Bengaluru Tunnel Road Project Faces Safety, Traffic Concerns
Imagine a new underground road is planned in Bengaluru, but experts are worried.
They checked the plan and found it might damage the existing subway trains' tunnels and cause more traffic jams.
The new road crosses under or goes near the subway tracks in many places.
This could put pressure on the subway tunnels.
Also, adding entrances and exits to the new road could make traffic worse at busy spots.
The experts say the road plan doesn't fit with the city's traffic plans.
Even with these concerns, the city is still planning to build the road.
DULT review of Bengaluru's tunnel project highlights potential risks to Namma Metro structures.
The proposed 16-km underground tunnel could cause stress interference and impact the structural integrity of Metro tunnels.
Traffic congestion is expected to worsen at several locations due to ramp construction and additional traffic.
DULT's review indicates the project does not align with the Comprehensive Mobility Plan and other policies.
Bengaluru Smart Infrastructure Limited has proceeded with global tenders despite the discrepancies.
