India To Get Its First Offshore Airport Near Mumbai; To Be Built On An Artificial Island

Given the boom of high-fliers in the country (credit ratings agency ICRA estimated that India saw about 15.3 million domestic air passengers in December 2024), the Indian government has chalked out plans to build the nation's first offshore airport near Mumbai. Reports further note that the upcoming airport, close to the Vadhvan Port, will be modelled around Hong Kong International Airport, and Osaka's Kansai International Airport, both of which are located on artificial islands, too.

Approvals For New Airport

Based on reports, the project is currently in its nascent stage and awaiting approval from the federal environment, defence departments, and the Government of Maharashtra. Once approved, the Airports Authority of India will undertake feasibility studies and revert with the estimated investment.

Notably, plans for Vadhvan port were first announced by Prime Minister Narendra Modi during an election rally last year. Then, he also noted that the Vadhvan port will be three times larger than India's largest existing ports and country's deepest. The proposed airport will be located 125 kms from Mumbai's existing Chhatrapati Shivaji Maharaj International Airport in Santa Cruz, Mumbai.

Making Commute Easier

According to reports, while the new offshore airport near Mumbai may be distant from the existing terminals geographically, a blueprint highlighting rapid transit options have been made to make the upcoming airport viable for travellers. The blueprint includes high-speed rail connectivity, with a proposed bullet train line between Mumbai and Ahmedabad that will halt near the Vadhvan airport, state reports. It further notes that two major inter-state highways—New Delhi-Mumbai and Mumbai-Vadodara—will also be rolled out as connections to the airport.

Challenges Ahead

While ambitious, the construction of the offshore airport near Mumbai could pose a challenge, especially as reclaimed land will serve as the inception. Assuring minimal ecological damage will be key.

Another major hurdle expected is ensuring sufficient passenger traffic, given the large-scale investments required to bring the project to life. In India's aviation history so far, airport terminals in smaller towns have not lured enough passengers yet. If all goes per plan, this upcoming offshore airport could be the winds of change.
