A five-Ft portion of Pedder Road, opposite the Prabhukunj building near Cadbury House, caved in on Thursday, leading to traffic snarls on the stretch that was shut to undertake repair work through the day. The cave-in, officials said, happened after a slab of a stormwater drain under the road collapsed.
BMC officials have said temporary repair work would be completed by Thursday night itself to ease traffic on the bridge. “We were immediately at the spot after the traffic control room alerted us in the morning and started with the repair work. The work will be finished early to avoid inconvenience to the citizens,” said P R Masurkar, assistant commissioner of the D ward.
L S Vhatkar, chief engineer of the stormwater drains department, said the drains would have to be replaced for a long-term solution.
“The top-portion of the slab which is used to cover the drain collapsed, leading to a cave-in. Although we have started the repair works, we will have to fix it with an alternative drain as two major pipes have also been damaged,” said Vhatkar.
Despite Pedder Road facing problems due to underground utilities, BMC is yet to implement steps to tackle the issue. Two years ago, the civic body had planned to import a Ground-Penetrating Radar machine of European make which would help detect probable road cave-ins, culvert collapses and also be used during construction of retaining walls and paver blocks. The machine, which costs around Rs 25 lakh, would be procured in the next two months, Vhatkar added.
In 2012, there were three separate cave-in incidents on Pedder Road. A portion of Pedder Road near Jaslok Hospital caved in causing traffic snarls in September that year and a portion on Gamadia Lane caved in in October. Earlier, in July, a portion of the road caved in near Gamadia Junction, causing traffic jams for nearly two days.
