When will your Metro line open? How much will it cost? How many pillars are up, and how much work remains? A new website developed by a 24-year-old infrastructure enthusiast from Kalyan brings details of all 21 Metro corridors planned for the Mumbai Metropolitan Region under one digital roof, tracking everything from construction progress and project costs to tenders and delays.

Shashank Ballaya, a computer engineering graduate from Kalyan, works in his family business while developing websites and apps on the side. His fascination with Metro systems began with his first ride in Bengaluru in 2014. Announcements of Metro Lines 5 and 12, which will connect his hometown to the wider region, further fuelled his interest in tracking local infrastructure.
