The road, which will also have an elevated 8 km stretch on Magadi Road, is expected to cost a whopping Rs 9,800 crore.
A key revision to the 32.15 km stretch involves changes at Goraguntepalya, where officials propose a new Metro station rather than an interchange at Peenya.
Bengaluru is set to get its longest flyover, stretching 32.15 km, along the outer ring road (ORR) between J P Nagar and Hebbal.
This road-cum-metro corridor will be similar to the double-decker project on the Ragigudda-Silk Board stretch in south Bengaluru and is expected to significantly ease traffic.
According to Deccan Herald, the elevated road, planned to cover 8 km on Magadi Road as well, will cost an estimated Rs 9,800 crore. Recently, Deputy Chief Minister D K Shivakumar inspected various locations, including Hebbal, BEL Road, and Summanahalli, to review the proposal.
Shivakumar explained that the elevated road would be incorporated into future Metro projects to avoid the high costs of acquiring properties for road widening. “We aim to follow the same design as Ragigudda Road, where the elevated road is being built,” he said.
The Namma Metro’s third phase, which spans over 40 km, will also feature double-decker corridors. A feasibility study is 90 percent complete, though the design changes have delayed the tender process for the civil works. However, the project has been approved by the Centre since August last year.
“This project is being designed with the next 30-40 years in mind,” added Shivakumar, with the costs split between the BBMP and Namma Metro.
To accommodate the double-decker system, major changes are planned for the 32.15-km stretch between JP Nagar 4th Phase and Kempapura. This includes a new Metro station at Goraguntepalya instead of an interchange station at Peenya, which will save 300 metres in length and reduce construction costs. The new interchange will connect to both Peenya and Goraguntepalya stations via separate travelators.
Though it may cause some inconvenience to Metro passengers, this design will help reduce traffic congestion in the area, especially for vehicles moving between Dr Rajkumar Memorial and BEL Circle.
The double-decker project is set to create a signal-free corridor and eliminate detours by building a direct surface road through properties currently owned by the Defence Ministry and the Central Manufacturing Technology Institute.
