Tunnelling for the much-hyped and the longest underground Metro corridor — between Dairy Circle and Nagawara (14-km) — in Bengaluru is set to start shortly. For the tunneling works, which is a part of the Gottigere-Nagawara section (Red Line), L& T has received bids for the underground section from Vellara Junction to Shivajinagar and Shivajinagar to Pottery Town (2.8km), and along with BMRCL the company has been conducting soil tests along the section since March. The firm will build five stations, including Vellara Junction, MG Road, Shivajinagar, Cantonment and Pottery Town. The underground Metro alignment reaches below the Hosur Road crossing Richmond Road at Vellara Junction and then traverses below Brigade Road and crosses MG Road underneath the Purple Line. The underground MG Road integrated station is planned on Kamaraj Road, about 50-m from the platform edge of the existing elevated MG Road station. After MG Road, the underground alignment crosses Cubbon Road, takes a left turn and traverses below the defence land and by the side of the Infantry Road and turns right to reach the Shivajinagar bus stand area, where a station is planned in Chhota Maidan. Further, the alignment crosses below the built-up areas by the side of Queens Road and then crosses Cantonment Railway Station to reach Bamboo Bazaar playground, where another station will be set up, and traverses below Benson Town area and reaches Featherlite Pottery Town Government High School, where another station is planned. The project will be completed by 2024.
