Big Efforts for City Decongestion : Bangalore Peripheral Ring Road

The PRR is planned as a 74 km stretch with a 100-meter-wide road.

Peripheral Ring Road (PRR)

On completion, it will connect Tumakuru Road and Hosur Road via Hessaraghatta Road, Doddaballapur Road, Ballari Road, Hennur-Bagalur Road, Old Madras Road, Hoskote-Anekal Road, and Sarjapur Road. Along with NICE Road, which links Tumakuru Road and Hosur Road via the city’s northwestern, western and southwestern areas, Bengaluru will have a 116-km-long bypass on its periphery.

The proposed alignment of PRR will be located at an approximate radial distance of 17 km - 25 km from the city centre and is envisaged to be a bypass to the city for the long-distance personalised vehicles (cars and cabs) and commercial vehicles (trucks and LCVs). The total land requirement for the project, which was initially estimated to be 733 hectares (1811.28 acres), was later revised to 1036.51 hectares (2561.27 acres) due to the change in length of PRR from 65.5 km to 74 km. The increase in length was due to realignment and inclusion of cloverleaf structures to integrate at Tumkur Road and Hosur Road with NICE road.

The project’s total cost is Rs 14,934 crores, out of which Rs 9,318 crore is required for land acquisition and rehabilitation purposes, while the construction cost is estimated to be around Rs 5,600 crores. The state government has already provided administrative approval for the project. When originally conceptualised 15 years ago with the aim of decongesting Bengaluru and easing traffic, the project was estimated to be Rs 3,000 crore. But due to design, rapid urbanisation, and land acquisition challenges, the project could never take off despite repeated attempts.
