The Bengaluru Peripheral Ring Road (PRR) project has achieved a significant milestone by securing environmental clearance from the Ministry of Environment, Forest and Climate Change. This development is expected to accelerate the construction of the 73-kilometer, six-lane expressway, which aims to decongest the city's traffic and provide a seamless connectivity option for commuters.
Project Details and Route
The PRR will connect National Highway 44 (NH-44) near Devanahalli to National Highway 48 (NH-48) near Nelamangala, passing through several key areas. The road is designed to have six lanes with provisions for future expansion. It will feature 11 interchanges, 14 major bridges, and 28 minor bridges to ensure smooth traffic flow. The project also includes service roads, pedestrian pathways, and cycle tracks to promote sustainable mobility.
Environmental Clearance Conditions
The environmental clearance comes with several conditions that the implementing agency, the Karnataka Road Development Corporation Limited (KRDCL), must adhere to. These include obtaining consent from the Karnataka State Pollution Control Board, ensuring proper disposal of construction waste, and implementing a comprehensive environmental management plan. The project must also plant two trees for every tree cut and develop green belts along the road.
Additionally, the clearance mandates that the project should not disturb any water bodies or wetlands. The KRDCL is required to conduct regular environmental audits and submit compliance reports to the ministry every six months. The project will also need to install noise barriers in sensitive areas and use environmentally friendly construction materials.
Traffic and Economic Impact
The PRR is expected to significantly reduce travel time for commuters, especially those traveling between the northern and western parts of Bengaluru. It will also help in diverting heavy vehicular traffic away from the city center, thereby reducing pollution and congestion. The project is anticipated to boost economic activities in the peripheral areas, attracting investments in real estate, commercial spaces, and industries.
According to estimates, the PRR will carry around 1.5 lakh vehicles per day by 2035. The project cost is pegged at approximately Rs 8,000 crore, with funding from the state government and possible assistance from the central government under the Bharatmala Pariyojana scheme.
Land Acquisition and Rehabilitation
Land acquisition for the project has been a major challenge, with about 1,200 acres of land required. The KRDCL has already acquired 70% of the land, and the remaining acquisition is in progress. The project involves the rehabilitation of 2,500 families, for which a comprehensive resettlement plan has been prepared. The affected families will be provided compensation as per the Right to Fair Compensation and Transparency in Land Acquisition, Rehabilitation and Resettlement Act, 2013.
Timeline and Next Steps
With the environmental clearance in place, the KRDCL aims to start construction within six months. The project is expected to be completed in four years. The next steps include obtaining forest clearance for the stretch passing through the Doddaballapur forest area and securing approval from the National Highways Authority of India for the interchange designs.
The Bengaluru PRR is one of the key infrastructure projects planned to transform the city's transportation landscape. Once operational, it is expected to provide a much-needed alternative route for long-distance traffic and reduce the burden on the city's existing road network.
