Lupu Bridge arch joinsBy Jane Tian, Shanghai Star. 2002-10-10 The world's longest steel arch bridge will be in operation next year SHANGHAI has another rainbow across the Huangpu River. The last gap in the arch of the Lupu Bridge was successfully closed when a 6.8-metre-long section was lifted into place 100 metres above the water on October 7. With 2.2 billion yuan (US$266 million) of investment, the 3,900-metre-long bridge breaks the record for this type of bridge with its 550-metre-long main arch, 32 metres longer than that of the New Virginia Bridge in the United States. The main arch is made up of 27 sections connected synchronously from both sides of the bridge toward the centre. "The precise connection depends critically on the temperature and the wind velocity, which can be very difficult to handle but worth the pain for Chinese bridge builders,?Lin said. The joining was expected to have been completed in April but due to technical difficulties, the work was delayed till this week. The bridge has consumed more than 35,000 tons of steel and the next big job will be paving the roadway for traffic and installing horizontal cables to fasten the arch. The rest of the work will not be a problem as local builders are experienced in these aspects of bridge construction, Lin said. According to Hu Shide, an anti-seismic expert in Tongji University, the bridge, guarded with an advanced safety belt, can meet the challenge of an earthquake that happens once in 3,280 years. Vice-Mayor Han Zheng expects the bridge to be completed and in operation by May next year to relieve cross-river traffic congestion. "The bridge will also contribute to Shanghai's bid for World Expo 2010,?Han said. "If the bid is successful, some four square kilometres near the ends of the bridge will be turned into a venue.? Han also pointed out that Shanghai will have two more river-crossing projects next year: the Outer-Ring Road Tunnel to be finished by May and the Dalian Lu Tunnel to be in opened by the end of next year.
