Mumbai Metropolitan Region Development Authority and City and Industrial Development Corporation have jointly decided to build a Rs 15,000 crore and 35 km long Airport Express metro line starting from Chhatrapati Shivaji Maharaj International Airport (CSMIA) and directly connecting the upcoming Navi Mumbai International Airport. The metro line will have a daily ridership of 9 lakh passengers and will be jointly executed by the two infrastructure building nodal agencies including MMRDA and CIDCO. Elaborating that MMRDA will build metro line 8 from Chhatrapati Shivaji Maharaj International (CSMIA) to Mankhurd (11.1 km) through Delhi Metro Rail Corporation (DMRC), while City and Industrial Development Corporation (CIDCO) will be extending the line from Mankhurd to Navi Mumbai airport. There is no mass rapid transport system (MRTS) between this airport and the international airport in Mumbai. The metro for Navi Mumbai airport has been on the MMRDA’s master plan since 2014.
New metro line will be partially underground on the Mumbai side and the line is likely to be built underground from Andheri to Eastern Express Highway at Ghatkopar and from Ghatkopar to Mankhurd it will be elevated via the Ghatkopar-Mankhurd link road and the project is slated to be completed by 2025.
