was not without its challenges. The COVID-19 pandemic, unforeseen delays, and technical complexities posed formidable obstacles along the way. Despite these challenges, the dedication of engineers, workers, and project stakeholders ensured steady progress towards completion. The bridge’s inauguration in January 2024 culminated years of planning and perseverance.

By addressing environmental concerns and securing robust financial backing, the Mumbai Trans Harbour Link project charted a course towards connectivity and sustainable development.

Switching Gears

From PPP to EPC

In August 2013, the Mumbai Metropolitan Region Development Authority (MMRDA) made a pivotal decision to abandon the Public-Private Partnership (PPP) model in favor of an Engineering, Procurement, and Construction (EPC) approach for the Mumbai Trans Harbour Link project. This shift in strategy aimed to streamline execution and address funding challenges. The move garnered interest from the Japan International Cooperation Agency (JICA), signaling a new phase in the project’s development.

Environmental Hurdles

Protecting Biodiversity

The project encountered a significant setback in April 2015 when the FAC of the MoEFCC withheld clearance due to environmental concerns. The proposed bridge’s impact on mangroves and the flamingo population raised red flags, necessitating comprehensive studies and safeguards. Despite challenges, subsequent clearances from authorities such as the MCZMA and the Forest Advisory Committee marked progress in navigating environmental hurdles.

Financial Support and Clearances

A Path Forward

In February 2016, JICA stepped in with a substantial loan agreement, offering 80% of the project’s total cost at favorable interest rates. This financial support, coupled with clearances from various regulatory bodies, provided momentum for the project’s advancement. With JICA’s formal approval and the initiation of the bidding process, the Mumbai Trans Harbour Link edged closer to realization.
