The Pink Line underground construction of Bengaluru’s Metro network is in final phases, and is known for its extensive underground metro tunnel. This tunnel connects Bannerghatta Road to Nagawara, and work is expected to be completed by August this year.

The 13-km tunnelling project has been taken up in three phases. The first two phases have already been successfully completed, with the third phase nearing its conclusion. In the third phase of tunnelling, it stands at 94 percent completion rate. As per Bengaluru Metro Rail Corporation (BMRCL), this critical phase involves the excavation of 935 mtrs. of tunnel between KG Halli and Nagawara, utilising advanced tunnel boring machines named Tunga and Bhadra. Tunga is expected to finish its part of the tunnel by 31 July, 2024 while Bhadra is anticipated to reach the end of its tunnelling process by 31 August, 2024.

The successful completion of the tunnelling phases will pave the way for subsequent track laying and civil works, along with the installation of necessary infrastructure for the metro line.

The Kalena Agrahara to Nagawara stretch, spanning 21.26 km and encompassing 18 stations, is a crucial addition to the city's metro network. This stretch includes both elevated sections and underground tunnels, ensuring efficient connectivity across various parts of the city.

The Hosahalli-Kadabagere Metro works may commence by year-end, if approved by the Centre. BMRCL has initiated preliminary works, including the land acquisition process and other necessary tasks. The plan is to execute the works in phases, with over 100 acres of land already identified for the project. Approx. 75 acres of land near Byadarahalli police station is earmarked for depot construction, while an additional 25 acres are required for building a flyover.
