The Pink Line, also known as the Ring Road Line, is an almost circular line that passes alongside the busy Ring Road in the national capital in a U-shaped pattern that witnessed massive traffic jams every day. The over 20 km line is a part of the entire 58.9 km corridor. When completed, it will become the longest Metro line in the country.
