AT least part of the 123-kilometre Guangzhou-Shenzhen-Zhuhai Superhighway will be open to toll traffic by the end of the month, Hopewell Holdings managing director Gordon Wu Ying-sheung says. He said yesterday the electricity supply and road lights on the 18-km stretch between Taiping and Shigu were now being tested, and traffic would soon start. ''I told the boys I wanted to have something for my next birthday, which is on December 3,'' he said. But he hinted that Hopewell still had poor relations with the other partner in the joint venture, Guangdong Provincial Highway Construction Co. Mr Wu said: ''We [Hopewell] are aiming to finish the 75-km stretch we are responsible for by the middle of December. ''That is the most difficult bit. The bit the Chinese are doing is very easy. They should be finished by the end of the year. ''I remember when I took over last year they had only finished five to seven per cent. I had to do all these things in 15 or 16 months. ''I had to build more bridges in that time than the whole of Hong Kong has built in 150 years.'' He said the end was now within sight despite delays from bad weather. The contract deadline for completing the road is next June. Under a complicated bonus scheme, Hopewell could keep 100 per cent of the toll fees earned up to that date if the road is finished. Previously Mr Wu had hoped to finish in June this year and pick up a bonus of $900 million. Despite the delays, he was still optimistic yesterday. ''We won't be far off the mark because of the number of cars now utilising the roads,'' he said.
