Even as Bengaluru’s tunnel road proposal remains under tendering, the 110 km elevated corridor project has taken a significant step forward with its Detailed Project Report (DPR) cleared by the technical advisory committee of the Greater Bengaluru Authority (GBA), according to a New Indian Express report.
The corridor, designed at a cost of Rs 18,000 crore, including Rs 3,000 crore allocated for land acquisition is now likely to be sent to the state government for approval by 25 September.
If the green light is granted, work could begin as early as December, with completion targeted within 25 months.
“The government has already given in-principle approval for the project. Once it gives its nod for the DPR, the work will start by December,” BS Prahallad, Director (Technical), Bengaluru Smart Infrastructure Ltd (B-SMILE) was quoted as saying by TNIE.
He confirmed the corridor will be tolled and executed under the Public Private Partnership (PPP) model, though B-SMILE will not decide the toll.
Entirely elevated, the corridor is planned along arterial roads and will include entry and exit points at selected junctions.
“We prepared the DPR after studying the city’s traffic for one year. We got many ideas while preparing the DPRs and all those ideas have been incorporated,” Prahallad explained
The project will employ Ultra-High-Performance Fibre-Reinforced Concrete, with components precast and factory-manufactured to ensure durability and precision.
B-SMILE officials visited Nagpur to study the technology, which promises enhanced quality and faster execution.
The elevated network will radiate across outer Bengaluru, offering faster interchanges and even a dedicated link to the airport road.
According to Prahallad, “The toll will be like on the Bengaluru Mysuru Expressway.”
The DPR was prepared jointly by Infra Support, Kannan Siddishakthi and Nagesh Consultants, pooling their expertise to develop a unified plan for the mega project.
