In Chennai, a tunnel boring machine named Anaimalai completed a 925-metre-long tunnel between Ayanavaram and Otteri metro stations, achieving a breakthrough earlier this month as part of the 116.1km phase-2 project. The tunnelling began on October 23, 2023. CMRL managing director M A Siddique and other officials attended the event. This stretch is part of the 9km underground section on the 45.4km corridor-3, running from Madhavaram Milk Colony to Siruseri Sipcot. Seven tunnel boring machines are deployed in this stretch, with a total of 23 machines to be used throughout the phase-2 project.
In Chennai, progress was made in the Metro's phase-2 project with the completion of a tunnel between Ayanavaram and Otteri metro stations. The tunnel boring machine (TBM) named Anaimalai, which commenced its journey on October 23, 2023, successfully constructed a 925-metre-long tunnel, culminating in a breakthrough at the Otteri metro shaft earlier this month. This milestone is part of the extensive 116.1-kilometer phase-2 metro expansion project, aimed at enhancing the city's transit infrastructure.
The event marking the breakthrough was attended by CMRL (Chennai Metro Rail Limited) managing director M A Siddique, alongside other key officials, underscoring the importance of this achievement. The newly completed tunnel forms a crucial segment of the 9-kilometre underground portion of corridor-3, which spans a total distance of 45.4 kilometres, connecting Madhavaram Milk Colony to Siruseri Sipcot. This corridor is pivotal in the larger scheme of the metro's phase-2 expansion, designed to improve connectivity across Chennai.
To tackle the ambitious tunnelling tasks in this corridor, a total of seven tunnel boring machines have been deployed. These machines are instrumental in carving out the necessary underground pathways that will facilitate seamless metro operations upon completion. The successful deployment and operation of Anaimalai signifies the efficiency and progress of the project, reflecting the meticulous planning and execution involved.
The phase-2 project itself is an extensive undertaking, featuring three corridors that collectively cover 116.1 kilometres. This expansion is set to significantly bolster Chennai's public transportation network, easing traffic congestion and providing a reliable alternative for commuters. Throughout the entirety of phase-2, a total of 23 tunnel boring machines are slated to be used, highlighting the scale and complexity of the project.
Overall, the completion of the Ayanavaram to Otteri tunnel marks a critical step forward in the Chennai Metro's phase-2 expansion. The involvement of advanced machinery, along with the dedication of the CMRL team, demonstrates a commitment to enhancing urban mobility in Chennai. As the project progresses, these developments promise to bring substantial improvements to the city's infrastructure, paving the way for a more connected and accessible metropolitan area.
