A proposal to build a four-lane highway connecting Vallarpadam International Container Transshipment terminal with Nedumbasserry International Airport in Cochin has been put forward. The proposal is awaiting clearance from the empowered committee on infrastructure projects of the ministry of environment and forests. The committee recently visited Kerala to study environmental concerns raised over the highway project. It also held meetings with NHAI and CPT officials, and visited the project site and studied water bodies and terrain of the land.
