The Union Cabinet, chaired by Prime Minister Narendra Modi, approved an 8.449 km extension of the Noida Metro Aqua Line at a cost of ₹2,390 crore. The project will connect Noida Sector 51 to Greater Noida Sector 4 and include five new elevated stations.

The extension will provide an interchange with the Delhi Metro Blue Line at Sector 61, improving access to commercial hubs like Gaur City Mall and IKEA, as well as IT offices such as Tech Mahindra and TCL Tech. It will also enhance connectivity to educational institutions like Delhi Public School and healthcare facilities including Kailash Hospital and Rama Hospital.

The project was approved on 11 November 2026 and is expected to expand the Noida Metro network to a total of 71.878 km. The extension aims to reduce travel times between key sectors in Noida and Greater Noida.
