Macau officials say that they were kept in the dark over plans announced by Beijing this week for a 'superbridge' linking Zhuhai and Hong Kong. And a Legislative Assembly deputy said yesterday the Lingdingyang Highway Bridge could isolate the enclave and lead to serious traffic congestion in Hong Kong. Macau Undersecretary for Transport and Public Works, Alves Paula, said he would try to find out why the enclave was not told about the 16.6 billion yuan (HK$15.6 billion) project before yesterday's announcement. Zhuhai Municipal Party Committee Secretary, Liang Guangda, revealed at a press conference that the project had been given the go-ahead by chiefs in Beijing. Talks between Macau and Beijing had already been under way over a possible $14.1 billion bridge linking Lantau, Macau and Zhuhai. 'We believe the best solution for Macau is a bridge linking Hong Kong and Macau,' said Mr Paula. 'We are not opposed to any project but feel if this project has been given the go-ahead, we should have been informed beforehand.' Legislative Assembly Deputy Vitor Ng said that the Lingdingyang proposal could isolate Macau. He called on Zhuhai to 'concentrate on its own internal development' before looking at links with Hong Kong. 'I also believe that Hong Kong could have serious traffic congestion problems in a few years if this goes ahead,' he said. Hong Kong officials have not yet agreed to co-operate with Zhuhai on the project. They are still awaiting the results of a study on cross-boundary traffic demand.
