Large sinkhole on Sumanahalli flyover exposes BDA’s quality of work

Bengaluru: It’s not just the roads in Bengaluru which are full of potholes. A large sinkhole appeared on the Sumanahalli flyover on Friday, creating a sense of panic among the regular motorists. The flyover, located on Magadi road, was built by the Bangalore Development Authority (BDA) only about 10 years ago. 

“A portion of Sumanahalli bridge crumbled and collapsed on the road during the peak hour on Friday,” The New Indian Express first reported the news in its print edition on Saturday. “No commuter or vehicle came under the falling debris.”

The damaged portion of the flyover was barricaded soon after motorists brought it to the notice of City traffic police. The BBMP officials also rushed to the spot to inspect the condition of the flyover. The BDA, which built the flyover, blamed the civic body for not maintaining the bridge regularly. 

“Damage to Sumanahalli flyover is due to standing rain water and constant heavy vehicle movement. Experts also flagged poor maintenance & improperly mixed additives that led to poor bonding while it was being built. Have blacklisted builder, will repair damage & allow traffic,” B.H Anil Kumar, BBMP Commissioner said on Twitter. 

This is, however, the first instance in the City where a flyover developed a sinkhole. Such was the damage that the bright sky was clearly visible for people who stood right below the bridge and looked up. In the past, motorists had noticed cracks in the Hebbal and KR Market flyovers which, the experts said, were due to poor maintenance. 

BBMP Commissioner’s rationale on blaming the rainwater and the heavy movement of vehicles attracted funny responses on Twitter. “I don’t think builder has any fault here. It’s the rain water and heavy vehicles. We should find a way to stop rain and movement of heavy vehicles on flyovers. Right, sir?,” Girija Prasad Panda wondered. 

A few others brought to the notice of commissioner some of the roads and flyovers which are in bad shape. Some Twitter users, meanwhile, demanded the BBMP to disclose the name of the contractor who built the flyover.
