The district authorities have proposed three more sites near Kavali for the proposed airport of Nellore. The new sites were proposed after an expert committee raised some objections over two sites recommended before because of the presence of water bodies. Sources said officials have identified 2,360 acres in north Rajupalem (12 km from Nellore), 1,627 acres in Racharlapadu (23 km from Nellore) and 1,785 acres near Damavaram (30 km from Nellore) in Dagadarthi mandal. Of the three, Damavaram site said to be suitable for the airport since the government owns large tracts of land.
