A stretch of the Kazhakuttam-Mukkola bypass corridor where soil nailing technology was used for protection and stability of the embankmentmore-inSoil nailing technology has come to the aid of the National Highways Authority of India (NHAI) for the stablisation of steep slopes along the Kazhakuttam-Karode bypass corridor of the National Highway 66. Following the success in Kuzhivila and as it was found to be durable and cost-effective, the NHAI is using the soil nailing technology to reinforce slopes which are more than four metres high. The NHAI is using the expertise of the IIT Chennai for the soil nailing technology in the bypass corridors that is being four-laned through EPC mode. In the 16.2 km Reach II from Mukkola to Karode on the Kerala-Tamil Nadu border, the NHAI is using the soil nailing technology widely to protect the embankments above a height of 4 metres. A top NHAI official said the EPC contractor L & T Constructions has been asked to use the soil nailing technology as the green field four-lane concrete highway being developed traverses through villages that has undulating terrain.
