The Peripheral Ring Road (PRR) is a 73 km ring road^[1] under construction^[2] that runs around Bangalore, Karnataka,^[3] which is outside of Outer Ring Road, Bangalore, which is a 60-kilometre-long road.

History

The reason for creating the PRR was to decongest the Outer Ring Road which currently acts as a by-pass to the city with more than 10,000 trucks using it. According to BDA's project report, with the immense growth in intra-city traffic, the ORR is under tremendous pressure already^{[citation needed]}. The city has already extended beyond the ORR which is a key factor in the increasing pressure on ORR.

In order to relieve the traffic pressure on the ORR and the major road networks of the city, a peripheral ring road (PRR) of 116 km was planned outside of the ORR. This stretch is planned to not only improve connectivity of areas beyond the ORR, but also ease the congestion on the ORR. The BDA was focussed on the first phase of the project from Hosur Road to Tumakuru Road with a distance of 67 km.^[4] While 1,810 acres were notified for acquisition in the final notification in 2007 for the Peripheral Ring Road (PRR) project, the Bangalore Development Authority (BDA) barely managed to acquire 3.21 acres of land.^[5] Urban Development Minister Byrathi Suresh “The PRR is an essential project for Bengaluru, and exploring Public–private partnership, else Bangalore Development Authority will take up the work, responsibility for executing the entire project."^[6]
