Phase 2 of the Chennai Metro involves extensive tunnelling and construction work, which will extend the existing metro lines and cover more areas of the city. The new phase will include multiple new routes, enhancing the reach of the metro system and providing a more comprehensive transit network for residents.

The completion of tunnelling work is expected to accelerate the overall progress of Phase 2, leading to the introduction of new metro lines and stations. This expansion will not only improve public transportation but also contribute to reduced traffic congestion and environmental benefits by promoting the use of public transit over private vehicles.

The Chennai Metro's expansion is aligned with the city's vision of modernising its infrastructure to meet the needs of a growing population. The new phase is anticipated to significantly impact urban mobility, offering a more efficient and reliable mode of transportation for commuters.

This development underscores the commitment to enhancing urban infrastructure and supports the broader goal of creating a more connected and accessible city. As the tunnelling work progresses, the project will continue to play a key role in transforming Chennai's transportation landscape.
