MEMBERSHIP of a study group highly critical of government infrastructure policy has risen sharply. The Study Group for Infrastructure Development now has 50 members, up from 20. And it has been renamed the Hong Kong Institute for Infrastructure Development. Transport Advisory Committee chairman Dr Raymond Ho Chung-tai has joined as secretary. Other new members include the Land Development Corporation's Steven Chan Hung-kwan, Wing Lung Bank's Dr Philip Wu Po-him, and accountant Tan Man-kau. A Hong Kong affairs adviser to Beijing, Dr Wang Liang-huew, remains chairman. Deputy chairman Dr Wong King-keung said the group would shift its focus from Chek Lap Kok airport to other infrastructure development issues. 'Now the impasse between China and Britain over the new airport has come to an end, the group has to focus on other things,' he said. The institute is to conduct a study of the territory's transport system, with a special focus on the traffic congestion in Tuen Mun Highway. Other studies, including research on port development and land reclamation, will also be considered. A member said the changes were adjustments to the new political environment. 'With less than 20 months before the handover, the group could not remain a critic of the Government,' he said. 'It has to be transformed into an adviser for the future Special Administration Region government.'
