It’s anticipated that the Namma Metro Pink Line (Kalena Agrahara-Nagavara) tunnelling mission will likely be accomplished by August. There have been three phases to the tunnel’s drilling; two of them are completed.
The Namma Metro Pink Line (Kalena Agrahara to Nagavara) tunnel mission in Bengaluru is nearing its conclusion and is anticipated to be accomplished in August this yr.
The tunnel was drilled in three phases; two of the phases are full, whereas the third section is now below progress, with 94 per cent of the drilling accomplished.
Within the third section, a 935-meter tunnel is being drilled by Tunga and Bhadra tunnel boring machines (TBMs) from KG Halli to Nagavara. On February 2, Tunga TBM started drilling southward, whereas on April 2, Bhadra TBM began drilling northward. It’s anticipated that these TBMs will likely be accomplished by July 31 and August 31, respectively.
In keeping with Occasions Now Information, the primary a part of the tunnel mission, which runs from Shadimahal to Venkateswarapuram (1066.80 m), and the second section, which runs from Venkateswarapuram to KG Halli (1185.80 m), are each accomplished.

When tunnelling is completed, observe set up and civil building are nonetheless in progress, experiences add. As well as, station constructing and observe alignment work are nonetheless in progress. It’s anticipated that by the tip of 2025, the road will likely be open for industrial use.
Moreover, a portion of the phase-II mission, with 18 stations, will stretch 21.26 km from Kalena Agrahara to Nagawara. It consists of a 12-station tunnel part from Dairy Circle to Nagawara and a 7.50 km elevated line with six stops from Kalena Agrahara to Swagat Street.
There are two sections to the 21.26-km Pink Line: a 7.5-km elevated portion and a 13.76-km underground part that may join Kalena Agrahara to Nagavara. The underground portion entails constructing twin tunnels spanning 20.992 km. Almost six of the 18 stations are elevated, and the 12 underground are almost completed, experiences Deccan Herald.
To construct the tunnels, Bangalore Metro Rail Company Restricted (BMRCL) used 9 TMBs. Seven of them—Varada, Rudra, Lavi, Vindhya, Avni, and Urja—have accomplished their work.
On February 2, Tunga, the eighth, set off on its final drive (KG Halli-Nagawara, 935 metres). Bhadra was the machine ranked 9. Following Thursday’s success, on April 7, 2024, work will resume on the mission’s final activity, a 939-meter tunnel that may run north from KG Halli to Nagavara.
Nevertheless, experiences state that December seems extra probably, regardless that the BMRCL acknowledged that Tunga and Bhadra will end their final tunnelling drives in August.
 tunnelling project will be completed by August.){kind=link}
