Construction work is progressing beneath Chennai's famous Marina Beach as part of the city's major metro rail expansion project. The work is focused on the upcoming Lighthouse Metro Station, which will be an important station on Corridor-4 connecting Lighthouse and Poonamallee.

Chennai Metro New Station near Marina Beach
The new station is being built close to Marina Beach, one of Chennai's most recognizable landmarks. Once completed, it will improve connectivity between the city centre, residential areas, and western suburbs. The station forms part of Chennai Metro Rail's ambitious 118.9-kilometre Phase-II expansion project, which aims to make travel across the city faster and more convenient.
Chennai Metro Construction Work
Large-scale construction activity can now be seen near the beach, where engineers and workers are developing underground metro infrastructure. The Lighthouse Metro Station will serve as a key stop on the Lighthouse-Poonamallee corridor, helping thousands of commuters travel more efficiently every day.
The project has reached several important milestones in recent months. Metro authorities completed tunnelling work between Lighthouse and Thirumayilai stations, overcoming challenges such as rocky ground conditions and underground gas pockets. This achievement brings the corridor a step closer to completion.
How will this Metro Extension Benefit Passengers?
The metro expansion is expected to significantly improve access to Marina Beach and the surrounding neighbourhoods. People travelling from areas such as Poonamallee and other parts of Chennai will be able to reach the beachfront more easily and quickly once the corridor becomes operational.
The development represents a new chapter in Chennai's transport network, combining modern infrastructure with one of the city's most iconic coastal locations. As construction continues, the Lighthouse Metro Station is steadily taking shape beneath the sands of Marina Beach, promising better mobility and reduced travel times for residents and visitors alike.
