Most of the construction packages of National Highway (NH) 66 in Kerala, which have either collapsed or developed cracks, were built in violation of the Ministry of Road Transport and Highways (MoRTH) specifications, says an expert study.

Though the “inspection report on slope stability, protection measures for slopes, embankments, and other vulnerable locations on NH 66”, commissioned by the National Highways Authority of India (NHAI), following the incidents has not fixed the responsibility on any agency, it exposes serious lapses in the road construction.
