Environmental impact
The site needed the Ulwe river to be diverted, a hill to be levelled and mangroves on the site to be cleared. The environmental clearance (2010) came with 32 conditions, including compensatory mangrove planting (about 350 hectares at Dahanu); the Gadhi river was left untouched after the runway layout was changed. Environmentalists warned of flood risk in the low-lying area.
About the project
Phase 1 was built at a cost of ₹19,650 crore and inaugurated by the Prime Minister on 8 October 2025. Commercial flights began on 25 December 2025. At full build-out the airport is planned for 90 million passengers a year.
