Vegetation growing through cracks, possible moisture ingress, concrete cracking and signs of reinforcement corrosion have raised concerns over Bengaluru’s 23-year-old KR Puram cable-stayed bridge. The bridge, commissioned in 2003, carries four lanes of traffic over the Krishnarajapuram railway station. With traffic volumes and vehicle loading having increased significantly over the years, experts say the visible deterioration should prompt a comprehensive structural assessment — not just routine surface repairs.
So, how is the bridge performing against its original design assumptions? What should a proper Structural Health Monitoring programme examine? And should Bengaluru undertake a city-wide assessment of its ageing bridges and flyovers? Watch the full report to understand the warning signs, the engineering concerns and what authorities could do next. Do you think Bengaluru’s ageing bridges need more regular structural monitoring?
