Strengthening the connectivity between Delhi and Greater Noida, Noida Metro’s Aqua Line is all set to be linked with Delhi Metro’s Blue Line, via a 14 km-long link from Botanical Garden metro station to Noida Sector-142 metro station.

In an effort to strengthen the connectivity between Delhi and Greater Noida, the Metro authorities plan to link the Noida Metro's Aqua Line with Delhi Metro's Blue Line. Noida Sector 142 on the Aqua Line will be the linking station between the two lines, with a 14 km-long metro link starting from Botanical Garden station and ending at Noida Sector 142 metro station. The Greater Noida Authority has sanctioned the plan.

The 14 km-long metro link will run parallel to the Noida-Greater Noida Expressway, and passengers will be able to board the Pink Line or the Blue Line at Botanical Garden metro station. The link will be under the governance of the Delhi Metro but will be developed by the Noida Metro Rail Corporation (NMRC).

The Greater Noida Industrial Development Authority (GNIDA) has directed the NMRC to organise a Detailed Project Report (DPR) for the construction of the link. The estimated cost for the project is going to be Rs 1,500 to Rs 2,000 crore.

Alongside this project, the Delhi Metro authorities are also developing the Grey Line, which will bring improved connectivity to urban villages in Najafgarh. This line will be 5 km-long and will connect Dwarka on the Blue Line to Dhansa Bus Stand in Najafgarh, with Nangli lying in between. Previously, commuters in the area had to travel about 10 km to find the nearest metro station.
