A DAY after a portion of the August Kranti Marg road caved in Monday morning,traffic movement was restored in the area by Tuesday. However,the civic administration was unable to identify the exact cause of the cave-in,which was caused by a weakened water pipeline running underground.

“The road was repaired last night and traffic returned to normal. Water supply in the neighbourhood was minimally affected as the supply to these areas begin only at midnight,” said Parag Masurkar,assistant municipal commissioner of D ward.

Although BMC was unable to detect exact cause of the pipeline crack,it was repaired in about 12 hours.

“It is an underground pipeline and we could not detect the cause of the crack. The utilities are old and prone to breakage,” said Masurkar.

Soil corrosion and continuous seepage from century-old stormwater drains and water lines running underground have caused numerous road cave-ins in south Mumbai. Last year on the Peddar Road stretch,three road cave-ins were recorded between July and October

Meanwhile,BMC is yet to purchase a Ground-Penetrating Radar (GPR) machine,which would help detect probable road cave-ins,culvert collapses and could also be used during the construction of retaining walls,paverblocks etc.

The machine,to be procured at an estimated cost of Rs 25-50 lakh,will also aid in identifying soil component,rock structures and utilities up to 10 metres beneath the road surface.

After tender for the machine received poor response earlier this year,the tender has now been re-opened and is scheduled to be used after this monsoon season.

The portion of the August Kranti road opposite Cumballa Hill Hospital in Kemps Corner caved in Monday morning leaving peak-hour traffic to crawl in the South Mumbai area.

The cave-in was 6-foot-wide,10-foot-long and 5-foot-deep while the damaged water pipeline had a diameter of 12 inches.
