The Tuticorin Airport expansion project has received environmental clearance after the Expert Appraisal Committee (EAC) of the Ministry of Environment, Forest and Climate Change suggested the proposal. The EC is for expansion of the runway with blast pad, taxiway, isolation bay, new domestic terminal building and other works for Rs 3.80 billion. The expansion of the runway will make the total runway length from 1,350 m x 30 m to 3,115 m x 45 m. The existing runway width would be raised from 30 m to 45 m by building a 7.5-m-wide pavement on either side of the centre line of the runway.
