Pink Line Update: Bengaluru’s Deepest Underground Metro Nears Reality

Bengaluru’s most ambitious metro corridor yet is inching toward the finish line. The 21.3-km Pink Line — much of it deep underground beneath the city’s heart — is in its final stretch of track-laying and systems work.

The Pink Line route

The Pink Line connects Kalena Agrahara to Nagawara, running 21.3 km in two parts. A 7.5-km elevated stretch links Kalena Agrahara to Tavarekere, while a 13.76-km underground section runs from Dairy Circle to Nagawara via MG Road, with 12 underground stations.

This is the line that finally threads the metro directly through Bengaluru’s dense central spine — connecting neighbourhoods that road traffic has long made painfully slow to cross.

Tunnelling done, opening in phases

Tunnelling on the underground section was completed back in December 2024, and crews are now focused on track-laying and systems integration. The line is expected to open in phases: the elevated stretch targeted for around May 2026, and the underground section by December 2026.

Every one of the 12 underground stations — plus the elevated sections — will get Platform Screen Doors (PSDs), a major safety upgrade that keeps passengers away from the track edge until trains arrive.

Why the Pink Line is a milestone

Deep-bore underground metro is among the hardest infrastructure to build in a crowded city, and the Pink Line represents engineering Bengaluru has never attempted at this scale. When it opens, journeys across the central business district that once meant long, unpredictable road trips become quick, climate-protected metro rides.

For commuters, it’s the corridor that could redraw how people move through the heart of the city.
