So, what exactly is an elevated metro corridor?

It is a transit route built above ground level, often as a double-decker structure, integrating metro and roadways to maximize space and improve flow. The idea is simple but impactful — offer better connectivity to the city’s existing metro and road networks while reducing the traffic snarls that Bengaluru commuters face daily.

Traffic congestion is not just an inconvenience but a crisis for the IT capital. With a population exceeding 1.4 crore and 1.2 crore vehicles on its roads — plus thousands more entering from across Karnataka and neighbouring states every day — the current infrastructure is under relentless pressure.

This project isn’t an isolated effort. The newly established Greater Bengaluru Authority (GBA) has already lined up 16 elevated corridors, with a whopping ₹13,000 crore allocation. Separately, approval is also in place for a 17.7 km twin-tunnel stretch from Esteem Mall, Hebbal, to Silk Board Junction, at a cost of ₹17,780 crore.
