Why did the NH-66 road collapse?

Because the embankment was constructed on weak, waterlogged soil without necessary ground improvement, and drainage deficiencies led to failure beneath the RE wall.

Who is responsible for the collapse?

NHAI has blacklisted KNR Constructions and suspended the Independent Engineer. Further responsibility will be confirmed after official investigations conclude.

Could the collapse have been prevented?

Yes. Proper soil treatment, scientific drainage design, and site-specific engineering would have prevented the failure.

Is the NH-66 stretch safe now?

Traffic has been diverted. Final stability will depend on reconstruction following IIT-reviewed design and NHAI’s revised safety protocols.
