On the basis of complaints regarding non-worthiness of the recently constructed road, the Vigilance Bureau's Chief Director B K Uppal along with senior PWD and GMADA engineers and Central Road Research Institute (CRRI) experts inspected it, a spokesman said.
They excavated the road at two points and prima facie it has been found that the 200-feet thoroughfare was not designed properly and sub-standard material was used, he said.
Uppal said that the GMADA had already received a sampling report from the CRRI.
Uppal said that on the basis of CRRI reports further action would be initiated against the guilty engineers and the contractor.
