Mumbai International Airport Limited (MIAL), the operator of Chhatrapati Shivaji Maharaj International Airport (CSMIA) and one of the world’s busiest single-runway airports, has announced a temporary closure of its cross runways. This scheduled closure is part of the airport’s comprehensive, annual post-monsoon maintenance plan, aimed at ensuring continued safety, security, and efficiency.
Both cross runways—RWY 09/27 and RWY 14/32—will remain non-operational on November 20, 2025, from 1100 hrs to 1700 hrs IST. The six-hour closure is designed to guarantee the safety, reliability, and compliance of the runways with global aviation standards.
The maintenance work will be extensive, including detailed inspections, surface repairs, and technical assessments of crucial components such as runway lighting, markings, and drainage systems. MIAL emphasized that this post-monsoon maintenance is an integral part of CSMIA’s year-round operational readiness programme, reinforcing its fundamental ‘safety-first’ approach.
To minimize passenger inconvenience and allow for seamless coordination, a Notice to Airmen (NOTAM) was issued well in advance. This proactive communication allowed all stakeholders, including airlines, to adjust flight schedules and manpower planning accordingly.
