September 24, 2025: Maharashtra Chief Minister Devendra Fadnavis announced on Monday that the country’s longest metro corridor, stretching 58 kilometres between Thane and Mumbai, is scheduled to become operational by December 2026. The line will connect the city’s eastern and western suburbs with Thane, easing one of the busiest commuting routes in the region.
The project integrates Metro Routes 4, 4A, 10, and 11. To support operations, 45 hectares of land have been allocated at Mogharpada in Thane for depot construction. The Chief Minister made the announcement while inaugurating the technical inspection and trial run of the Phase-1 Gaimukh Junction priority section, which links Gaimukh Village, Ghodbunder Road, Kasarvadavali, and Vijay Garden under Metro Routes 4 (Wadala–Kasarvadavali) and 4A (Kasarvadavali–Gaimukh).
Providing further details, he said the Ghatkopar–Mulund–Gaimukh stretch measures 35 km, comprising 32 km on Metro 4 and 2.88 km on Metro 4A. With 32 stations in total, the project carries an estimated cost of Rs 16,000 crore.
Once fully operational, the metro line is expected to serve over 2.1 million passengers daily, cutting travel time by 50 to 75%. Officials highlight that it will significantly decongest Mumbai’s roads while offering citizens safe, environmentally friendly, and reliable transport. Phased commissioning of Metro 4, 4A, 10, and 11 is targeted for completion by the end of next year.
Deputy Chief Minister and MMRDA Chairman Eknath Shinde noted that the 58-km elevated metro project is the first of its kind in India and will play a vital role in addressing Mumbai’s chronic traffic congestion.
According to MMRDA, inspection of the viaduct, tracks, and overhead equipment has been completed, with system integration and safety checks underway. Passenger safety, officials stressed, remains the highest priority, with Independent Safety Assessor certification and CMRS clearance required before public operations commence.
