According to reports, the Bengaluru Business Corridor will have a total width of 65 metres, out of which 41 metres will be used for the expressway and the Metro corridor.

After nearly two decades of delay, Bengaluru’s Peripheral Ring Road (PRR) project is finally moving forward. The 74-kilometre stretch has been renamed the ‘Bengaluru Business Corridor (BBC)’, with several new features added to the plan. The updated design includes an 8-lane expressway and a 5-metre-wide median reserved for a future Metro line.
According to BBC Chairman L.K. Atheeq, the road will have a total width of 65 metres, out of which 41 metres will be used for the expressway and the Metro corridor. On both sides of the expressway, there will be two service roads, each 9 metres wide, featuring two lanes and a cycling track. In addition, 3-metre-wide pavements will be built for pedestrians.
Why the Bengaluru Business Corridor was delayed
The project was stalled mainly due to land acquisition problems. To resolve this, the government is now offering five compensation options to landowners:
- Cash payment
- Transferable Development Rights (TDR)
- Enhanced Floor Area Ratio (FAR)
- Developed residential land
- Commercial land along the corridor
Special Land Acquisition Officers have been appointed to gather landowners’ choices and finalise compensation packages.

Key features of the Bengaluru Business Corridor (BBC)
- 5-metre median reserved for a future Metro corridor
- 8-lane expressway spanning a total width of 65 metres
- 41 metres dedicated to the expressway and Metro section
The corridor will begin in the west at the Bangalore International Exhibition Centre (BIEC) on Tumakuru Road (NH-4), pass through Ballari Road beyond Yelahanka, and connect to Old Madras Road and Electronics City, before finally joining NICE Road at Hosur Road junction. This alignment will integrate northwest and northeast Bengaluru into a single growth corridor.
