The Peripheral Ring Road (PRR) in Bangalore, also known as Bengaluru Business Corridor (BBC), is a major infrastructure project aimed at easing traffic congestion beyond the Outer Ring Road (ORR). Developed by the Bangalore Development Authority (BDA), it promises enhanced connectivity and economic growth for the city.
Introduction to Peripheral Ring Road Bangalore
Current roads have given way with Bangalore's rapid urbanization; like the ORR, which handles over 10,000 trucks daily as a de facto bypass. The Peripheral Ring Road Bangalore addresses this by creating an outer ring to divert interstate and long-distance traffic, reducing intra-city congestion and the urban heat island effect. Spanning north and east Bangalore, this 8-lane access-controlled expressway with service roads will integrate with NICE Road, forming a complete 116 km bypass around the city. Approved under a PPP-DBFOT model, it targets completion by late 2027, boosting logistics and real estate along its corridor.
Peripheral Ring Road Bangalore Plan & Project Overview
The Bangalore peripheral ring road plan originates from BDA's vision to decongest ORR amid Bangalore's expansion beyond it, with the project notified in 2007 but revived in 2022 and rebranded as Bengaluru Business Corridor in 2024-2025. Estimated at Rs 27,000 crore, it features a 100m right-of-way (RoW), 8 main lanes (3.5m wide each), 6 service lanes, cycle tracks, and provisions for future metro. The government funds land acquisition, while the concessionaire handles construction, tolling for 50 years, and maintenance under PPP-DBFOT.
