In support of the Chief Executive's policy on greening, the LCSD initiated an improvement programme at the North Lantau Highway by planting about 5 000 heavy standard flowering trees of four metres in height and 70 millimetres in diameter and 100 000 flowering shrubs, at a cost of $10 million. The programme, which started in February 2001, was completed in October 2002.

    The project is intended to provide attractive scenery along the transport route serving the Hong Kong International Airport at Chek Lap Kok, for both residents and tourists. The extensive planting of flowering trees and shrubs has enhanced the highway's appearance.
