Equalising tunnel charges and imposing road tolls will solve problem, they say Surveyors have entered the widening argument over the Central-Wan Chai bypass, urging the public to say no to the project when they are consulted next month. The Royal Institution of Chartered Surveyors (RICS) said the government had failed to consider other methods to solve traffic congestion that did not involve reclamation of the harbour. The government will publish a new information kit about the bypass next month. The move follows an aborted attempt in late January to kick-start the project by outlining three proposals for reclaiming up to 25 hectares of Wan Chai waterfront. The proposals - released in the name of the Harbour Enhancement Committee - were withdrawn shortly afterwards because of a public outcry over the fact that some committee members had not even seen the plans. Roger Nissim, chairman of RICS Hong Kong's external affairs and public concerns committee, said equalising tunnel charges and adopting a sophisticated toll system for Central should be done before a bypass was considered. 'We have got a crazy pricing system for our tunnels. The busiest tunnel is the Cross-Harbour Tunnel, which is the cheapest,' said Mr Nissim, who is also a project planning manager for Sun Hung Kai Properties. The toll fees for private cars and light goods vehicles using the government-owned Cross-Harbour Tunnel are $20 and $15 respectively, while the corresponding fees for the privately owned Western Harbour Crossing are $40 and $55. If equalising the tolls failed to solve congestion, Mr Nissim said an electronic road payment system (ERPS) could be introduced in Central. The system would see road users charged more at peak hours and less on weekends. Mr Nissim believed an ERPS could solve the congestion problem, contrary to the government's argument that it would not work unless combined with a bypass. If it came to the worst and a bypass were considered, Mr Nissim said an underwater tunnel was preferred. The roof of that tunnel should be a cycle track and a footpath 'so that you and I can walk on the waterfront and enjoy the view'. The bypass was the target of a protest yesterday when a fleet of boats carrying activists sailed along Victoria Harbour. The Society for the Protection of the Harbour said it would speak directly to the acting chief executive to object to the plans should Tung Chee-hwa resign. The society also called on candidates in the running for Mr Tung's post to promise to protect the harbour. 'A forward-thinking chief executive must have the determination and moral courage to treasure the Earth and protect natural resources, and not just focus on short-term financial gains,' said Christine Loh Kung-wai, chairwoman of the society.
