Gurugram, Dec 19 (IANS): The contractor and officials of the National Highway Authority of India (NHAI) have been booked in connection with the falling off of a portion of the Rampura flyover on the Delhi-Jaipur national highway on Monday, police said on Wednesday.

The case was registered on the complaint of a group of Right to Information (RTI) activists including Ramesh Yadav, Baldev Mehra, Omprakash Kataria and others.

"The nexus of contractor and NHAI officials used poor construction materials intentionally to dupe public money that caused the flyover to break off," the complaint read.

The accused have been booked under Section 336 (endangering life or personal safety of others) and Section 34 (common intent) of the Indian Penal Code at Kherki Daula Police Station, Yadav told IANS.

About a six square feet portion of the flyover in Haryana fell off on December 17. The flyover is nearly 46 km from Delhi.

"The affected portion of the expressway has been cordoned off and is being repaired. It would take at least ten more days to make it fully functional," an official said.

"Light traffic is passing on the elevated road using the two lanes. Traffic passing under the affected flyover has been completely stopped as repair work by NHAI is in progress," chief of Manesar traffic police station Munesh Kumar said.

The flyover was opened for traffic nearly two years ago. A portion of another flyover near Manesar and Hero Honda Chowk had fallen down earlier in 2018.
