The Chennai Metro Rail Limited (CMRL) has started track installation on Corridor four of the Phase two expansion, covering the Porur to Poonamallee stretch. This milestone marks significant progress in Chennai’s metro expansion, which aims to enhance urban mobility and reduce traffic congestion.

The 26.1 km Corridor four, linking Lighthouse to Poonamallee, includes elevated and underground sections. The newly laid tracks on the elevated stretch between Porur and Poonamallee will soon be followed by electrification and trial runs. Once operational, this corridor will boost connectivity to western Chennai, providing faster and more efficient public transport options.

With Phase two spanning 118.9 km, the project is expected to transform Chennai’s transport network, easing travel for daily commuters and promoting sustainable urban development. Authorities are working towards a timely launch, ensuring seamless integration with existing metro lines.

This initiative aligns with the Tamil Nadu government’s push for modern, eco-friendly public transport, reducing dependence on private vehicles and improving commuter convenience across the city.
